This study examined demographic characteristics of men with infertility were referred to the Shariati Hospital Infertility Clinic. Materials and Methods: This is a cross-sectional study. 200 eligible patients were enrolled with written consent Face-to-face interview...

Background: Sperm cryopreservation is recommended to preserve male fertility for cancer patients or other medical conditions at risk of sperm decline. Whether motility and viability recovery rates vary depending on the requiring poorly known. We report here 24-year experience our semen bank. Methods: Motility were evaluated in 1973 collections from with various 67 donors, results related basal ...

background: lead is an industrial heavy metal that can decrease sperm motility. objective: the aim was to investigate the protective effects of calcium against lead on motility of spermatozoa. materials and methods: in total 40 adult male swiss white mice were randomly divided into 5 groups (control, lead of 1st wk, lead of 2nd wk, lead/calcium of 1st wk and lead/calcium of 2nd wk). the lead gr...

AIM The objective of this research is to report parameters for breeding soundness evaluation, semen extension, and cryopreservation in Rusa timorensis. MATERIALS AND METHODS Seven healthy stags were chosen for semen collection using an electroejaculator. The collections were performed twice in a breeding season between February and June 2016. Samples were collected between 2 and 3 weeks inter...

The chamois of Abruzzi (Rupicapra pyrenaica ornata) has been classified as endangered by the World Union for Conservation. The objective of this study was to analyze seasonal differences in the characteristics of various male reproductive organs and in semen quality. The study was conduced during 2004 in the reserve of Lama dei Peligni (Italy) on three chamois males aged between 2 and 5 years. ...

SUMMARY We used ocular motility recordings to identify the characteristics of a rare combination of conjugate, horizontal jerk, and pendular nystagmus in a 9-year-old boy. The clinical diagnoses were amblyopia, left esotropia, congenital nystagmus, and an apparently uniocular pendular nystagmus that mimicked spasmus nutans. Ocular motility recordings revealed an unusual latent/manifest latent n...

This study was aimed at evaluating the relationship between body mass index, sex hormones and semen characteristics in male adults. 120 male adults aged 20 to 50 years who consented to participate in the study were used. Serum samples collected from each subject were analyzed for luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin (PRL), progesterone, estradiol and testoster...

Cimetidine is effective drugs on male reproductive system by its effect semen characteristic or parameters such as sperm motility, morphology and count, also cimetidine sexual hormones, were testosterone, FSH LH. In this investigation, 20 rats randomly classified into two groups, Control group(G1): This group contain 10 receiving normal saline group( G2): 100mg/kg. B.W. from group, during the p...

A flower-shaped micromotor driven by gliding bacteria named Mycoplasma mobile (M. mobile) has been developed by using two-photon microfabrication. This micromotor is autonomously rotated by the collisions of M. mobiles gliding randomly on a substrate. The flower-shaped rotor is derived from the unique motility of M. mobile. We examined the motility characteristics of M. mobile using walls with ...
