Azospermia

Azospermia is the absence of sperm on standard microscopic examination.
The prevalence of azospermia is 1% among all men and 10-15% in infertile men.
Azospermia can be classified as obstructive ( normal sperm production ) or non–obstructive (decreased or absent sperm production).
A male with semen analysis suggestive of azospermia needs hormonal, urologic, genetic or ultrasonographic examinations to further evaluate the problem.


Poor sperm tests can result from incorrect semen collection technique, if the sample is not collected properly, or if the container is dirty, too long a time delay between providing the sample and its testing in the laboratory, too short an interval since the previous ejaculation, recent systemic illness ( flu or a fever can temporarily depress sperm counts)
If the sperm test is abnormal, this will need to be repeated after 6 weeks.
