Antichlamydia antibodies and sperm quality among male partners of infertile couples ins Nigeria.

Background: The impact of Chlamydia trachomatis on semen quality has been studied with varied results. Aim: To determine the prevalence of antichlamydial antibodies and their relationship with sperm quality among male partners of infertile couples in Enugu, South-East Nigeria. Materials and Methods: It was a cross-sectional study of infertile male partners of couples attending infertility clinics at the University of Nigeria Teaching Hospital (UNTH) Ituku-Ozalla, Enugu, Nigeria. Their sera were assayed for antichlamydial antibodies, and semen analysis and culture were done for each participant. Results: Two hundred and eighty-two (282) male partners of infertile couples were studied. Infertility was commoner among participants aged 40 years or more (45.1%) and was mainly of the "primary type" (62.1%). Antichlamydia antibody was detected in 156 (55.3%) participants and was significantly associated with sperm quality (P = 002; OR = 2.294; 95% CI = 1.36-3.88). Overall, 81 (28.7%) had abnormal sperm quality. The sperm count, progressive motility, and vitality were significantly lower in participants with abnormal sperm quality than those with normal sperm quality (P < 0.001) while morphology, volume, and liquefaction time did not differ significantly (P > 0.05). Staphylococcus aureus was the predominant organism isolated from culture (122/282, 43.3%) while Streptococcus species were the least (4/262, 1.4%). There was significantly more Staphylococcus aureus isolated from the semen of participants that were seropositive to antichlamydial antibodies than those that were seronegative (80/156, 51.3% vs. 42/126, 33.3%; OR = 2.105; 95% CI = 1.30-3.42; P = 0.003). Conclusion: The prevalence of antichlamydial antibodies among male partners of infertile couples in Enugu, Nigeria is high and there is a significant association with sperm quality, sperm count, and bacterial isolates in seminal culture. Male partners of infertile couples in Enugu should be screened for antichlamydial antibodies and appropriate treatment offered wherever indicated. There is a need for increased public awareness and advocacy campaigns on the impact of Chlamydia infection on male factor infertility. This primary preventive measure may help in reducing the burden of Chlamydia infection and male factor infertility.

Duration and determinants of inter-birth interval among women in Enugu, south-eastern Nigeria.

The difference in fertility levels of any given two societies has a relationship with the interval between births. We determined the duration of inter-birth interval and the determinants of short inter-birth interval in Enugu, Nigeria. Questionnaires were administered to a cross-section of 420 women consecutively recruited from the family planning and antenatal clinics of two hospitals in Enugu metropolis. The mean age was 30.9 ± 5.1 (range 20-44) years. The median inter-birth interval was 21.5 months and the prevalence of modern contraceptive use among respondents was 18.1%. Women's age of 25 years or less, duration of breast-feeding of 10 months or less, and non-use of modern contraceptives had strong association (p < 0.05) with short inter-birth interval. The mean inter-birth interval in Enugu is short. Future child spacing campaign in Enugu should target the encouragement of longer breast-feeding practices and increased uptake of modern contraception among our women.
