Abstract

Background: Semen parameters, especially sperm count and motility have been said to be diminishing over time with implications for fertility and infertility treatment. Objective: The objective of this study was to study semen parameters 10 years apart and describe any observed change. Design: A retrospective study carried out at Nordica Fertility Centre, Lagos, Nigeria. Semen parameters of 100 consecutive men who sought fertility treatment on account of infertility in 2003 and semen parameters of 100 consecutive men who also sought fertility treatment at the center in 2013 on account of infertility were analyzed and compared. A paired t-test was performed to ascertain whether sperm counts have diminished over the last decade. The World Health Organization semen values were used as standard. Main Outcome Measures: They are sperm count, motility, and mean progressive motility. Results: The mean sperm count in the 2003 group was 34.6 × 106/ml (range: 0.1-105.0 106/ml) compared with 21.8 × 106/ml (range: 0.1-80.0 × 106/ml) in the 2013 group. The mean motility was 47.9% in the 2003 group and 45.3% in the 2013 group. The mean progressive motility in the 2003 group was predominantly graded as good (50% good, 44% fair, 2% poor, 4% no motility) while in the 2013 group, the predominant grade of mean progressive motility was fair (15% good, 81% fair, 4% poor). Normal morphology was more commonly seen in the 2013 group compared to the 2003 group. Mean semen volume was 2.7 and 2.6 ml in 2003 and 2013 groups, respectively. The mean difference in sperm count (mean = 12.8, standard deviation = 31.6, n = 100) was significantly >0 providing evidence that sperm counts have diminished in the last decade. Conclusion: There was a statistically significant 37% drop in mean sperm count and mean progressive motility worsened in the last decade. These may have far-reaching effects on infertility and its treatment. [ABSTRACT FROM AUTHOR]

Abstract

Education takes actual visible form in educational systems. They either are the work of states or are approved and supervised by them. No educational system can escape from the political community in which if operates. The system must reflect what the political community wants it to do. The system can set formally to change the community only if the community includes change of this kind among its aims. No doubt every educational system contains some germ of true education and is therefore likely to have side effects unexpected by and unwelcome to its sponsors. To this end, this paper takes a critical look into the influence of politics on the educational system in Nigeria. What good has emanated from the supposed symbiotic relationship between education and politics? What harm has politics unleashed on education? And what steps need be taken to straighten issues? Answers to the aforementioned and allied questions are the main focus of this write-up. Keywords: Politics, Education, Community, Symbiotic
