Feminizing hormone therapy might reduce your fertility, but you'll still need contraceptives to avoid undesired pregnancy. If you think you'll want biological children, you can talk to your doctor about freezing your sperm before starting hormone therapy.
Side effects of estrogen use in transwomen include:
- Reduced libido
- Erectile dysfunction
- Reduced ejaculation
Feminizing hormone therapy may include taking GnRH, finasteride, or cyproterone acetate. These treatments don't work to reduce or block your sperm production.
