Purpose: The purpose of this Guideline is to provide guidance to clinicians who offer vasectomy services. This guidance covers pre-operative evaluation and consultation of prospective vasectomy patients; techniques for local anesthesia, isolation of the vas deferens and occlusion of the vas deferens during vasectomy; post-operative follow-up; post-vasectomy semen analysis and potential complica...

INTRODUCTION Investigations play a pivotal role in the workup for infertility. The results must be interpreted carefully as these assess dynamic function. Evidence-based guidelines are useful in the selection of appropriate tests. MATERIALS AND METHODS A review of current evidence-based guidelines for the investigation and management of the infertile couple is undertaken. RESULTS The main a...

PURPOSE Our aim was to evaluate the effect of neat semen vitrification on human sperm vital parameters and DNA integrity in men with normal and abnormal sperm parameters. MATERIALS AND METHODS Semen samples were 17 normozoospermic samples and 17 specimens with abnormal sperm parameters. Semen analysis was performed according to World Health Organization (WHO) criteria. Then, the smear was pro...

A retrospective analysis of sixty one prospective donors who visited the cryobank in person from August 1999 to December 2001 was done. The study evaluated the acceptance rate of prospective semen donors and semen characteristics in order to assess the fertility potential of the supposedly normal population of young men. The outcome of the various screening processes--history taking, infection ...

BACKGROUND The utility of blood reproductive endocrine biomarkers for assessing or estimating semen quality was explored. METHODS A cross-sectional study of 47 DDT exposed malaria vector control workers was performed. Tests included blood basal and post gonadotrophin releasing hormone (GnRH), luteinizing hormone (LH), follicle stimulating hormone (FSH), testosterone, sex hormone binding globu...

AIM This study was aimed at investigating semen parameters that vary most in samples of healthy donors undergoing stressful examination period. METHODS Samples were left to liquefy in an incubator at 37 degrees C, 5% CO2 for 30 minutes before volume was measured. Concentration and motility parameters were measured by means of computer assisted semen analysis (CASA) using Sperm Class Analyzer ...

AIM The goal was to compare the effects of three different sperm preparation media on sperm motility, viability, and DNA integrity of semen samples from normozoospermic men. METHODS A total of 15 normozoospermic males were included in the study. The semen analysis (SA) was performed in accordance with the WHO guidelines (2010). After SA, each sample was divided into three aliquots, and swim-u...

Two hundred and fifty seven individuals from 16 African and Indian andrology laboratories attended several -semenology workshops from 1997 to 2013. The external quality control programme in Africa indicated the ability of participants to maintain the technology skills following a hands-on training. The pre-training sessions of the workshops indicated a total lack of knowledge how to perform a s...

AIM The objective of this study was to evaluate the effects of different concentrations of soybean lecithin (SL) and virgin coconut oil (VCO) in Tris-based extender on chilled and frozen-thawed bull semen quality parameters. MATERIALS AND METHODS A total of 24 ejaculates were collected from four bulls via an electroejaculator. Semen samples were diluted with 2% VCO in Tris-based extender whic...
