Fertility & Pregnancy
How T Affects Fertility
Testosterone suppresses ovulation and menstruation, but the effect on fertility varies:
| Duration on T | Fertility Impact |
|---|---|
| 0–6 months | Gradually declining |
| 6–12 months | Significantly reduced |
| 1+ years | Usually low but not zero |
T Is NOT Contraception
Pregnancy is possible on T
Documented cases exist of trans men becoming pregnant while on testosterone. Use contraception if pregnancy is a concern.
Fertility Preservation
| Option | Details |
|---|---|
| Egg freezing | Before starting T (ideal) |
| Embryo freezing | With partner or donor sperm |
| Ovarian tissue freezing | Experimental |
Pausing T for Pregnancy
Some trans men pause T to become pregnant. T typically clears from the body within 2–4 weeks, and ovulation can resume within 3–6 months.
