Male factor subfertility ranges from 30 – 50 % of the causes. It can be diagnosed using a very simple non – invasive test "Semen analysis". So it is imperative to get this test done before considering any complex investigations on the female partner and before commencing any subfertility treatment.
Semen analysis WHO 2010 Criteria
≥ 1.5 ml
Low volume could indicate: incomplete sample, partial retrograde, obstruction or androgen deficiency.
≥ 15 x 106 M/ml
A very low sperm count may indicate a partial/full blockage or testicular failure. May recommend a referral to fertility specialist or andrologist for investigation.
Total sperm count (per ejaculate)
≥ 39 x 106M
(Concentration x volume). This is not directly reported in the report but will be commented only if significant.
Total motility (progressive + non progressive)
Motility is temperature dependent and samples which take over an hour to reach the lab will be recommended a repeat.
Culture and sensitivity may be advisable if cell number exceeds this.
MAR test (anti-sperm antibody test)
≥ 50% IgG&IgA
Caused by trauma to testicles/prior surgery. Common in vasectomy reversals. Causes agglutination of spermatozoa
