semen from six adult male black bengal goats (capra hircus) was collected to compare the fresh and frozen-thawed semen quality and investigate its relationship with the fertility. each collected samples was divided into two parts: one part of semen was used as fresh and another part was filled into 0.50 ml straws, sealed, cooled (5 ˚c) and equilibrated for freezing.in both cases, semen was dilu...

Metronidazole (MTZ) is a common antiparasitic and antibacterial drug. The drug and X-ray induced effects in mouse sperm count, sperm head abnormality and some oxidative stress parameters have been studied. Simultaneously the protective role of curcumin has been evaluated. MTZ, 40 mg/kg bw and 13.4 mg/kg bw × 3 days exposure induced abnormal sperm head and reduced total sperm count in Swiss albi...

BACKGROUND Macrocephalic or large headed sperm with multiflagella is a rare abnormality often associated with infertility. Sperm chromosomal abnormalities could be associated with this specific morphological abnormality. METHODS The cytogenetic content of large-headed sperm was assessed by dual and three-colour fluorescence in-situ hybridization in three patients carrying this specific morpho...

The generation of reactive oxygen species in diabetes is considered to be the major cause for the mutation related defects such as cancer, infertility etc. Glimepiride (Gmp) is a third generation antidiabetic sulphonylurea known to possess the antioxidant effect in streptozotocin (STZ) induced diabetes. In this study, the anti-mutagenic activity of Gmp (0.175, 17.5 and 175 mg/kg, po daily for 4...

OBJECTIVE To evaluate levels of sperm nuclear DNA damage in infertile men with normal and abnormal standard semen parameters. DESIGN Prospective study. SETTING Male infertility clinic. PATIENT(S) Ninety-two men seeking infertility treatment and 16 fertile volunteers. INTERVENTION(S) Standard semen analysis was performed according to the World Health Organization guidelines. MAIN OUTCO...

Sperm morphological analysis (SMA) is an essential step in diagnosing male infertility. Using images of human sperm cells, this research proposes a unique sequential deep-learning method to detect abnormalities semen samples. The proposed technique identifies and examines several components sperm. In order conduct study, we used the online Modified Human Morphology Analysis (MHSMA) dataset cont...

The present study was undertaken to know the seasonal infl uence on various seminal attributes in Murrah buffalo bulls. Data on 156 ejaculates of eight Murrah buffalo bulls (nearly 30 to 58 months) maintained under identical nutrition and management conditions were selected randomly from Artifi cial Breeding Complex, NDRI, Karnal, India, from May, 2006 to April, 2007. The information on 156 eja...

The effects of Tahitian noni juice (TNJ), vitamin C and vitamin E on male reproductive functions in cyclophosphamide-treated wistar rats were compared. Thirty five male wistar rats with mean body weight of 180 ± 24.3 g were randomly divided into five groups. Group one were treated with cyclophosphamide (50 mg/kg, i.p.) while, group two were treated with TNJ (10 ml/kg, i.p.) and cyclophosphamide...

We report the first 16 cases of a new sperm abnormality which we call 'easily decapitated spermatozoa defect'. This was discovered during intracytoplasmic sperm injection (ICSI) in couples with unexplained infertility. Semen analysis was normal, but minimal micromanipulation for ICSI resulted in decapitation of the spermatozoon during immobilization. For some oocytes the head and tail were inje...

We carried out this study to assess the quality of semen regarding seasonal and geographical variability Murrah buffalo breeding bull in Nepal. aimed access seme n murrah considering help standardize producing protocol concern. A total eight bulls were used. Semen collection was done at once week two ejaculations considered an interval 30 minutes during Summer (June August), Autumn (September N...
