Talk:Azoospermia

how

how long is semen alive when its been ejaculated.

It depends on the location. In the vagina, sperm cells may last as long as a couple of days. They may die within hours elsewhere. WhatamIdoing (talk) 22:43, 10 March 2010 (UTC)

The acidic environment of the vagina will kill sperm very quickly, however, in cervical mucus sperm can survive for several days. Lots of cervical mucus is produced at the time of ovulation and may act as a reservoir for sperm.Ekem (talk) 03:56, 18 June 2010 (UTC)

Definition appears completely wrong!

According this and numerous other similar websites azoospermia is the absence of sperm cells for whatever reason. This definition appears to be oligospermia. JRPG (talk) 22:18, 5 February 2017 (UTC)

Have edited to reflect absence of sperm and added a reliable source. Thanks. — soupvector (talk) 03:31, 6 February 2017 (UTC)

Genetic causes / inv(2)(p11.2q13)

Here is good (N=many) and bad (N=1) research and anecdotes relating inv(2)(p11.2q13) to azoospermia. Some documented fertility outcomes for pt. with this inversion. Note: Older studies don't identify subbands, so also search for inv(2)(p11q13).

Maybe this will help somebody starting an academic publication, or it could be included in a new Wikipedia article or just be a list in the present article under the genetic section.
