Testosterone is a hormone that plays an important role in male fertility, and it can have serious consequences for a developing fetus. Taking testosterone during pregnancy is not recommended, and it is important to consult with a doctor before stopping any testosterone treatment. One side effect of testosterone treatment is infertility, as it decreases sperm production by decreasing levels of follicle-stimulating hormone (FSH). Fortunately, in most cases, infertility caused by testosterone treatment is reversible.
Men who have received testosterone for a shorter period of time are likely to recover more quickly. However, for a small percentage of men, infertility isn't reversible. In general, testosterone given through injections and granules is thought to be more likely to cause infertility than gels, although any form of testosterone supplement can alter the normal hormonal balance required for sperm production. If your partner takes testosterone, your concerns about getting pregnant are valid.
Testosterone supplements are likely to affect sperm production and your ability to get pregnant. Fortunately, there are some alternatives to TRT therapy for people with low testosterone levels that don't affect sperm counts. We also understand that stopping testosterone GAHT can be difficult and cause gender dysphoria for many people. This is because synthetic testosterone can decrease FSH, which is responsible for orchestrating sperm production in the body. Some transgender people choose to store their eggs for a future pregnancy before starting testosterone, both because of the impact of testosterone on fertility and because of the simple fact that fertility peaks at younger ages. The effect of testosterone on the uterus causes the lining to become thinner, which affects monthly bleeding, since the lining does not shed monthly in the same way as it did before testosterone (if a person was not taking other hormonal birth control methods).
When it comes to testosterone treatment, there are a few options available, including injections, patches, gels, and implants. Testosterone is needed for sperm production, but the level in the testicles where sperm is produced is many times higher than in the blood. Testosterone levels vary throughout the day and a man's testosterone level will vary from test to test. HCG therapy is another way to support testosterone production without affecting the side effects of sperm count. When it comes to menstruation and ovulation, testosterone affects the way existing hormones work, and this has an impact on both menstruation and ovulation. While you can still get pregnant with testosterone therapy, if you want to bring your pregnancy to term, you'll need to stop hormone therapy completely. Testosterone replacement therapy (TRT) is often used in men who have low testosterone levels (hypogonadism).
If your partner has low testosterone levels but you want to start a family, there are plenty of options available to you. Men of reproductive age should avoid testosterone treatment if they want to have biological children or consider freezing sperm for later use.
