PURPOSE To evaluate the predictive power of luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone, testicular biopsy histology and male age were evaluated with respect to the success of sperm retrieval in a microdissection testicular sperm extraction (microTESE) procedure, pregnancy and live birth rates. MATERIALS AND METHODS We examined the data of 131 infertile men with...

OBJECTIVE To evaluate the effect of vaginal lubricants Pre-Seed, FemGlide, Astroglide, and Replens on human sperm motility and chromatin integrity. DESIGN Prospective, comparative, in vitro study. SETTING Andrology laboratory at tertiary care hospital. PATIENT(S) Thirteen normozoospermic donors. INTERVENTION(S) Semen samples from 13 subjects were incubated in human tubal fluid media (HT...

BACKGROUND Density gradient is the preferred technique for sperm processing for ART. However, no study has examined sperm quality using different processing media simultaneously and under identical conditions. Therefore, we evaluated semen quality following sperm preparation by three commonly used commercially available density gradient media in a well-designed controlled trial. METHODS We ob...

OBJECTIVE To investigate the effectiveness of intracytoplasmic sperm injection (ICSI) using testicular sperm as a strategy to overcome infertility in men with high sperm DNA fragmentation (SDF). DESIGN Prospective, observational, cohort study. SETTING Private IVF centers. PATIENT(S) A total of 147 couples undergoing IVF-ICSI and day 3 fresh ETs whose male partner has oligozoospermia and h...

In vitro fertility assessment using fluorescent technique is a better predictor of fertility status of bulls as compared to traditional semen quality assessment techniques, therefore, the study was planned to assess in vitro fertility status of bulls based on conventional and fluorescent techniques. Seventy-three ejaculates were collected from 12 Murrah buffalo bulls maintained at Artificial Br...

A morphological, biochemical and physiological study has been made of the effects of chloroquine-diphosphate (a membrane stabilizer) on the preservation of buffalo spermatozoa in five modified dilutors designated here as Al’ A2’ A3, A4 and CAW. In almost all the five dilutors, there was significant (p< 0.01) progressive increase in the percentage of sperm abnormalities and the release of enzyme...

Objective Improvement in sperm density and motility after varicocelectomy have been widely reported for men with oligoasthenoteratospermia (OAT),However the value of varicocelectomy in azoospermic men remain controversial.In this study we have evaluated the outcome of microsurgical varicocelectomy in nonobstructive azoospermic (NOA) men with clinical varicocele in five years in royan institute....

Received: Revised: Accepted: April 22, 2013 July 30, 2013 July 31, 2013 The present study was aimed to investigate the association of scrotal circumference (SC) with sperm production and semen quality in Sahiwal bulls. Mature semen donor bulls (n=76), 3 to 5 years old, were divided into three groups according to SC: GI, GII, and GIII with 28-30, 31-35, and >35 cm, respectively. Semen was collec...

STUDY QUESTION How do live birth rates compare after intracytoplasmic sperm injection (ICSI) for men with obstructive azoospermia when using sperm derived from testicular sperm extraction (TESE) versus microsurgical epididymal sperm aspiration (MESA)? SUMMARY ANSWER Our study suggests that proximal epididymal sperm (from MESA) result in higher live birth rates as compared with testicular sper...

BACKGROUND In patients with transient azoospermia, few sperm may be found in the ejaculate. We investigated the outcome of ICSI in patients with transient azoospermia. METHODS Records of patients with transient azoospermia referred during a 42 month period were reviewed. If only immotile sperm were found, the sample was incubated with 30% human serum albumin (HSA) before motility re-assessmen...
