in this study, chromosome analyses were performed on 70 infertile azoospermic and oligospermic (<20 million/ml) men, and also cultures of peripheral blood lymphocytes by high resolution banding method were analysed as well. it is revealed 8 (11.43 percent) men with chromosomal abnormality. there were 31.4 percent patients with azoospermia and 68.6 percent with oligospermia from several thousand...

Background: Since the deleterious effects of reactive oxygen species (ROS) during sperm cryopreservation can be overcome by antioxidants, post-thaw human sperm quality may perhaps profit from adding antioxidants to the extender media prior to cryopreservation. This study evaluated the effects of different concentrations of Trolox supplementation to cryo-protective media on post-thaw motility an...

OBJECTIVE In sever oligospermia; one of the paths used for surgical sperm retrieval (SSR) is to extract sperm via a testicular biopsy. The aim of our study is to determine the reliable time interval between testicular biopsy and intracytoplasmic sperm injection (ICSI) procedure in order to obtain optimumsperm parameters (count, motility and normal morphology). MATERIALS AND METHODS This cohor...

A cross sectional study of sperm motility index (SMI) in normozoospermic and oligoasthenoteratozoospermic males was undertaken to find correlation between sperm concentration and SMI. Two-hundred subjects with impaired fertility potential were screened for the routine seminogram parameters along with SMI using sperm quality analyzer (SQA IIB) to find out the SMI in the population of central Ind...

Whether the 370-371insACA, 494T>C, and 1423C>T haplotype in ubiquitin-specific protease 26 (USP26) gene is associated with male infertility is controversial. To clarify this issue, we conducted a meta-analysis based on the most recent studies. Eligible studies were screened by using PubMed and Embase. Pooled odd ratio (OR) with 95% confidence interval (CI) was calculated with fixed effect model...

OBJECTIVE To investigate the influence of consanguineous marriage on male factor infertility in Lebanon, where rates of consanguineous marriage remain high (29.6% among Muslims, 16.5% among Christians). DESIGN Clinic-based, case-control study, using reproductive history, risk factor interview, and laboratory-based semen analysis. SETTING Two IVF clinics in Beirut, Lebanon, during an 8-month...

BACKGROUND Vasectomy techniques have been the subject of relatively few rigorous studies. The objective of this analysis was to compare the effectiveness of two techniques for vas occlusion: intraluminal cautery versus ligation and excision with fascial interposition. More specifically, we aimed to compare early failure rates, sperm concentrations, and time to success between the two techniques...

is devoted to factors which might have a deleterious effect upon apparently normal spermatozoa, with chapters on spermigration in the female secretions, special technics in spermatozoal study, the longevity of spermatozoa in vivo, the effect of temperature on the survival of spermatozoa in vitro, and abnormalities in the female which inhibit impregnation. There is a discussion of artificial ins...

The present study evaluated the conventional sperm parameters and the seminal concentration of CD45pos cells (pan-leukocyte marker) of infertile patients with idiopathic oligoasthenoteratozoospermia (OAT). The patients were arbitrarily divided into three groups treated with recombinant follicle-stimulating hormone FSH: α (Group A = 20 patients), recombinant FSH- β (Group B = 20 patients), and h...
