Despite the prevalent clinical applications of cisplatin, serious toxic side effects comprising reproductive toxicity confine its therapeutic efficacy. Thus, the current study explored the possible protective effect of captopril and telmisartan against cisplatin-induced testicular damage in rats. Captopril (100 mg/kg) and telmisartan (10 mg/kg) were orally administered for 15 days, whereas cisp...

Background To evaluate predictive factors of successful microdissection-testicular sperm extraction (MD-TESE) in patients with presumed Sertoli cell-only syndrome (SCOS). MaterialsAndMethods In this retrospective analysis, 874 men with non-obstructive azoospermia (NOA), among whom 148 individuals with diagnosis of SCOS in prior biopsy, underwent MD-TESE at Department of Andrology, Royan Institu...

In 220 consecutive patients with non-obstructive azoospermia, sperm retrieval was attempted by a combination of conventional and microdissection testicular sperm extraction (TESE). For sperm retrieval, 2-3 conventional biopsies were performed followed by a microdissection TESE in cases of negative conventional biopsies. During the surgery, the vasculature of the testis was assessed using the op...

OBJECTIVE In sever oligospermia; one of the paths used for surgical sperm retrieval (SSR) is to extract sperm via a testicular biopsy. The aim of our study is to determine the reliable time interval between testicular biopsy and intracytoplasmic sperm injection (ICSI) procedure in order to obtain optimumsperm parameters (count, motility and normal morphology). MATERIALS AND METHODS This cohor...

BACKGROUND Diabetes mellitus has a variety of structural and functional effects on the male reproductive system. Diabetes results in reduced sperm parameters and libido. The present study aims to investigate the effects of royal jelly (RJ) on reproductive parameters of testosterone and malondialdehyde (MDA) production in diabetic rats. MATERIALS AND METHODS This experimental study was conduct...

BACKGROUND Testicular torsion due to oxidative stress results in infertility and testicular damage which can be preventable an important health problem worldwide. AIM The purpose of the present study was to investigate the changes of malondialdehyde (MDA), total antioxidant status (TAS), total oxidant status (TOS) levels; histopathological alterations; morphology, concentration and motilities...

BACKGROUND To evaluate predictive factors of successful microdissection-testicular sperm extraction (MD-TESE) in patients with presumed Sertoli cell-only syndrome (SCOS). MATERIALS AND METHODS In this retrospective analysis, 874 men with non-obstructive azoospermia (NOA), among whom 148 individuals with diagnosis of SCOS in prior biopsy, underwent MD-TESE at Department of Andrology, Royan Ins...

Objective: To analyze the causes, clinical features and t r ea tment ou tcomes in pa t i en t s w i th nonobstructive azoospermia (NOA) and different severity of hypospermatogenesis (HS). Methods: This is a retrospective study from our reproductive clinic. Data of history, physical findings, serum hormone profiles and genetic studies were collected. The severity of HS was subdivided into three ...

Background: Pentoxifylline (PX) is a methyxanthin derivative that influences the sperm motion characteristics. In general, PX has been reportedly effective in preserving sperm motility in vitro, also when administered orally to the asthenozoospermic patients. Objective: The main objective of this prospective clinical trial study was to rule out the effect of oral administration of PX on sperm p...

A comprehensive study is presented of a series of 124 infertile men undergoing testicular sperm retrieval for intracytoplasmic sperm injection (ICSI). In this study we correlated the histological changes observed in the testicular tissue with the results of the wet preparation and the outcome after ICSI using testicular spermatozoa. In all patients with normal spermatogenesis and hypospermatoge...
