Causes of azoospermia

We studied 50 male infertile patients, who were azoospermic on semen analyses. Most of these cases [60%] had untreatable lesions. Some hope of success is expected in spermatogenic maturational arrest, which constituted 26% of our cases. Duct obstruction which is considered favourable to surgical correction was encountered in only 12% of the patients. The other notable causes were primary testicular failure [18%] and sertoli cell [18%] syndrome

Causes of male infertility

We have studied 150 male patients presenting for infertility over a period of three years. After taking detailed history and through physical examination, required investigations were done. Unilateral or bilateral varicocele turned out to be the most common cause [27.3%] of infertility in these patients. Thirty one [20.7%] patients were infertile due to testicular failure. About 11% of the cases had inflammatory lesions. Four percent of the male infertile patients had ejaculatory duct obstruction while another 4% had congenital abnormalities. In a big population of these patients [27.3%] we were unable to determine any reason. The etiology of male infertility in our country is discussed with reference to similar studies from abroad

Fertility potential of semen

Semen specimens have been analysed in 50 men of proven fertility and 100 male partners of infertile marriages. Our results show that there was no statistically significant difference in volume, PH and liquefaction time in the ejaculates of both groups. The semen was however much superior in fertile fathers than in infertile men [p < 0.001], as regards sperm density, percent motility, motility in various grades and morphology. We conclude that sperm density, sperm motility and normal morphology are the main determinants of fertility potential
