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...

background: while traditional semen parameters are of significant clinical value, total fertilization failure in ivf cycles is not uncommon. sperm function testing such as; hamster egg penetration test has severed limitations as a clinical test. the aim of this study was to evaluate the predictive value of semen parameters by using of intracellular calcium [ca2+]i increase in response to proges...

BACKGROUND Pentoxifylline (PX) is a methyl xanthine derivative that influences the sperm motion characteristics and L-carnitine (L-C) is an amino acid that is naturally produced in the body. In general, separate administration of PX and L-C has been reported to be effective on preserving sperm motility in vitro, and also when is consumed orally by the Idiopathic oligoasthenoteratozoospermia (IO...

INTRODUCTION Somatic chromosomal rearrangements that occur in infertile males are thought to be one of the major genetic factors influencing male infertility. The objective of this retrospective study was to evaluate sperm parameters in a group of patients with balanced translocations. MATERIAL AND METHODS We analyzed semen of 84 balanced somatic translocation carriers [35 Robertsonian transl...
