[Abnormal semen analyses in men undergoing premarital screening and in infertile couples in Butembo-Democratic Republic of Congo].

The purpose of this study was to determine the prevalence of spermogram abnormalities in men consulting for premarital screening and in infertile couples in Butembo. We conducted a retrospective descriptive study at the Graben University Diagnostic Center. The study population consisted of 890 male subjects aged 21-57 years, of whom 779 underwent prenuptial screening and 111 subjects fertility tests. The overall prevalence of spermogram anomalies in this population was 25.8%, corresponding to a total incidence of 22.9% of premarital consultants and 46,0% of males in infertile couples. Mean pH was: 7.22+/- 0.22. The average volume of semen collected was: 2.56 +/- 1.41 ml. Abnormalities were detected in all spermogram parameters, with a predominance of abnormalities in the same subject (86.5%), mainly in oligoasthenoteratozoospermia (44.8% of cases). Asthenozoospermia was the most common abnormality (90.9% of cases), followed by oligozoospermia (87.4% of cases), teratozoospermia (66.9% of cases), necrozoospermia (55.6% of cases), and azoospermia (10.4% of cases). This study highlights that the cytological profile of the spermogram of this population in Butembo is dominated by associations of anomalies. Other tests such as bacteriological examinations and biochemical marker assays are necessary, in order to identify the causes of abnormalities and to provide appropriate therapies.
