A follow-up study was performed to investigate the impact of the detection of a chromosome abnormality in infertile men who are candidates for intracytoplasmic sperm injection (ICSI) treatment. In this collaborative study between clinical genetics centres and fertility clinics in the Netherlands, 75 ICSI couples of which the male partners had a chromosome abnormality were included. All couples ...
Artificial insemination is a reproductive technology that uses the best male breeders. Successful artificial insemination is affected by several factors, one of the most important and most one is the availability of fertile sperm after the freezing-thawing process. The purpose of this study was to investigate the effect of different concentrations of naringenin after the freezing process. Sp...
The objective of the present study was to determine an optimum temperature and extender for short-term transport of canine ejaculated semen. There was no significant difference in the qualities of semen diluted with two kinds of extender, egg yolk Tris-citrate fructose (EYT-FC) or glucose (EYT-GC) extender, between the 2, 8 or 12 and the 4°C control groups during storage for up to 48 hr, while ...
Background: Prolonged alcohol abuse in men can cause testosterone deficiency and shrinkage of the testicles (testicular atrophy). This can lead to impotence, sterility and ‘feminisation’. When alcohol is broken down in the body, it may also interfere with normal sperm structure and movement. This study was designed to determine the effects of administration of alcohol on sperm quality, sperm ma...
BACKGROUND Poor sperm morphology is statistically associated with an increase in the incidence of chromosome abnormalities. Our aim was to examine the possible correlation between chromosomal aberrations and sperm morphology in the same cell. METHODS 12349 spermatozoa from 7 teratozoospermic and one globozoospermic patients, and from 3 fertile donors were analyzed using a system which scans f...
Diabetes mellitus contributes to male sexual dysfunction and infertility by modulating oxidative damage. To date, a number of studies have demonstrated antioxidant properties of Hibiscus sabdariffa Linn. This study was designed to investigate the effects of H. sabdariffa UKMR-2 variety on sperm functioning of streptozotocin-induced diabetic rats. Male Sprague-Dawley rats were allotted into four...
Pasundan cattle are one of the Indonesian domestic resources animal-genetic materials that need to be developed and conserved. The aims this study were evaluate characteristics sperm potential production frozen semen bulls. Ten bulls divided into two groups based on their fresh motilities. grouped motilities group A (70-79%) B (80-89%). Secondary data collected confirmed with primary data. volu...
The non-hormonal contraceptive, named RISUG (an acronym for Reversible Inhibition of Sperm under Guidance) has expected to provide a valuable addition to the current options of male contraception. The present study was conducted to determine the reproductive functional success, safety of vas occlusion by RISUG, and its reversal by dimethylsulphoxide (DMSO), followed by multigenerational (F1-F3)...
AIM The aim was to evaluate the effect of multiple oral administration of bisphenol A (BPA) for 28 days on seminal characteristic on mammal using Wistar rat as a model. MATERIALS AND METHODS Rats were randomly divided into five different groups having 6 male rats in each group. The doses chosen were 50, 200, and 600 mg/kg body weight for Groups III, IV and V, respectively, based on preliminar...
