background: globozoospermia is a rare (incidence of 0.1% among andrological patients) and poorly understood condition, but a severe disorder in male infertility. this case report detailed the course of treatment and protocol of a patient with type 1 globozoospermia using intracytoplasmic sperm injection (icsi) and oocyte activation by calcium ionophore, which yielded conception and birth of a h...

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...

Semen was collected from 50 men occupationally exposed to carbaryl (1-naphthyl methyl carbamate) in a produciton plant for durations of 1 to 18 years and compared to semen from a control group of 34 unexposed, newly-hired workers. Employment, fertility, health, personal data, and blood samples were collected for each individual. Semen samples were analyzed for changes in sperm count, morphology...

Objective
 There are not enough reports about whether liquefaction time and semen pH values related to sperm functions. Therefore, this study aimed evaluate there is a relationship between major parameters. 
 Material Methods
 The data were divided into groups as normal abnormal compared in terms of times. samples also grouped according acidic (8.0) liquefying (≤30 min.) slow (&g...

Sperm analysis of 21 patients taking sulphasalazine for inflammatory bowel disease revealed that 86% had abnormal semen analysis and 72% had oligospermia.

BACKGROUND One of the semen quality parameters use to determine fertility is the percentage of sperm that express normal morphology. Sperm head morphometry is also correlated with fertility. The objectives of this study were 1) to investigate the sperm morphology and normal sperm head morphometry of Thai native crossbred stallions, and 2) to compare our results with the characteristics of prove...

background: the role of oxidative stress in endosulfan-induced reproductive toxicity has been implicated. this study was performed to evaluate the possible protective effect of vitamins e and c, against endosulfan-induced reproductive toxicity in rats. methods: fifty adult male sprague–dawley rats were randomly divided into five groups (n=10 each). the groups included a control receiving vehicl...

Introduction: Infertility affects millions of people reproductive age worldwide. Male infertility may be caused by a number different factors including problems in the ejection semen, absence or low levels sperm, abnormal morphology and movement sperm. Environmental lifestyle also have meaningful impact on male system. Fertility care should include prevention, diagnosis treatment disorder. That...

The aim of this study was to investigate the possible protective role of lycopene on cisplatin (CP)-induced spermiotoxicity using quantitative, biochemical and histopathological approaches. Adult male Sprague-Dawley rats were randomly divided into four groups. The control group received physiological saline; animals in cisplatin group received only cisplatin; pre-treatment group received a 10-d...
