Association Between Urinary Parabens and Sperm Quality in Nigerian Men: A Case-Control Study.

Background: Parabens, which are chemicals used as preservatives in cosmetic and pharmaceutical products, have been reported to be associated with low sperm quality in animal and human models. Despite the high exposure of men to paraben-containing products in Nigeria, there are no known studies that investigate the association of parabens with sperm quality in the country.

Objective: To determine the association of urinary levels of metabolites of parabens with sperm count and quality.

Association of Urinary Mycotoxins with Sperm Quality: A Case-Control Study in Southern Nigeria.

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.

Pregnancy in Older Women: Analysis of Outcomes in Pregnancies from Donor oocyte Fertilization.

Background: As the number of older women attempting to conceive through donor oocyte- fertilization (DO-IVF) rises, their safety in pregnancy needs to be judiciously considered.

Aims: This study aims to review the obstetric and perinatal outcomes of pregnancies achieved by DO-IVF.

Study Setting And Design: A retrospective study design conducted at a private health facility with services for assisted reproduction and gynecologic endoscopy.

Experience with Hysteroscopy in a Private Specialist Hospital in Nigeria.

Background: Hysteroscopy is a standard method for the evaluation and treatment of various gynecological disorders. Its availability and accessibility are limited in our setting owing to resource constraints. Nevertheless, the utilization is on the increase mostly in private health institutions in Nigeria and as an adjunct in infertility management.

Randomized controlled trial of labor outcomes with action line placement at 2 hours versus 4 hours on the partograph.

Objective: To evaluate whether treatment of slow labor progress among term nulliparous women using a 2-hour partograph action line reduces the incidence of prolonged labor versus a 4-hour action line.

Methods: Randomized controlled trial of nulliparous women with a term singleton, non-macrosomic, cephalic fetus in labor attending a university hospital in Nigeria (2008-2015). For labor supervision, women were randomly assigned to the 2-hour (n=320) or 4-hour (n=320) partograph action line group.
