We recommend freezing sperm before starting hormone therapy, in order to freeze the highest quality of sperm possible. The higher the quantity and quality of sperm, the more likely it is that you’ll be able to create a pregnancy with that sperm in the future.
However, we know this isn’t always possible, and that in many cases, people will begin hormone therapy prior to exploring fertility preservation. It may still be possible to freeze sperm even after starting GAHT/HRT. We recommend a semen analysis to assess fertility before freezing.
