The present study aimed to compare the in vitro fertilizing capacity of frozen-thawed ejaculated and epididymal spermatozoa in order to standardize the semen preparation protocol for camel in vitro fertilization (IVF). Semen samples were collected from 7 Dromedary camels by means of artificial vagina (AV). Ten cauda epididymes were obtained from slaughtered adult camels, isolated, incised and r...

Background: Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have an adverse effect on health, leading to reduced life expectancy and/or increased health problems such as infertility and sub fertility. Lipid peroxidation contributes to the damage of the sperm plasma membrane and result to infertility. In this study effects of Antioxidants (E, C, ...

Background: Treating infertility doesn’t merely deal with advanced medical procedures. The effects of most of herbal drugs is not clearly established on fertility potential. One of this herbal formula is NOFODA comprising of Orchis mascula, Tribulus terrestris, Amygdalus communis, Ficus carica, Allium ampeloprasum, Nasturtium officinale and pollen of Phoenix dactylifera. In this study, the effe...

Cryopreservation is an efficient way to store spermatozoa and plays a critical role in the livestock industry as well as in clinical practice. During cryopreservation, cryo-stress causes substantial damage to spermatozoa. In present study, the effects of cryo-stress at various cryopreservation steps, such as dilution / cooling, adding cryoprtectant, and freezing were studied in spermatozoa coll...

Although the role of the epididymis, a male accessory sex organ, in sperm maturation has been established for nearly four decades, the maturation process itself has not been linked to a specific molecule of epididymal origin. Here we show that Bin1b, a rat epididymis-specific beta-defensin with antimicrobial activity, can bind to the sperm head in different regions of the epididymis with varied...

BACKGROUND Diabetes mellitus characterized by hyperglycaemia could affect sperm quality as a result of increased oxidative stress. This study was performed to investigate the effects of red palm oil (RPO), aqueous rooibos tea extracts (RTE) as well as their combination (RPO + RTE) on sperm motility parameters in streptozotocin-induced diabetic rats. MATERIALS AND METHODS Diabetes was induced ...

A gradual increase in the concentration of Ca2+ from anterior to the posterior region was observed when mono- and divalent cations were estimated in different segments of the epididymis in wall lizard. Na+ and K+ levels increased from anterior to middle segment but declined significantly in the posterior segment. However, no significant difference in the levels of Mg2+ was observed in various s...

This study investigated the correlation between sperm motion parameters obtained by a computer-assisted semen analyzer and levels of reactive oxygen species in unwashed semen. In total, 847 patients, except for azoospermic patients were investigated. At the time of each patient's first consultation, semen parameters were measured using SMAS™ or CellSoft 3000™, and production of reactive oxygen ...

The aim of this study was to cryopreserve and evaluate frozen-thawed semen parameters. Electroejaculator was used to collect semen from six bucks. Semen samples were divided into two parts. In one part, seminal plasma was removed and was not in the other one. Both semen sample parts were extended with egg-yolk Tris extender. Semen was thereafter cryopreserved in straws using liquid nitrogen. Da...

Purpose To determine whether reactive oxygen species (ROS) in semen samples could be measured with the Monolight™ 3010 Luminometer. Methods Using the Monolight™ 3010 Luminometer, the ROS was measured in the unprocessed semen samples of infertile male patients, as well as the luminescence of 190 semen samples. The samples were classified as "luminescence-detectable" (n = 89) and "luminescence-...
