in order to evaluate the effects of phenytoin on the reproductive system of rats in detail, 60 male rats were divided equally into 6 groups: 1-5 received 10 mg/kg/day phenytoin ip for 1,2,3,4 and 5 weeks, respectively. however, group 5 did not receive any phenytoin for the last 5th week. the control group (group 6) did not receive any treatment. the results revealed that phenytoin does not have...

Background: Sperm storage via freezing has been useful for men who have difficulty masturbating during assisted reproductive technology (ART) programs and before impotency caused by chemotherapy, vasectomy, and other procedures. Studies were undertaken to evaluate the extent of cryoinjury to both semen and sperm after repeated freezing and thawing in oligozoospermic and normozoospermic samples ...

In this study, sperm characteristics (motility parameters and ionic composition of seminal plasma) and effect of ions on motility (duration of motility of sperm and percentage of motile spermatozoa) and fertilization capacity (fertilization rate, hatching rate, survival rate and larvae length) were investigated in Ctenopharyngdon idella. The longest duration of motility obtained in solution con...

AIM To study whether additional measurements of motility characteristics of spermatozoa by computer assisted semen analysis (CASA) were more sensitive indicators of reduced semen quality than estimates of percentages of motile, rapid or progressive cells. METHODS Intermittent scrotal insulation was applied to 6 rams for 16 h per day for 21 days or to 2 of these for 12 h per day for 28 days in...

BACKGROUND The incidence of overweight and obesity in men of reproductive ages is rising, which may affect fertility. Therefore, this study aims to assess the associations between BMI, central adiposity and sperm parameters in men of subfertile couples. METHODS Ejaculate volume (ml), sperm concentration (millions per ml), percentage of progressive motile and immotile spermatozoa and total mot...

BACKGROUND In order to provide a reference for infertile men, we defined normal values of semen quality in a population of fertile men, using computer-assisted semen analysis (CASA) before and after sperm separation. Additionally, we investigated the relationship between semen quality and time to pregnancy (TTP). METHODS AND RESULTS Semen samples were obtained from 315 proven fertile men. The...

Purpose: This study sought (i) to investigate the relationship between Postwash total motile sperm count and Postwash percentage motile sperm in predicting successful intrauterine insemination and (ii) to determine the minimal Postwash total motile sperm count required to achieve pregnancy with intrauterine insemination. Methods: Five hundred four women, who underwent 1636 intrauterine insemina...

In the present study, bull sperm in the first and second ejaculates were divided into subpopulations based on their motility characteristics using a cluster analysis of data from computer-assisted sperm motility analysis (CASA). Semen samples were collected from 4 Japanese black bulls. Data from 9,228 motile sperm were classified into 4 clusters; 1) very rapid and progressively motile sperm, 2)...
