Hi, thanks for using healthcare magic
means that there is not a measurable amount of sperm.
It can be due to problems before the testes (inadequate level of hormones stimulating the testes) , problems at the testes (testes themselves are abnormal and not producing sperm) or after the testes (there is an obstruction preventing the sperm from exiting).
The normal level of hormone results indicate that there is no problem before the testes and the biopsy
will identify any testicular problems.
In terms of fertility
, it is possible to remove sperm directly from the testes for in vitro fertilisation if it not thought possible to conceive otherwise.
hope this helps
