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.

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.

In vitro fertilization at a public hospital in Nigeria.

Objective: To assess the results of an in vitro fertilization program newly established within a conventional infertility program at a university hospital in Nigeria.

Methods: From June 1, 2007, to June 30, 2011, following unsuccessful conventional treatments, 600 couples were offered in vitro fertilization with (if needed) intracytoplasmic sperm injection in batches of 30 couples. The outcomes measured were duration of ovarian stimulation and rate of ovarian hyperstimulation syndrome; numbers of follicles aspirated, oocytes retrieved, oocytes fertilized, and embryos transferred; and clinical pregnancy rate.

Efficacy of intermittent preventive treatment with sulfadoxine-pyrimethamine on placental parasitemia in pregnant women in midwestern Nigeria.

Objective: To assess the effect of intermittent preventive treatment with sulfadoxine and pyrimethamine (IPT-SP) on placental parasitemia and maternal and perinatal outcome.

Methods: We compared placental malaria parasitemia during pregnancy and pregnancy outcome in 2 groups of women receiving antenatal care at University of Benin Teaching Hospital. One group was prophylactically treated with IPT-SP and the other was not treated.

Knowledge and perception of emergency contraception among female Nigerian undergraduates.

Context: The reproductive health hazards of unintended pregnancies and unsafe abortions are well documented. The potential of emergency contraceptives to prevent unwanted pregnancy in developed countries has been described, but in Nigeria, the awareness about the method is poor and no study has looked at efficacy.

Methods: Between September and October 2001, a randomly selected sample of female undergraduate students at the University of Benin, Nigeria, were surveyed about their demographic information, sexual history and contraceptive use, and their awareness and knowledge of emergency contraception.
