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...

Primary ciliary dyskinesia (PCD) is a rare, autosomal recessive disease with abnormalities in the structure of cilia, causing impairment of muco-ciliary clearance with respiratory tract infections, heterotaxia and abnormal sperm motility with male infertility. Here, with a comprehensive literature review, we report a couple with an infertility history of 9 years and three unsuccessful IVF treat...

Factors that affect sperm quality can include method of semen collection, conditions for capacitation and whether or not agglutination is present. Media and procedures for sperm washing can also impair or improve sperm function in assisted reproductive technologies. For example, the removal of seminal fluid through large volume washing is required to eliminate decapacitation activity of seminal...

Semen is usually collected from bulls by use of an artificial vagina (AV) or by electroejaculation (EE). Semen collected by EE is often more dilute and may appear to be less motile than that collected by AV, although total sperm per ejaculate and sperm viability should be essentially similar (assuming the EE collection has been successful and complete). As fresh semen is very susceptible to env...

The process of fertilization can’t be attributed only to the number of live, motile and normal sperm deposited within the female but especially to its functionality [1]. The hypoosmotic test or hypoosmotic test (HOST) is a functional test, by which the live sperm are subjected to an incubation in a hypoosmotic solution, the sperm with the functional membrane will allow the entry of water by osm...

MAIN FINDINGS An intriguing yet perplexing case report of a successful pregnancy and live birth with intracytoplasmic sperm injection using normal testicular sperm, after the finding of azoospermia in the semen analysis and discovering only tail stump abnormal sperm in the epididymis. Case hypothesis: A tail stump sperm defect of genetic origin was suspected. However, after obtaining normal tes...

background: use of cellular phones emitting radiofrequency electromagnetic field (rf-emf) has been increased exponentially and become a part of everyday life. this study aimed to investigate the effects of in vitro rf-emf exposure emitted from cellular phones on sperm motility index, sperm dna fragmentation and seminal clusterin (clu) gene expression. materials and methods: in this prospective ...

Sixty-five percent of the children of recent immigrants are low income. For these children, the challenges in academic, physical, emotional, and social development usually associated with economic insecurity are likely to be exacerbated by language barriers, the process of migration and acculturation, and restrictions on access to safety net programs. Two-thirds of children of low-income, recen...

BACKGROUND AND OBJECTIVE Freezing changes sperm integrity remarkably. Cryopreservation involves cooling, freezing, and thawing and all these contribute to structural damage in sperm, resulting in reduced fertility potential. Low-level laser irradiation (LLLI) could increase energy supply to the cell and cause reactive oxygen species reduction (ROS), contributing to the restoration of oxygen con...
