Lead level in seminal plasma may affect semen quality for men without occupational exposure to lead
BACKGROUND Infertility affects approximately 10-15% of reproductive-age couples. Poor semen quality contributes to about 25% of infertile cases. Resulting from the direct effect on testicular function or hormonal alterations, heavy metals exposure has been related to impaired semen quality. The objective of this study was to assess the level of lead in the seminal plasma in men without occupati...
متن کاملSperm 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 کاملChronic environmental exposure to lead affects semen quality in a Mexican men population
BACKGROUND Male infertility is affected by several factors. Lead is one of the heavy metals more bioavailable than usually modifies the sperm quality in humans. OBJECTIVE The aim of this study was to establish the role of lead in semen quality in environmentally exposed men. MATERIALS AND METHODS Semen and blood samples were obtained from two groups: the exposed group (EG=20) and the non-ex...
