Chromosomal abnormalities in sperm higher after vasectomy reversal

is reversible, and if so, how long will it take before things get back to normal? Perhaps more importantly, will babies born after vasectomy reversal either conceived naturally or by ART have problems themselves?"

To date there have been no studies looking at these questions, he said, and his team are beginning the follow-up research. "We are collecting sperm during vasectomy reversal operations and will compare the aneuploidy rate of these and of the sperm we will collect each month in the future from the same men. This will help us understand what the dangers are. But in the meantime, I think that doctors need to be very aware of the possibility that babies born after vasectomy reversal may have problems."

Their findings may not affect babies conceived naturally after such a procedure, says Professor Sukchareon, since the female genital tract may select the best sperm for fertilisation. "But this is still uncertain, and until we know more it would probably be safer to freeze ejaculated sperm before vasectomy. We need a lot more evidence and research on this issue before we can be certain of avoiding the dangers."
