The short answer is no — a cisgender man (someone born male) cannot get pregnant. Pregnancy requires a uterus, ovaries, and a functioning reproductive system that supports conception and gestation. A cisgender man does not have these organs. However, the question becomes more nuanced when we consider transgender men — individuals who were assigned female at birth but identify as men. A transgender man who has not had surgery to remove his uterus and ovaries can become pregnant. This article explains the biology behind pregnancy and what options exist for people who are male or identify as male.
Can a Cisgender Man Get Pregnant?
No. A cisgender man is born with male reproductive anatomy — testes, prostate, and a penis — and does not have a uterus, fallopian tubes, or ovaries. Without a uterus, there is no place for a fertilized egg to implant and grow. Without ovaries, there are no eggs to be fertilized. The male body produces sperm, not eggs, and cannot conceive a pregnancy. This is basic human biology and is not changed by any current medical procedure.
What About Transgender Men?
Yes, a transgender man can become pregnant if he still has a uterus and at least one ovary. Many transgender men choose to keep these organs, especially if they want to carry a pregnancy. Taking testosterone does not guarantee infertility, and ovulation can still occur. Some transgender men pause testosterone therapy to allow a menstrual cycle to return before trying to conceive. Pregnancy in transgender men is medically possible and has been documented. It is not a new phenomenon, though social awareness has increased in recent years.
For transgender men who have had a hysterectomy (removal of the uterus) or oophorectomy (removal of ovaries), pregnancy is no longer possible because those organs are gone. Similarly, if testosterone has been used long-term, it may affect fertility, but it does not permanently sterilize everyone.
How Does Pregnancy Happen Biologically?
Pregnancy starts with ovulation — an egg released from an ovary travels through a fallopian tube. If sperm meets the egg and fertilization occurs, the fertilized egg moves to the uterus and implants in the uterine lining. A hormone called human chorionic gonadotropin (hCG) signals the body to maintain the uterine lining and support the growing embryo. The uterus expands as the fetus grows over about 40 weeks.
So the necessary parts are: at least one ovary, at least one patent fallopian tube, and a uterus with a functioning endometrium. A cisgender man has none of these. A transgender man who has not undergone surgery to remove these organs has them and can become pregnant.
Can a Uterus Be Transplanted Into a Cisgender Man?
Uterus transplants have been performed in cisgender women who were born without a uterus or lost it to disease. The surgery is experimental and carries significant risks, including organ rejection and complications from immunosuppressive drugs. As of now, no uterus transplant has been attempted in a cisgender man. Several anatomical and hormonal barriers exist. A cisgender male body does not produce the hormones needed to support a pregnancy in the usual way, though exogenous hormones could theoretically be used. The lack of a vaginal canal would also require surgical creation of a route for delivery, typically via cesarean section.
Some researchers have discussed the theoretical possibility, but no successful uterus transplant in a male recipient has been reported in peer-reviewed literature. The procedure is far from routine and raises major medical and ethical questions. It is not an available option for anyone seeking pregnancy today.
What About Surrogacy?
Surrogacy is a legal and medical route for cisgender men who want a biological child. A surrogate — a woman who carries the pregnancy — is implanted with an embryo created using the man’s sperm and an egg from a donor (or an egg from the surrogate in some cases). The resulting child is genetically related to the man if his sperm is used. This does not make the man pregnant; it involves a third party carrying the pregnancy. Surrogacy laws vary by state and country, and it can be expensive.
For transgender men who are able to carry a pregnancy, surrogacy is not needed unless they do not want to carry the pregnancy themselves or cannot for medical reasons.
Does Taking Testosterone Affect Fertility in Transgender Men?
Testosterone generally suppresses ovulation and menstruation, but it does not guarantee permanent infertility. Some transgender men have become pregnant while taking testosterone, though this is less common. Many clinicians advise pausing testosterone therapy for several months before trying to conceive to allow natural menstrual cycles to resume. The evidence on how long it takes for fertility to return is limited, but most studies suggest that fertility can return within months. There is no proven harm to a fetus from prior testosterone use, but data are limited. Anyone considering pregnancy while taking testosterone should discuss it with a healthcare provider who has experience in transgender reproductive health.
What Are the Options for Transgender Men Who Want to Become Pregnant?
If a transgender man has a uterus and ovaries, he can conceive through sexual intercourse or assisted reproductive technology such as intrauterine insemination (IUI) or in vitro fertilization (IVF). Sperm can come from a partner or a donor. Many fertility clinics now offer care tailored to transgender patients, though access and provider knowledge vary.
If a transgender man has had a hysterectomy but still has ovaries, his eggs can be retrieved and used with a surrogate. Some choose to freeze eggs or embryos before starting testosterone if they want biological children later.
Is There Any Medical Procedure That Can Give a Cisgender Man a Uterus and Ovaries?
Not currently. The only way to acquire a uterus and ovaries is through transplantation, which as noted has not been done in a male body. A full reproductive system transplant would require connecting blood vessels, nerves, and a vaginal canal, and then managing pregnancy with hormones. The risks of such a procedure are extreme, and no ethical or practical framework supports it today. Gene editing and artificial womb technology are entirely experimental and not applicable to this question.
For all practical purposes, a cisgender man cannot become pregnant now or in the foreseeable future.
Frequently Asked Questions
Can a man get pregnant without a uterus?
No. A uterus is required to carry a pregnancy. Without one, implantation and fetal development cannot occur.
Can a transgender man get pregnant after being on testosterone?
Yes, it is possible. Testosterone suppresses ovulation but does not always cause permanent infertility. Many transgender men pause testosterone to conceive.
Can a cisgender man get pregnant through a uterus transplant?
Not currently. No uterus transplant has ever been performed in a cisgender man. The procedure remains experimental even in women and is not available for men.
What is the difference between surrogacy and a man getting pregnant?
In surrogacy, a woman carries the pregnancy for someone else. The man does not become pregnant himself. Surrogacy is a separate arrangement where the man can have a genetic child without carrying the pregnancy.
