Introduction: Modern couples are inclined to postpone conception as a result of societal pressures and expectations during the last several decades. The impact age on spermatogenesis in men is not much studied. While there no known limits at which can father children, implications Advanced Paternal Age (APA) poorly understood. Aim: To assess relationship between advancing aberrant sperm paramet...

We have observed that sperm quality parameters indicative of spermatozoa hyperactivation such are lower "linearity" and "straightness", and as showed by this research "elongation", were more pronounced in patients with normal spermiogram compared to the group of men with reduced sperm motility who were undergoing routine in vitro fertilisation. The research encompassed 97 men diagnosed with nor...

The objective of the present study was to investigate the effects of the direct addition of pentoxifylline (PF) to the ejaculates of men with poor sperm quality before freezing on post-thaw sperm motility, viability, acrosome integrity, and agonist-induced acrosome reaction. Semen specimens from 16 infertile men with impaired sperm count and motility (oligoasthenozoospermia) were divided into t...

INTRODUCTION The exact causes of the decline in semen quality are not yet known, environmental factors have been considered to play an important role. Lead (Pb) and Cadmium (Cd) are two of the well-known reproductive toxicants to which humans are exposed occupationally and environmentally and can lead to negative effects on the testicular functions. The aim of this study was to evaluate lead an...

OBJECTIVE To investigate, in men presenting with recurrent pregnancy loss (RPL), the prevalence of sperm autosome and sex chromosome aneuploidy. DESIGN Retrospective study. SETTING Male infertility clinic. PATIENT(S) A total of 140 men with RPL provided semen samples, and five normozoospermic controls provided 140 semen samples for comparison. Recurrent pregnancy loss, documented in the f...

Background: Oligoasthenospermia (OAS) is a condition characterized by low sperm count associated with low sperm motility. Medical treatment is not known in allopathic system for treatment of oligoasthenospermia. Homeopathic medicine is effective in more than 95% patients. Oxidative stress and decreased antioxidant levels have been projected as a potential factors involved in the pathophysiology...
