Introduction. To investigate the association of high Body Mass Index (BMI) with semen parameters and reproductive hormones in men of reproductive age. Setting. The Saudi Center for Assisted Reproduction. Method. This study was conducted during the period from February 2009 to February 2011. Subjects were exposed through medical history evaluation as well as physical examination. BMI was calculated. Two semen samples about 1 week apart were taken from each participant by masturbation after 2–5 days of abstinence. The samples were assessed according to the WHO Criteria. Blood samples (5 ml) were withdrawn; centrifuged and the resulting sera were preserved at −4 degrees Centigrade. Serum FSH, LH, PRL, and Testosterone levels were estimated by the ELISA method. Results. There was no significant correlation between BMI and any of semen and hormonal parameters. There was significant negative correlation between age and total motility. Only the advanced paternal age has shown significant association with low motility (P = 0.007). Conclusion. Our study showed a significant effect of aging on sperm motility and concentration.

BackgroundThe available evidence on the role of obesity and body mass index (BMI) on male infertility has been controversial or inconclusive to some extent.ObjectivesThe aim of this study was to investigate the role of BMI on some male-fertility laboratory indicators both among infertile and fertile men in an Iranian population.Methods and materialsA total of 159 male patients who had lived as a partner in an infertile couple for at least 1 year, after regular reproductive activity in their married life, and who sought infertility consultation, were investigated. BMI was assessed, and a morning blood sample was taken assessing serum levels of testosterone, sex hormone-binding globulin, prolactin, luteinizing hormone (LH), follicle-stimulating hormone, and estradiol. Semen-analysis parameters were also measured.ResultsIn this study, it was found that the likelihood of oligospermia was increased at higher BMI values. Obese men were found to be 3.5 times more likely to have oligospermia than those with normal BMI. BMI was not found to be associated with mean numeric values of the semen-analysis parameters, including sperm count, sperm morphology, and sperm motility. BMI was not significantly correlated with some hormone levels, such as LH, prolactin, and LH/follicle-stimulating hormone ratio. However, a statistically significant association was observed between BMI and estradiol (P < 0.01), sex hormone-binding globulin (P < 0.001), and also the testosterone/estradiol ratio (P < 0.001). A different pattern of associations in this study was observed when the associations between BMI and sexual hormone levels were compared between fertile and subfertile/infertile men.ConclusionThe association explored between BMI and some sexual hormones and semen characteristics, as well as different patterns of this association between fertile and subfertile/infertile men, will be of help to broaden our understanding of the effect of obesity on some male reproductive physiologic characteristics among fertile and infertile men.

“…The deviation from the ideal weight disturbs the hormonal system. In women, the pathologic low or high bodyweight is associated with anovulation [7]. In the intercellular septa of fat tissue cytochrome 450 aromatases convert androstendion to oestron and testosterone to 17-ß-oestradiol; therefore, oestrogene domination occurs in obese women.…”

& A total of 274 men (aged: 26 AE 4.9 years) with normozoospermia were enrolled into this study. Their body mass index (BMI: kg=m 2 ) varied between 17 and 39. According to BMI, the patients were divided into four groups: Group 1: 17-20, Group 2: 20.1-25, Group 3: 25.1-30 and Group 4: 30.1-39. Twenty-nine subjects were found in the first, 96 in the second, 91 in the third and 58 men in the fourth group. Sperm concentration was significantly lower in the obese group (29 Â 10 6 =ml, p < 0.05) than in the group of BMI 17-20, 20-25 and 25-30. In advance, in the obese group, sperm count continuously decreased with aging. We conclude that obesity is associated with a lower sperm count in case of normozoospermia.
