Classification of the semen of the male partners of infertile Nigerian couples.
Semen samples from 500 Nigerian male partners of infertile couples were classified according to their sperm counts and progressive motility. 74.15% of these men were normozoospermic while 16.19, 5.57 and 4.09% were azoospermic, necrozoospermic and asthenozoospermic, respectively. The degree of oligozoospermia was mild (35.88%), severe (23.22%) or very severe (40.90%). The classifications of two consecutive samples per patient collected two weeks apart were highly correlated. Results show that in over 70% of these infertile couples, infertility was due to a female factor, the absence of which therefore has to be established before semen analysis. Some socioeconomic factors in infertility were also implied.
