Present study was conducted to evaluate the supplementation of different levels of antioxidant Butylated Hydroxyanisole (BHA) on the improvement cryopreservation of Mahabadi goat sperm. Four healthy Mahabadi goats (3-4 years) were used to collect semen samples by artificial vagina, once a week for five weeks during non-breeding season. Good quality samples were pooled and divided into five equa...

 Purpose: To investigate the in vitro effects of methanol leaf extract E. hirta (MLEEH) on motility, viability and morphology caprine spermatozoa.
 Methods: The effect MLEEH treatment (1.25, 2.5, 5, 10 20 mg per mL) sperm percentage total progressive abnormalities were evaluated at 1, 5 min post-treatment. Sperm revival test was used to evaluate reversibility incapacitation following...

Several gene expressions are related to the success of spermatogenesis. Protamine plays an important role in sperm DNA packaging, spermatogenesis, and quality. This study aimed isolate RNA from spermatozoa determine expression profiles protamine 1 (PRM1) 2 (PRM2). Six Pasundan bulls aged 5-8 years with a body weight 380 kg-430 kg were used for this study. The classified into group A (70%-79%) B...

Background: Infertility in men can be caused by decreased motility of spermatozoa. Electric cigarette smoke containing nicotine produce free radicals that cause a decrease sperm motility. Purple grape juice which contains flavonoids act as antioxidants increase the Objective: To prove effect administering purple on male Wistar rats exposed to electric smoke.Methods: This research is an experime...

Fresh and post-thaw parameters (motility, morphology and viability) of stallion epididymal spermatozoa that have been and have not been exposed to seminal plasma were evaluated, and directly compared to fresh and post-thaw parameters of ejaculated spermatozoa. Six sperm categories of each stallion (n=4) were evaluated for motility, morphology and viability. These categories were fresh ejaculate...

Background: Many studies are being conducted to improve the quality of bull sperm in storage conditions. It seems that increasing sperm membrane unsaturated fatty acids can enhance sperm quality. This study was aimed to investigate the effects of combination of omega- 3, 6, 9 fatty acids on characteristics of bovine chilled semen. Materials and Methods: Different levels of oil containing omega-...

Formaldehyde (FA), a ubiquitous environmental pollutant, has long been suspected of having male reproductive toxicity. However, FA male reproductive toxicity was inconclusive due to dearth of human studies. Therefore, we sought to investigate whether occupational exposure to FA affects semen quality. Semen quality including five conventional parameters and seven kinematics parameters were compa...

AIM The purpose of this study was to evaluate the semen profiles of bicycle taxi cyclists and healthy controls in Mangochi district, Malawi. METHODS Semen samples were collected from young bicycle taxi cyclists after two to three days of sexual abstinence. A control group, comprising young men who were not bicycle taxi operators also submitted semen samples. Samples were left to liquefy for 3...

Infertility affects approximately 15% of couples, and in about one-third the primary cause is a male factor. Patients undergoing infertility investigations frequently experience sexual dysfunction, which often is due to inadequate vaginal lubrication. This can lead to increased use of coital lubricants. The effects of such lubricants on sperm motility have not been widely studied, although sper...

Ejaculated bull spermatozoa were exposed to various concentrations of ouabain to ascertain the effect on membrane potential, intracellular concentrations of sodium and potassium and motility. Membrane potenital, measured by electrophysiological methods, decreased. Intracellular potassium decreased and intracellular sodium increased. Progressive motility decreased. In addition, the motility chan...
