Important male terms also changed: oligospermia is a term for low semen volume that is now replaced by hypospermia to avoid confusion with oligozoospermia
, which is low concentration of spermatozoa in the ejaculate below the lower reference limit.
Exclusion criteria included aspermia, oligozoospermia
, hypospermia, asthenozoospermia, samples not produced via masturbation, contaminated samples, patients who were on medication that may affect semen parameters and patients younger than 18 years of age.
sup] Genome-wide association studies (GWAS) have identified several susceptibility loci and >200 single nucleotide polymorphisms (SNPs) that have been associated with oligozoospermia
Keywords: Male infertility, Non-obstructive azoospermia, Reproductive hormone, Severe oligozoospermia
, Y chromosome microdeletion.

Analysis of the relationship between defective sperm function and the generation of reactive oxygen species in cases of oligozoospermia
In contrast, if no detectable color change is observed, then that patient may be at high risk for azoospermia, oligozoospermia
, necrozoospermia, or asthenozoospermia.
About 30% of men reporting to infertility clinic are found to have oligozoospermia
, oligoasthenoteratozoospermia (OAT) and orazoospermia of unknown aetiology.
Men with azoospermia, severe oligozoospermia
, or an identifiable cause of infertility were excluded from the study, as well as couples where sterility was due to the female partner.
Nevertheless, it remains unknown whether the differences in ROS and capacitation levels after serum supplementation affect the fertilization potential of spermatozoa from patients with inadequate sperm parameters, such as oligozoospermia
, asthenozoospermia, and teratozoospermia.
