Ok, I never was all that worried about sperm before. This changed after meeting my girlfriend, now I don't believe in love at first sight, but i'm sure that we will be together for awhile.
So as such, one of the things she asked me was if I had the ability to produce sperm still. I explained that as far as I know i'm sterile due to the HRT. I had heard stories of transsexuals going off HRT temporarily to produce children, then going back on.
But I don't know if this is true. I also don't know what is involved with storing sperm, or even if there is an upkeep cost. Does anyone know?
