Objectives: The aim of the present study was to evaluate protective effect of royal jelly on sperm parameters, testosterone level, and malondialdehyde (MDA) production in mice. Materials and Methods: Thirty-two adult male NMRI mice weighing 30±2 g were used. All the animals were divided into 4 groups. Control group: received saline 0.1 ml/mouse/day orally for 30 days. Royal Jelly group (RJ): re...

his recently published cross-sectional study that included 99 men from Massachusetts General Hospital Fertility Center, Boston, MA, USA, reports that a high intake of saturated fats was inversely associated with sperm concentration and total sperm count and a high intake of omega-3 polyunsaturated fats (PUFAs) was positively associated with sperm morphology. Although the study is based upon a h...

PURPOSE Epilepsy has an impact on the reproductive system. Males with epilepsy have lower fertility rates, hypo-sexuality and reduced potency compared with the general population. Anti-epileptic drugs and epilepsy itself are thought to be responsible for this reduced fertility. LEV is a second-generation anti-epileptic agent with low incidences of both adverse effects and drug-drug interactions...

Unexplained infertility requires that more sensitive and mechanism-based biomarkers should be developed and used independently of or in addition to conventional semen parameters for an infertility diagnosis. In the present study, semen samples were collected from young men participating in the Male Reproductive Health in Chongqing College students (MARCHS) cohort study in the follow-up stage in...

Previous studies of the associations of measures of occupational lead exposure with measures of semen quality and infertility among male workers have produced conflicting results. The current study was undertaken to examine these associations among a population of workers with a broad range of measures of current and historical lead exposure. Ninety-seven lead-exposed workers from a South Afric...

The effect of sperm count per insemination dose was evaluated on fertility and litter size at birth. In the first experiment, 124 receptive multiparous does were inseminated with 16, 4, 2 and 1 million spermatozoa. Does were slaughtered 12 days after insemination and the number of implanted embryos were recorded. Does inseminated with 16 or 4 million sperm showed no differences in pregnancy rat...

Canine seminal plasma contains antioxidant enzymes to protect sperm against internally generated ROS. These enzymes are removed from seminal plasma during the process of cryopreservation. The freezing/thawing process can cause some morphological and functional changes via ice crystallization and osmolality imbalance. The present study was conducted to evaluate the effects of curcumin supplement...

This study was undertaken to investigate whether there is relationship between seminal plasma transferrin and seminal parameters which included sperm count, motility and morphology. The study included 100 male subjects in the age group of 23-41 yrs including 7 proven fertility, 6 post-vasectomised and 87 subjects were of idiopathic infertility. Estimation of seminal plasma transferrin concentra...

This study investigated the effects of 30-day exposure to tobacco smoke (TS), smokeless tobacco (ST), and nicotine on reproductive parameters and oxidative biomarkers in prepubertal and adult male rats. Sperm motility was reduced by 77.5 and 89.0% in TS and ST exposed prepubertal rats and 71.1 and 86.4% in adult rats, respectively. Sperm count was also reduced by 64.7 and 89.9% in prepubertal r...
