Yes, FTM individuals can pursue fertility options after starting HRT. There are a few different options available, including:

  • Egg freezing: This involves retrieving eggs from the ovaries and freezing them for future use.
  • Ovarian tissue cryopreservation: This involves removing a small piece of ovarian tissue and freezing it for future use.
  • Sperm banking: This involves collecting and freezing sperm.

The best option for you will depend on your individual circumstances and preferences. It is important to talk to a doctor who is experienced in working with transgender people to discuss your options and make the best decision for you.

It is important to note that fertility options are not always successful. There is a chance that the eggs or sperm may not be viable after they are frozen. Additionally, the cost of fertility preservation can be expensive.

If you are considering fertility options, it is important to talk to a doctor about the risks and benefits before starting treatment.

Yes, FTM individuals can pursue fertility options even after starting hormone replacement therapy (HRT). While testosterone therapy typically leads to a cessation of menstrual cycles and a decrease in fertility, it is still possible to preserve reproductive capabilities and pursue fertility options if desired.

Here are a few fertility options that FTM individuals can consider:

  1. Egg Freezing: Prior to starting HRT, individuals can choose to undergo egg freezing (oocyte cryopreservation) to preserve their eggs for future use. This involves stimulating the ovaries to produce multiple eggs, which are then retrieved and frozen for later use. After transitioning, if the individual wishes to have biological children using their eggs, they can pursue assisted reproductive technologies such as in vitro fertilization (IVF) and use a sperm donor.
  2. Embryo Freezing: If a partner is involved, FTM individuals may choose to create embryos through IVF before starting HRT. Eggs are retrieved, fertilized with sperm from a partner or a donor, and the resulting embryos are frozen for future use. This option allows for the preservation of genetic material from both partners.
  3. Donor Sperm: FTM individuals who have not preserved their eggs or embryos can still have the option of using donor sperm for assisted reproductive procedures like intrauterine insemination (IUI) or IVF. This enables the individual to conceive a pregnancy using sperm from a donor.

It’s important to note that fertility preservation options and success rates can vary depending on factors such as age, individual health, and fertility status prior to HRT. It’s advisable to consult with a reproductive endocrinologist or fertility specialist who specializes in transgender fertility to discuss the available options, the best course of action, and the potential success rates based on individual circumstances.

Starting HRT does impact fertility, but it doesn’t necessarily mean that fertility options are completely off the table. It’s important to have open discussions with healthcare professionals early on in the transition process to explore and plan for fertility preservation if desired.

Fertility preservation

Fertility preservation refers to the process of safeguarding reproductive potential for individuals who may be at risk of infertility due to medical treatments, gender transition, or other reasons. It involves various methods aimed at preserving eggs, sperm, or reproductive tissues to be used in the future for conception. Here are some details on fertility preservation:

  1. Methods for Individuals Assigned Female at Birth (AFAB):
    • Egg Freezing (Oocyte Cryopreservation): Involves stimulating the ovaries with hormone injections to produce multiple eggs, which are then retrieved, frozen, and stored for future use. This method is commonly used for individuals AFAB who are considering gender-affirming treatments such as hormone therapy or surgery that may affect fertility.
    • Ovarian Tissue Cryopreservation: Involves removing and freezing ovarian tissue containing immature eggs. This method is still considered experimental and may be offered to individuals who cannot undergo egg retrieval due to medical reasons.
  1. Methods for Individuals Assigned Male at Birth (AMAB):
    • Sperm Banking (Sperm Cryopreservation): Involves collecting and freezing sperm samples for future use. This method is suitable for individuals AMAB who are considering hormone therapy or surgeries that may affect sperm production or quality.
    • Testicular Tissue Cryopreservation: Involves removing and freezing a small piece of testicular tissue containing sperm precursor cells. This method is considered experimental and may be offered to individuals who cannot produce sperm or undergo sperm banking due to medical reasons.
  1. Considerations for FTM Individuals Pursuing Fertility Preservation:
    • Timing: It is essential for FTM individuals to discuss fertility preservation options with their healthcare providers before starting hormone therapy or undergoing surgical interventions that may impact fertility.
    • Hormone Therapy: Testosterone therapy, commonly used as part of gender transition for FTM individuals, can suppress ovarian function and fertility over time. However, the degree of fertility impairment varies among individuals, and some may still retain fertility potential while on hormone therapy.
    • Reproductive Counseling: FTM individuals should receive comprehensive reproductive counseling to understand the potential impact of hormone therapy on fertility, available fertility preservation options, and the likelihood of success based on individual circumstances.
    • Cost and Accessibility: Fertility preservation procedures, such as egg freezing or sperm banking, can be costly and may not be covered by insurance. FTM individuals should inquire about financial assistance programs or explore alternative options if cost is a barrier.
  1. Future Family Planning:
    • Fertility preservation allows FTM individuals to retain the option of biological parenthood in the future, either through assisted reproductive technologies, such as in vitro fertilization (IVF), or natural conception if fertility is preserved.
    • It is important for individuals to discuss their future family planning goals with their healthcare providers and consider factors such as desired timing, available resources, and personal preferences when making decisions about fertility preservation.

 

Hormone replacement therapy (HRT)

Ovarian tissue cryopreservation

Procedure:

    • Ovarian Tissue Retrieval: The procedure begins with the surgical removal of ovarian tissue from one or both ovaries through laparoscopy or open abdominal surgery. A small portion of the outer cortex of the ovary, which contains the ovarian follicles containing immature eggs, is carefully dissected and removed.
    • Tissue Processing: The removed ovarian tissue is processed in the laboratory to isolate and prepare the ovarian follicles for cryopreservation. The tissue is typically cut into small pieces and treated with cryoprotectant solutions to minimize ice crystal formation and cellular damage during freezing.
    • Cryopreservation: The prepared ovarian tissue is frozen using a controlled-rate freezing or vitrification technique to preserve the viability of the ovarian follicles. The tissue is typically stored in cryogenic storage tanks at very low temperatures (-196°C) until needed.
  1. Indications:
    • Imminent Gonadotoxic Treatments: Ovarian tissue cryopreservation may be considered for individuals facing chemotherapy or radiation therapy that can damage ovarian function and fertility. It offers a rapid and effective way to preserve fertility in cases where there is insufficient time for ovarian stimulation and egg retrieval.
    • Medical Conditions: Individuals with certain medical conditions, such as autoimmune diseases or genetic disorders, that may require treatments or surgeries that could impact ovarian function may also consider ovarian tissue cryopreservation as a fertility preservation option.
  1. Advantages:
    • Rapid Procedure: Ovarian tissue cryopreservation can be performed quickly without the need for ovarian stimulation, making it suitable for individuals facing time-sensitive treatments.
    • High Oocyte Yield: Ovarian tissue contains numerous immature eggs (primordial follicles), potentially offering a higher yield of oocytes compared to traditional egg retrieval methods.
    • Long-Term Storage: Frozen ovarian tissue can be stored indefinitely, allowing individuals to preserve their fertility for an extended period until they are ready to pursue pregnancy.
  1. Limitations and Considerations:
    • Experimental: Ovarian tissue cryopreservation is still considered experimental and may not be widely available or covered by insurance.
    • Fertility Restoration: Restoring fertility from cryopreserved ovarian tissue typically involves a complex procedure known as ovarian tissue transplantation. The transplanted tissue must reestablish blood supply and hormone production to support follicular development and ovulation.
    • Ethical and Legal Considerations: Ovarian tissue cryopreservation raises ethical and legal considerations regarding consent, ownership, and disposition of stored tissue, as well as the potential risks and benefits of fertility restoration procedures.
  1. Future Directions:
    • Ovarian tissue cryopreservation continues to evolve with ongoing research aimed at optimizing cryopreservation techniques, improving fertility restoration outcomes, and addressing ethical and legal concerns.
    • Emerging technologies, such as in vitro maturation (IVM) of immature oocytes derived from cryopreserved ovarian tissue, hold promise for expanding fertility preservation options for individuals facing fertility-threatening conditions.

 

Assisted reproductive technology

  1. In Vitro Fertilization (IVF):
    • IVF involves the fertilization of eggs with sperm outside the body in a laboratory setting. The process typically involves ovarian stimulation to produce multiple eggs, followed by egg retrieval, fertilization in a culture dish, embryo culture, and embryo transfer into the uterus.
    • IVF may be used to treat various causes of infertility, including tubal factor infertility, male factor infertility, ovulatory disorders, endometriosis, and unexplained infertility.
  1. Intracytoplasmic Sperm Injection (ICSI):
    • ICSI is a specialized form of IVF that involves the injection of a single sperm directly into an egg to facilitate fertilization. It is commonly used in cases of male factor infertility, such as low sperm count, poor sperm motility, or abnormal sperm morphology.
    • ICSI may be recommended when conventional methods of fertilization, such as standard IVF or intrauterine insemination (IUI), have been unsuccessful or when there are concerns about sperm quality or quantity.
  1. Donor Gametes (Egg or Sperm Donation):
    • Donor gametes, including donor eggs or donor sperm, may be used in ART to achieve pregnancy when individuals or couples are unable to produce viable gametes of their own.
    • Egg donation is commonly used in cases of diminished ovarian reserve, advanced maternal age, or recurrent IVF failure, while sperm donation is used in cases of severe male factor infertility or genetic disorders.
  1. Embryo Donation and Embryo Adoption:
    • Embryo donation involves the transfer of donated embryos created through IVF to the uterus of the intended parent(s) or recipient(s) for implantation and pregnancy.
    • Embryo adoption is a form of embryo donation where individuals or couples adopt donated embryos with the intention of giving birth and raising the resulting child as their own.
  1. Preimplantation Genetic Testing (PGT):
    • PGT involves the genetic screening of embryos created through IVF to identify genetic abnormalities, chromosomal abnormalities, or genetic mutations that may impact embryo viability or increase the risk of inherited genetic disorders.
    • PGT can help select embryos with the highest likelihood of implantation and reduce the risk of miscarriage or the birth of a child with a genetic condition.
  1. Surrogacy:
    • Surrogacy involves the use of a gestational carrier (surrogate) to carry and give birth to a baby on behalf of intended parent(s) or recipient(s).
    • Gestational surrogacy may be used in cases where individuals or couples are unable to carry a pregnancy themselves due to medical reasons, such as uterine factor infertility, recurrent pregnancy loss, or medical conditions that contraindicate pregnancy.
  1. Legal and Ethical Considerations:
    • ART raises various legal and ethical considerations related to consent, ownership of gametes and embryos, parentage, donor anonymity, and the rights of children born through ART.
    • It is essential for individuals and couples considering ART to understand their legal rights and responsibilities, undergo comprehensive counseling, and make informed decisions about treatment options, including the use of donor gametes, embryo donation, surrogacy, and preimplantation genetic testing.

 

Egg freezing

Egg freezing, also known as oocyte cryopreservation, is a method of fertility preservation that involves harvesting and freezing a woman’s eggs (oocytes) for future use. Here are some details on egg freezing:

  1. Procedure:
    • Ovarian Stimulation: The process typically begins with ovarian stimulation, where the woman undergoes hormonal injections to stimulate the ovaries to produce multiple eggs. This usually takes about 10-14 days and involves monitoring the ovaries’ response through blood tests and ultrasound.
    • Egg Retrieval: Once the eggs have matured, they are retrieved through a minimally invasive procedure called transvaginal ultrasound-guided egg retrieval. A thin needle is inserted into the ovaries through the vaginal wall to aspirate the mature eggs.
    • Cryopreservation: The retrieved eggs are then immediately frozen using a process called vitrification. Vitrification involves rapidly cooling the eggs to very low temperatures (-196°C) to prevent the formation of ice crystals, which could damage the eggs’ structure.
    • Storage: The frozen eggs are stored in liquid nitrogen tanks at specialized cryopreservation facilities until they are needed.
  1. Indications:
    • Fertility Preservation: Egg freezing is commonly used for fertility preservation in women who wish to delay childbearing for personal, medical, or social reasons. This may include women pursuing education, career advancement, or personal goals, as well as those facing medical treatments that may impact fertility, such as chemotherapy or radiation therapy.
    • Reproductive Assistance: Egg freezing may also be used in cases where a woman’s partner has male factor infertility or genetic concerns, or in situations where a couple wishes to delay pregnancy but preserve their reproductive options.
  1. Success Rates:
    • Success rates of egg freezing vary depending on factors such as the woman’s age at the time of egg retrieval, the number of eggs retrieved, and the quality of the eggs.
    • Generally, younger women tend to have higher success rates with egg freezing, as they are more likely to produce a greater number of high-quality eggs.
  1. Limitations and Considerations:
    • Age: The success of egg freezing is largely influenced by the woman’s age at the time of egg retrieval. Fertility declines with age, and women are advised to freeze their eggs at a younger age to maximize the chances of success.
    • Number of Eggs: The number of eggs retrieved and frozen also plays a significant role in the success of egg freezing. While there is no guarantee of pregnancy with a certain number of frozen eggs, having more eggs increases the likelihood of having viable embryos for future use.
    • Cost: Egg freezing can be expensive, and costs may include ovarian stimulation medications, egg retrieval procedure, laboratory fees, and ongoing storage fees for the frozen eggs.
    • Ethical and Legal Considerations: Egg freezing raises ethical and legal considerations related to consent, ownership of the eggs, disposition of unused eggs, and future use of the frozen eggs.
  1. Future Use:
    • Frozen eggs can be thawed, fertilized with sperm through a process called intracytoplasmic sperm injection (ICSI), and transferred into the uterus or a gestational carrier’s uterus for implantation and pregnancy.
    • Not all frozen eggs survive the thawing process, and not all fertilized eggs develop into viable embryos. Therefore, there is no guarantee of pregnancy with frozen eggs, and individuals considering egg freezing should be aware of the potential limitations and uncertainties.

 

Sperm banking

Sperm banking, also known as sperm cryopreservation, is a method of fertility preservation that involves collecting and freezing a man’s sperm for future use. Here are some details on sperm banking:

  1. Procedure:
    • Sperm Collection: The process typically begins with the collection of a semen sample through masturbation. In some cases, sperm may also be collected through other methods such as surgical sperm retrieval techniques for individuals with certain medical conditions.
    • Semen Analysis: The semen sample is analyzed to assess the sperm count, motility (movement), morphology (shape), and other parameters. This helps determine the quality of the sperm and the suitability for cryopreservation.
    • Sperm Processing: The semen sample is processed in the laboratory to remove seminal fluid and other contaminants, leaving behind concentrated sperm cells.
    • Cryopreservation: The processed sperm is then mixed with a cryoprotectant solution to prevent damage from ice crystal formation during freezing. The sperm is then divided into small vials and frozen using a controlled-rate freezing or vitrification technique.
    • Storage: The frozen sperm vials are stored in liquid nitrogen tanks at specialized cryopreservation facilities until they are needed.
  1. Indications:
    • Fertility Preservation: Sperm banking is commonly used for fertility preservation in men who wish to preserve their fertility before undergoing medical treatments that may impact sperm production or quality, such as chemotherapy, radiation therapy, or surgical procedures.
    • Reproductive Assistance: Sperm banking may also be used in cases where a man has a medical condition or genetic disorder that may affect fertility, or in situations where a couple wishes to delay pregnancy but preserve their reproductive options.
  1. Success Rates:
    • Success rates of sperm banking are generally high, as sperm cells have a high tolerance for freezing and thawing compared to other types of cells.
    • The quality of the frozen sperm and the likelihood of successful conception depend on factors such as the man’s age, sperm quality, and the underlying reason for sperm banking.
  1. Limitations and Considerations:
    • Sperm Quality: The success of sperm banking is influenced by the quality of the sperm collected. Individuals with low sperm count, poor sperm motility, or abnormal sperm morphology may have reduced success rates with sperm banking.
    • Number of Samples: It is recommended to bank multiple semen samples to increase the chances of having viable sperm for future use. The number of samples collected may vary depending on individual factors and treatment plans.
    • Cost: Sperm banking can be expensive, and costs may include semen analysis, sperm processing, cryopreservation, and ongoing storage fees for the frozen sperm.
    • Ethical and Legal Considerations: Sperm banking raises ethical and legal considerations related to consent, ownership of the sperm, disposition of unused sperm, and future use of the frozen sperm.
  1. Future Use:
    • Frozen sperm can be thawed, evaluated for viability, and used for various assisted reproductive technologies (ART) such as intrauterine insemination (IUI), in vitro fertilization (IVF), or intracytoplasmic sperm injection (ICSI).
    • Not all frozen sperm survive the thawing process, and not all sperm cells fertilize eggs successfully. Therefore, there is no guarantee of pregnancy with frozen sperm, and individuals considering sperm banking should be aware of the potential limitations and uncertainties.

Ovarian tissue cryopreservation

 

  1. Procedure:
    • Ovarian Tissue Retrieval: The procedure begins with a surgical procedure to remove a portion of the outer cortex of one or both ovaries. This can be done via laparoscopy or laparotomy under general anesthesia.
    • Tissue Preparation: The removed ovarian tissue is processed in the laboratory, where it is dissected into small fragments to expose the primordial follicles containing immature eggs.
    • Cryoprotection: The ovarian tissue fragments are treated with cryoprotectant solutions to prevent ice crystal formation during freezing, which could damage the delicate follicular structure.
    • Cryopreservation: The prepared ovarian tissue fragments are then frozen using a controlled-rate freezing or vitrification technique. Vitrification involves rapidly cooling the tissue to very low temperatures (-196°C) to preserve cellular integrity.
    • Storage: The frozen ovarian tissue fragments are stored in cryogenic storage tanks at specialized cryopreservation facilities until they are needed.
  1. Indications:
    • Fertility Preservation: Ovarian tissue cryopreservation is commonly used for fertility preservation in women who are facing treatments such as chemotherapy or radiation therapy that may damage ovarian function and deplete the ovarian reserve. It may also be considered for women with certain medical conditions or genetic disorders that may impact fertility.
    • Reproductive Assistance: In addition to fertility preservation, ovarian tissue cryopreservation may also be used in cases where a woman desires to postpone childbearing for personal or social reasons, or in situations where other methods of fertility preservation, such as egg freezing, are not feasible or contraindicated.
  1. Success Rates:
    • Success rates of ovarian tissue cryopreservation may vary depending on factors such as the woman’s age at the time of tissue retrieval, the quality of the ovarian tissue, and the underlying reason for fertility preservation.
    • Studies have shown that ovarian tissue cryopreservation can result in the restoration of ovarian function and fertility in some women after transplantation of the frozen-thawed tissue.
  1. Limitations and Considerations:
    • Experimental Nature: Ovarian tissue cryopreservation is still considered an experimental procedure in many countries and may not be widely available or covered by insurance.
    • Fertility Restoration: Restoring fertility from cryopreserved ovarian tissue typically involves a surgical procedure called ovarian tissue transplantation. The transplanted tissue must establish blood supply and hormone production to support follicular development and ovulation.
    • Ethical and Legal Considerations: Ovarian tissue cryopreservation raises ethical and legal considerations related to consent, ownership of the tissue, disposition of unused tissue, and future use of the cryopreserved tissue.
