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...

Testicular sperm retrieval for the treatment of non-obstructive azoospermia requires the execution of an invasive procedure, with all its possible attending complications and subsequent long-term effects. This study suggests a new non-invasive approach for collection of spermatozoa in these patients: the extended sperm preparation (ESP). ESP consists of conducting a thorough microscopic search ...

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 ...

Cordyceps species have been traditionally used for the enhancement of sexual function, however, there is few direct evidence to prove this. We investigated the spermatogenic effect of Cordyceps militaris (CM) by supplementation with CM mycelium to subfertile boars. Seventeen Duroc and 12 Landrace boars (29 to 40 months old) were selected to feed with regular diet (control groups, n = 8 and 6, r...

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...

Total motile sperm count and DNA fragmentation Index are two parameters in analysis that have recently been used to determine the outcome of management cases male infertility. Motile Sperm Count is one values considered better than 2010 World Health Organization standard terms predictive value for success spontaneous ongoing pregnancy rate. High Fragmentation were associated with lower an incre...

Varicocele is a dilatation of the pampiniform plexus of the testicular veins, the varicocele repair has been shown to reverse a spectrum of effects contributing to men with impaired fertility, it can be treated either by surgical ligation or angiographic occlusion of the spermatic veins. The aim of this study is to compare the outcome of percutaneous varicocele embolization versus surgical liga...

STUDY QUESTION Are different dietary patterns associated with semen parameters in young men? STUDY ANSWER The consumption of a Prudent dietary pattern was significantly associated with higher progressive sperm motility and unrelated to sperm concentration and morphology. The consumption of a Western dietary pattern was unrelated to conventional semen quality parameters. WHAT IS KNOWN ALREAD...

The objective of this study was to assess fertilization, implantation and pregnancy rates in infertile patients with severe teratozoospermia [P (poor prognosis) pattern sperm morphology assessed by strict criteria] treated by in-vitro fertilization (IVF) using a high insemination concentration (HIC), or by intracytoplasmic sperm injection (ICSI). This was a retrospective cohort study performed ...

Objective Adiponectin and its receptors (AdipoR1 and AdipoR2), known as adiponectin system, have some proven roles in the fat and glucose metabolisms. Several studies have shown that adiponectin can be considered as a candidate in linking metabolism to testicular function. In this regard, we evaluated the correlation between sperm mRNA abundance of adiponectin and its receptors, with sperm moti...
