Trans women, or individuals who have transitioned from male to female, do not have ovaries or a uterus. Thus, they cannot become pregnant or carry a pregnancy. However, there are aspects of family-building and parenting that are important to consider:

1. Biological Children: Trans women who wish to have biological children might consider sperm banking before starting hormone replacement therapy (HRT) or undergoing any surgeries. Hormone therapy can reduce fertility, and surgeries like orchiectomy (removal of the testicles) or vaginoplasty (creation of a neovagina) make natural biological parenthood impossible.
2. Surrogacy: If a trans woman has banked sperm before her transition, she can use a surrogate to have a biological child. The sperm can be used to fertilize an egg (either from a donor or the surrogate, depending on the arrangement), and the embryo can be implanted in the surrogate’s uterus.
3. Adoption: Adoption is another avenue for trans women who wish to become parents. However, it’s essential to be aware that adoption laws and regulations, as well as societal attitudes towards LGBTQ+ adoptive parents, can vary significantly by country and region.
4. Co-parenting: Some trans women may choose to co-parent with a partner or friend. If the co-parenting partner can conceive and carry a child, this might be an option.
5. Fostering: Becoming a foster parent is another potential route to parenthood. Like adoption, fostering regulations and attitudes can vary based on geographic location.
6. Transgender Reproductive Rights and Research: The area of reproductive rights and possibilities for transgender individuals is a topic of ongoing research, discussion, and advocacy. While certain reproductive steps like uterus transplants have been explored in cisgender women with conditions like MRKH (Mayer-Rokitansky-Küster-Hauser syndrome), as of my last update in 2021, uterus transplantation had not been performed in trans women, and it’s a procedure with significant medical and ethical complexities.

It’s crucial for transgender individuals to discuss their family-building desires and plans with healthcare providers who are knowledgeable about transgender health. This ensures that they receive accurate information and can make informed decisions about their future.
