sperm chromatin structure, semen quality and lead in blood and seminal fluid of infertile men
background: exposures to lead above the threshold value of 50–60 μg/dl have been linked to diminished semen quality parameters. worldwide, the lead exposure has been diminished during the last years. therefore, it has become of a great concern to examine the effects of lead exposures on semen quality at low levels of exposure. objective: to evaluate the effect of low level (<20 μg/dl) blood lea...
متن کاملThe effect of rhFSH on Sperm DNA Fragmentation and sperm parameters in Oligozoospermia Infertile Men
Background: One of the main causes of male infertility is the negative effects of oxidative stress. Follicle-stimulating hormone (FSH) plays an essential role in spermatogenesis, as well as in the maintenance of sperm DNA integrity. This study aimed to determine whether the recombinant human follicle-stimulating hormone (rhFSH) treatment of sperm parameters could positively affect sperm DNA and...

متن کاملTrace elements in seminal plasma of men from infertile couples
INTRODUCTION An analysis of lead, zinc, cadmium and other trace elements in semen of men from infertile couples was performed to determine the association between abnormal semen parameters and enviromental or occupational exposure to some trace metals. MATERIAL AND METHODS Presence of manganese, cobalt, nickel, copper, zinc, molybdenum, cadmium, tin and lead was measured in seminal plasma of ...
متن کاملLevels of plasma ACTH in men from infertile couples.
INTRODUCTION Emotional stress connected with work or, for example, depressive reaction to infertility, is one of frequent causes of decreased quality of semen. An objective examination of this factor is difficult because stress depends also on patient's emotionality. One of the ways to study this problem is evaluating the relation between ACTH level and selected semen parameters. MATERIAL AND...
