RÉSUMÉ
Background: Male infertility is the condition in which a male is unable to establish pregnancy in a fertile woman over 12 months of unprotected sexual intercourse. In this study, the prevalence of male-factor infertility and some associated risk factors in Port Harcourt, Rivers State was carried out. Methods: The study design was a case-controlled randomized one, in which semen specimens were collected from case and control groups randomly amongst males visiting urology/fertility clinics by masturbation after 3 days of abstinence. A total of 276 males indicated interest to participate in study of which 193 male subjects were recruited. Results: The result showed that 20.8% were azoospermic, 27.4% were oligospermic, 23.7% were asthenozoospermic, 27.9% oligoasthenozoospermic, 15.1% teratozoospermic, 19.4% asthenoteratozoospermic, and 12.9% oligoasthenoteratospermic. Furthermore, the microbial quality of the semen assessed indicated the prevalence of scanty, moderate, and heavy growth as 12.5%, 9.3%, and 7.3% respectively. Likewise, organisms isolated and identified were Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, and mixed growth of staphylococcus aureus, and Escherichia coli with a prevalence of 18.2%, 5.6%, 2.0%, 1.04%, and 2.6% respectively. Civil servants had the highest prevalence of 20.8% followed by artisans with 11.9%. The prevalence of primary and secondary infertility was observed to be 30.1% and 18.1% respectively. Conclusions: Male-only factor infertility is on the increase and occupations that are accompanied by prolonged sitting, sedentary work style, or working in or close to high-temperature sources as seen in civil servants and welders (artisans) were observed to be more prone to male-only factor infertility.
RÉSUMÉ
Background: Diabetes and hypertension which are metabolic conditions are becoming more common and prevalent in the world. Prolonged rise of blood sugar levels, is a hallmark of diabetes, a metabolic condition caused by problems with insulin production, insulin resistance or both while hypertension is the persistent high blood pressure in the arteries. Leptin is a hormone that inhibits appetite, reduces fat storage in adipocytes and aids in the regulation of energy balance hence implicated in diabetes and insulin resistance. Thus, can metabolic state affects its level in the serum. Methods: The study population is two hundred and forty (240) subjects that are residents of Port Harcourt aged between 30-70 years. Sixty subjects were used as the control, sixty subjects were diabetes, the other sixty subjects were hypertensive while the remaining sixty were subjects with both hypertension and diabetic mellitus. An enzyme-linked immunosorbent assay (ELISA) method was used to quantitatively measure leptin levels in the serum sample, glycated haemoglobin were determined quantitatively using sandwich immunodetection and blood pressure was measured using mercury sphygmomanometer. Results: The data generated were statistically analysed using Graph Pad Prism version 9.0.2. The results showed no significant difference in leptin levels in diabetics, hypertensive and subjects having both diabetes and hypertension when compared with the control subjects having none of these metabolic disorders (p =0.4166). Conclusions: Our results shows that leptin levels in the population were relatively within the reference ranges both for males (0.5-12ng/ml) and females (0.5-15ng/ml). It clearly shows that metabolic conditions (diabetes or hypertension) does not affect leptin levels in serum.
