BACKGROUND The intracytoplasmic sperm injection procedure ending with total fertilization failure is very distressfull event for both the clinician and the patient. OBJECTIVE The aim of this study was to identify independent factors which could be used to identify total fertilization failure before the day of intracytoplasmic sperm injection. MATERIALS AND METHODS This was a retrospective s...

Intracytoplasmic sperm injection has revolutionised the management of male infertility. We report two cases that demonstrate the successful application of this technology in Nigeria in the management of both oligospermia and azoospermia. The first case relates to the treatment of a 31-year-old woman who required intracytoplasmic sperm injection of her husband's sperm for the treatment of both t...

Oocytes inseminated by intracytoplasmic sperm injection using fresh ejaculated or freeze-dried rhesus macaque sperm showed similar activation, sperm aster assembly, and male-female pronuclear apposition rates.

BACKGROUND In its 1993 report the Canadian Royal Commission on New Reproductive Technologies challenged the effectiveness of in vitro fertilization for severe male infertility. To address the Commission's concern, the authors compared the relative effectiveness of in vitro fertilization combined with intracytoplasmic sperm injection for severe male infertility and conventional in vitro fertiliz...

We compared the retrieval efficiency of single- (direct follicular aspiration) and double-lumen-needle (attained with follicular flushing) procedures in normal-responder IVF-intracytoplasmic sperm injection cycles. This prospective randomized study did not demonstrate a beneficial effect of double-lumen needle retrieval compared with single-needle retrieval in normal-responder IVF-intracytoplas...
