Eight months ago, a lady, twenty years my junior, comes to dinner in Spain and is seated next to me at the table. Unbeknownst to me, our host is reprising her role as 'yenta' behind my back. Four months later, said lady invites me to have children with her, only we do not have much time as her clock is running up on her 40th birthday. We meet with a specialist her OBGYN refers us to. Afterwards, I convey a tearful apology about the rash decision made 31 years earlier, and the consequences it has wrought now. The doctor said "Of course, we can reverse the vasectomy; but you are ten years past any known regeneration of sperm, and the odds at 20 years are minuscule, less than one in a million; in your case, ‘we have no idea’.
