Phthalates exposure of Chinese reproductive age couples and its effect on male semen quality, a primary study

submitted by doneildeoz 3 years and 4 months ago
Phthalates are suspected of having adverse effects on androgen-regulated reproductive development in animals and may be toxic for human sperm. The purposes of our study were to investigate the general exposure of a Chinese reproductive age cohort to these ubiquitous pollutants and to assess their potential effect on semen quality.Six phthalate metabolites, monomethyl phthalate (MMP), monoethyl phthalate (MEP), monobutyl phthalate (MBP), monobenzyl phthalate (MBzP), mono-2-ethylhexyl phthalate (MEHP), and mono-2-ethyl-5-oxohexyl phthalate (MEOHP) were measured in spot urines of 15 individuals recruited from a Chongqing, China, reproductive institute. The questionnaire and clinical data were evaluated, and the correlations of phthalate exposure and. Research highlights: In this report, we investigated 6 phthalate mono esters in urine of a reproductive age cohort from Chongqing, China. To our knowledge, this is the first study based on Chinese cohort to investigate the reproductive age phthalate exposure and the relationship between phthalate exposure and semen quality. The preliminary results suggest that the subjects are commonly exposure to phthalate, and the phthalate exposure (MBP, MEP, and MMP) may play a potential role in reproduction age males’ semen quality on these Chinese men. In view of human reproductive health and current widespread use of phthalate in China as well as our preliminary results, the report will be a valuable reference for the further environmental health studies.

Environmental toxicants viz lead or cadmium and phthalate esters (di(2-ethylhexyl) phthalate [DEHP], dibutyl phthalate [DBP], and diethyl phthalate [DEP]) widely found in different environmental strata are linked to deteriorating male reproductive health. The objective was to assess the relationships between the seminal lead, cadmium, and phthalate (DEHP, DBP, DEP) concentrations at environment...

Phthalates which are widely used, are ubiquitous in the environment and in some human tissues. It is generally accepted that phthalates exert their toxic action by inhibiting Leydig cell synthesis of testosterone, but in vitro studies have also shown anti-androgenic effects at the receptor level. Some cross-sectional studies have shown inverse associations between urinary levels of phthalates a...

Anogenital distance and the risk of prostate cancer
submitted by kotchin212 1 year and 11 months ago - Topic: Health
In animals, anogenital distance has been shown to be related to the action of fetal androgens, and exposure to chemicals such as dioxins that exhibit antiandrogenic activity results in shorter distances in male rats. In studies conducted in children, anogenital distance has been associated with endocrine disruptors such as phthalates. Studies conducted in young adults found that a shorter anosc...


Brief maternal exposure of rats to the xenobiotics dibutyl phthalate or diethylstilbestrol alters adult-type Leydig cell development in male offspring
submitted by lesdo 1 year and 7 months ago - Topic: Health
Maternal exposure to estrogenic xenobiotics or phthalates has been implicated in the distortion of early male reproductive development, referred to in humans as the testicular dysgenesis syndrome. It is not known, however, whether such early gestational and/or lactational exposure can influence the later adult-type Leydig cell phenotype. In this study, Sprague–Dawley rats were exposed t...

Association between chemical pattern in breast milk and congenital cryptorchidism: modelling of complex human exposures

During the past four decades, there has been an increase in the incidence rate of male reproductive disorders in some, but not all, Western countries. The observed increase in the prevalence of male reproductive disorders is suspected to be ascribable to environmental factors as the increase has been too rapid to be explained by genetics alone. To study the association between complex chemical ...

Cryptorchidism and hypospadias are common genital birth defects that affect 2-9% and .2-1% of male newborns, respectively. The incidence of both defects shows large geographic variation, and in several countries increasing trends have been reported. The conditions share many risk factors, and they are also interlinked to the risk of testis cancer and poor semen quality. Testicular Dysgenesis Sy...
