The major cause of infertility among black Africans is traditionally a
ttributed to a female factor and few reports are available on the male
factor. This study analyzed the clinical and seminal data obtained fr
om a population of 1726 suspected infertile African men evaluated from
July 1985 to June 1991. The possible cause of infertility was judged
on the results of first semen analysis. Of these men, 49% were seconda
rily infertile and 36% had previously received treatment for a urethra
l discharge. Varicocoeles were present in 183 cases (11%) and 11% had
serological evidence of previous exposure to syphilis. Azoospermia was
present in 152 patients (9%), 5% had polizoospermia, 45% had hyposper
mia (<2 mL) and 9% (>6 mL) had hyperspermia. In 70% of patients a poss
ible contributing male factor for infertility was found. It would appe
ar that the male factor contributed significantly to infertility, and
evaluation of the black African male can therefore be regarded as a re
warding venture.
