Men with infertility associated with 2.3 fold higher risk of death. The factors evaluated were semen volume, sperm concentration, sperm motility, total sperm count, total motile sperm count. Those that have 2 or more positive parameters were associated with increased death compared to those with normal semen analysis.

retrospective cohort finds mild but significant relationships b/t BMI and total Testosterone, Testosterone:Estradiol and Estradiol alone. BMI was inversely correlated with Testosterone and the T:E2 ratio; but directly correlated with E2 alone. There was also a negative correlation with sperm concentration, motility and morphology.

Cause and effect cannot be taken from this study. However, TNF-alpha is known to disrupt testicular function, in this case the study found decreased sperm motility, lower Testosterone levels, and increased LH and FSH at baseline. Improvement was seen after anti-TNF-alpha therapy. The point of this study should be why the elevated TNF-alpha and attack there.

Vitamin D plays role in healthy Testes function. This signaling occurs through genomic and non-genomic signaling pathways. Testosterone production is influenced, sperm motility and spermatogenesis is influenced.

These results support the notion that occupational lead exposure at currently acceptable levels has a small adverse effect on sperm quality, especially sperm motility, and that this effect is at least partially reversible
