Background: Despite the evidence of declining sperm counts worldwide and the increasing prevalence of male infertility, there has been limited documentation of the potential causes and risk factors for male infertility. With limited methods of primary treatment of male infertility, understanding the causes and risk factors will pinpoint specific lines of prevention. Objective: We reviewed published studies on causes and risk factors for male infertility and identify gaps in the literature enabling more focused research and innovations. Design/Setting: The study was a scoping review. The review included studies on the causes and risk factors of male infertility published in scientific/academic publications. It was not limited to any region or date. The following databases were searched: Cumulative Index to Nursing and Allied Health Literature, Wiley online, HINARI, Science Direct, PubMed/Medline, Google Scholar, African Journals Online, and the WHO Repository. In total, 1295 articles were identified. After removing 357 duplicates, 938 articles were screened, and 71 articles were identified for inclusion, while 60 articles met the inclusion criteria. Results: Four broad causes and risk factors of male infertility identified were 1) biological/physiological/genetic causes, 2) behavioral/lifestyle risk factors, 3) environmental factors, and 4) socio-demographic risk factors. However, no substantive results on actual causes under each category were identified, leaving gaps for further research and experimentation. Conclusion: The results indicate limited knowledge of the actual causes of male infertility in published studies. The gaps in knowledge that need to be bridged to enable a fuller understanding of the actual causes of male infertility were highlighted.

Despite the adoption of Maternal and Perinatal Death Surveillance and Response (MPDSR) by Nigeria’s Federal Ministry of Health to track and rectify the causes of maternal mortality, very limited documentation exists on experiences with the method and its outcomes at institutional and policy levels. The objective of this study was to identify through the MPDSR process, the medical causes and contributory factors of maternal mortality, and to elucidate the policy response that took place after the dissemination of the results. The study was conducted at the Central Hospital, Benin between October 1, 2017, and May 31, 2019. We first developed a strategic plan with the objective to reduce maternal mortality by 50% in the hospital in two years. An MPDSR committee was established and the members and all staff of the Maternity Department of the hospital were trained to use the nationally approved protocol. All consecutive cases of maternal deaths in the hospital were then reviewed using the MPDSR protocol. The results were submitted to the hospital Management and its supporting agencies for administrative action to correct the identified deficiencies. There were 18 maternal deaths in the hospital during the period, and 4,557 deliveries giving a maternal mortality ratio (MMR) of 395/100,000 deliveries. This amounted to a seven-fold reduction in MMR in the hospital at the onset of the project. The main medical causes identified were obstetric hemorrhage (n = 10), pulmonary embolism (n = 2), ruptured uterus (n = 2), eclampsia (n = 1), anemic heart failure (n = 1) and post-partum sepsis (n = 2). Several facility-based and patient contributory factors were identified such as lack of blood in the hospital and late reporting with severe obstetric complication among others. Response to the recommendations from the committee include increased commitment of hospital managers to immediately rectify the attributable causes of deaths, the establishment of a couples health education program, mobilization and sensitization of staff to handle pregnant women with great sensitivity, promptness and care, the refurbishing of an intensive care unit, and the increased availability of blood for transfusion through the intensification of blood donation drive in the hospital. We conclude that the results of MPDSR, when acted upon by hospital managers and policymakers can lead to an improvement in quality of care and a consequent decline in maternal mortality ratio in referral hospitals.

Across several African countries, birth preparedness and complication readiness (BPACR) among pregnant women is poor. The practice of BPACR, though improving in recent years, is not commensurate with the knowledge available to pregnant women. Maternal health indices remain sub-optimal. This study evaluates the determinants of this “know-do’ gap among women receiving antenatal care at a secondary health facility in Benin City, Nigeria. A cross-sectional study involving 427 pregnant women was conducted between October and December 2020 using a structured interviewer-administered questionnaire. The prevalence of knowledge and practice were described, and the determinants of BPACR practice evaluated using bivariable (chi-square) analysis and multivariable ordinal logistic regression with post-estimation predictive margins analysis. About 77% of respondents had good birth preparedness practice. Multivariable regression revealed that respondents with poor knowledge and moderate knowledge of components of BPACR had statistically significant lower odds (OR:0.05 (95% CI: 0.02-0.13) and 0.10 (95% CI: 0.03-0.30) times, respectively) for greater practice of BPACR when compared to those with good knowledge. Respondents with poor knowledge of danger signs had statistically significant lower odds (OR: 0.08 (95% CI: 0.03-0.26) for greater practice of BPACR when compared to those with good knowledge. But predictive margins analyses demonstrates that knowledge, though critical to practice, is insufficient to optimize practice. The optimum number of danger signs women need to know to improve practice may be between eight to ten. Beyond this number, practice may not change significantly. Other predictors of BPACR practice include income level, parity, gravidity, and residential settings. The number of antenatal clinic visits had no statistically significant correlation with BPACR practice. Interventions to facilitate practice at the community level may be helpful to improve outcomes and bridge the know-do gap with respect to BPACR within the study context.

Background: Data in Nigeria suggests a high level of dissatisfaction among women attending maternity care in health facilities due to long wait times, disrespectful care, and poor attention by healthcare personnel. Objective: To examine the effectiveness of a multifaceted intervention in improving self-reported indicators of maternal healthcare satisfaction by women who use referral facilities in two regions of Nigeria. Method: The design was quasi-experimental and consisted of two intervention facilities and two control facilities. The interventions included strategic planning, staff re-training, a computerized appointment system, health education/feedback, maternal death reviews and surveillance, and advocacy. A random sample of 2262 women was selected (1205 in the intervention sites and 1057 in the two control sites) to respond to a 24-item questionnaire on service satisfaction as they exited the health facilities. Adjusted Poisson and binary regression analyses were used to assess and compare proportions of reported satisfaction by women between the intervention and control sites. Results: Women in the intervention sites were 54% more likely than those in control sites to report overall satisfaction with services. They were significantly less likely to report inadequate security arrangements in accessing the health facilities (p < .1); and three times more likely to agree that health workers were extremely thorough and careful in attending to them (p < .1). Conclusion: The interventions had positive effects on improving women’s satisfaction with care. The findings from this study have implications for the design and implementation of interventions that address women’s concerns relating to the provision of care and consequently improve service utilization.

The objective of this study was to determine the association between mycotoxins and the quality of spermatozoa in Nigeria. We designed a prospective case-control study involving 136 men diagnosed with reduced sperm count and quality in five infertility clinics in southwest Nigeria and 154 normal fertile controls. Sperm analysis was conducted in accordance with the recommendations of the World Health OrganizationWHO, while Liquid Chromatography–Mass Spectrometry was used to assay three metabolites of mycotoxins (zearalenone, ochratoxin A, and deoxyvinelol) in the urine samples of cases and controls. The data were analysed with descriptive statistics and non-parametric linear regression. The results showed no overall significant difference in levels of these metabolites between the cases and control groups. In contrast, higher levels of zearalenone and ochratoxin A significantly decreased sperm motility in the cases. Similarly, an increase in the level of ochratoxin A decreased sperm morphology in the unadjusted model in the cases. We conclude that exposure to mycotoxins reduces the quality of spermatozoa (motility and morphology) in Nigerian men but may have no effect on sperm count. Efforts to reduce the exposure of men to mycotoxins are important interventions to improve sperm quality and reduce the prevalence of male infertility in the country.

Background: Eclampsia causes maternal mortality in Nigeria. This study presents the effectiveness of multifaceted interventions that addressed institutional barriers in reducing the incidence and case fatality rates associated with eclampsia. Methods: The design was quasi-experimental and the activities implemented at intervention hospitals included a new strategic plan, retraining health providers on eclampsia management protocols, clinical reviews of delivery care and educating pregnant women and their partners. Prospective data were collected monthly on eclampsia and related indicators from study sites over 2 y. The results were analysed by univariate, bivariate and multivariable logistic regression. Results: The results show a higher eclampsia rate (5.88% vs 2.45%) and a lower use of partograph and antenatal care (ANC; 17.99% vs 23.42%) in control compared with intervention hospitals, but similar case fatality rates of <1%. Overall, adjusted analysis shows a 63% decrease in the odds of eclampsia at intervention compared with control hospitals. Factors associated with eclampsia were ANC, referral for care from other facilities and older maternal age. Conclusion: We conclude that multifaceted interventions that address challenges associated with managing pre-eclampsia and eclampsia in health facilities can reduce eclampsia occurrence in referral facilities in Nigeria and potential eclampsia death in resource-poor African countries.
