Absence of motile (and hence viable) sperm in the semen.
- ‘The cause of male infertility according to the medical model of infertility is due to abnormal sperm parameters, azoospermia and antisperm antibodies.’
- ‘Where the initial semen analysis reveals azoospermia a centrifuged sample should be examined for sperm in the pellet.’
- ‘The resultant obstructive azoospermia can be treated quite successfully with a combination of sperm aspiration and ICSI.’
- ‘In patients with azoospermia or severe oligospermia, the karyotype should be determined because of the increased incidence of karyotypic abnormalities in this population.’
- ‘Men with nonobstructive azoospermia and severe ogliospermia (fewer than 5 to 10 million sperm per mL) should be informed of the potential genetic abnormalities associated with azoospermia or severe oligospermia.’
