Background: Rosa damascene constitutes showed different properties like antimicrobial, anti asthma and bronchitis, anti depression, and skin protection. Objective: Survey of effect of rose water extract on male mice reproductive parameter. Methods: In first part of experiment, adult male mice (Balb/c) 25 - 30 gram were divided into three groups; control, 10 and 20 ml/kg/day rose water. Intera...

AMP-activated kinase (AMPK), a protein that regulates energy balance and metabolism, has recently been identified in boar spermatozoa where regulates key functional sperm processes essential for fertilization. This work's aims are AMPK identification, intracellular localization, and their role in human spermatozoa function. Semen was obtained from healthy human donors. Sperm AMPK and phospho-Th...

Objective Crocin, a carotenoid isolated from Crocus sativus L. (saffron), is a pharmacologically active component of saffron. Nicotine consumption can decrease fertility in males through induction of oxidative stress and DNA damage. The aim of this study is to determine the effects of crocin on reproductive parameter damages in male mice exposed to nicotine. MaterialsAndMethods In this experime...

This study evaluated night and day semen collection regimes in Holstein and Brahman bulls (four bulls of each breed) that were collected weekly, each during a morning and a night collection. Ejaculates (n=64) were obtained via artificial vagina over 4 weeks. The first collection of each week alternated between night and day. Two collection teams were employed. Bull behavior parameters included ...

tau.amegroups.com © Translational Andrology and Urology. All rights reserved. The andrological factor is implicated in more than 40% of couples attending infertility clinics. Considering that standard semen analysis only poorly predicts the outcome of fertilization and pregnancy in couples including assisted reproduction attempts as it only examines sperm parameters such as sperm concentration,...

The relationships between testis size, hormone secretion and sperm production were studied during the spring (December) and autumn (May) in rams of two breeds with different breeding seasons and body weights (Corriedale and Australian Merino) maintained on native pastures and under natural photoperiods in Uruguay. Blood samples were collected at 20-min intervals during a 260-360-min period in 1...

UNLABELLED Male infertility is one of the most stressful factors of couples, being present in about 40% cases. It is usually caused by a low number of sperm (oligozoospermia) or poor sperm motility (asthenozoospermia). The sperm motility is used as an indicator of semen quality and male infertility. To the impairment of male reproduction health can contribute genetic, nutritional and environmen...

BACKGROUND Obesity is rapidly becoming a worldwide epidemic that affects children and adults. Some studies have shown a relationship between obesity and infertility, but until now it remains controversial. Thus, the aim of the present study was to investigate the effect of high-fat diet-induced obesity on male reproductive parameters. METHODS In a first experiment, male Wistar rats were fed a...

Background: Artificial insemination (AI) has been used for increasing genetic potential of animals in production while application of AI has been restricted in buffalo due to low freezing ability and fertility of frozen-thawed buffalo spermatozoa. So improvement in buffalo sperm cryopreservation may enhance the breeding programs of this valuable farm animal. Semen processing is one of the major...

Background: Sperm cryopreservation has been associated with over production of reactive oxygen species (ROS). Buffalo spermatozoa are susceptible to ROS inducing damages due to insufficient level of cytoplsmic antioxidant along with high amount of poly unsaturated fatty acids composition in membrane structure. Therefore, appropriate antioxidant in buffalo cryopreservation extender would reduce ...
