This study explored the correlation between sperm ultrastructure in infertile patients with abnormal sperm morphology and DNA damage. Three unusual sperm morphologies were selected for the experimental group namely case 1 (95% headless sperm), case 2 (98% headless sperm), and case 3 (100% headless sperm), and the control group consisted of 2 subjects (20 and 15% headless sperm). For case 1, the...

OBJECTIVES To evaluate the presence of hormonal abnormalities and fertility disorders in patients with chronic kidney disease (CKD) awaiting renal transplantation. METHODS From September 2009 to April 2011 all male patients with CKD awaiting kidney transplantation were investigated. The following tests were performed: semen analysis, serum concentration of testosterone, SHBG, LH, FSH and prol...

OBJECTIVE To test whether sperm with abnormal head morphology are more likely to undergo DNA damage and/or chromatin modification during the process of freeze-thawing. DESIGN In this prospective study, the semen samples from forty-four men attending the infertility clinic were included. Samples were divided into aliquots to allow direct comparison of fresh and frozen spermatozoa from the same...

OBJECTIVES Environmental exposure to chemicals has been considered a potential factor contributing to deteriorated semen quality. However, previous literature on exposure to air pollution and semen quality is inconsistent. We therefore investigated the health effects of short-term and long-term exposure to fine particulate matter (PM2.5) on semen quality in Taiwanese men from the general popula...

Effect of Temulawak (Curcuma xanthorrhiza) Extract on Sperm Counts, Morphology, and Motility Nicotine-Induced Mice

background: the most frequent physical finding in infertile men is varicocele, in which one of the mechanisms that can affect seminal parameters is oxidative stress. objective: our study aimed, for the first time, to compare the efficacy of recombinant human follicle-stimulating hormone (rhfsh), human chorionic gonadotropin (hcg) and human menopausal gonadotropin (hmg) on sperm parameters and f...

Standardized sperm concentration and volume:volume extension were compared as dilution rates for canine semen freezing. Six proven stud dogs were submitted to two seminal collections by manual stimulation. Semen was evaluated and extended in tris plus egg-yolk and glycerol according to two different dilution rates. The first one was based on a standardized sperm concentration of 200x10 spermato...

The assessment of the percentage of spermatozoa having an 'ideal' morphology using so-called strict method is the method recommended in the latest edition of the World Health Organization (WHO) laboratory manual for semen analysis. This recommendation is a result of the statistical association between 'ideal' sperm morphology and fertility, and of the current general belief that sperm morpholog...

The semen samples of 1,110 (one thousand, one hundred and ten) Igbo males attending infertility clinic, aged between 30-50 years were collected and analyzed. The specimens were collected and analysed in the microbiology laboratory of the University of Nigeria Teaching Hospital (UNTH) Enugu, Eastern Nigeria. The standard method of masturbation after 3-5 days of prior abstinence from sex before s...

cyclophosphamide (cp) is one of the anti-neoplastic drugs. despite its numerous clinical applications, it has devastating effects on the testicles and declines the sperm quality in treated patients. this study was aimed to investigate the protective effect of crocin in improving the toxicity induced by cp in reproductive system. in this study, 24 male adult mice (6 to 8 weeks) were randomly div...
