2012 study that shows a slight uptick in sperm count/concentration in Danish men. However, as the conclusion states, on 25% have optimal sperm quality. When you look at the numbers deeper, the current general population sperm count/concentration was lower than that of men of infertile couples from 1940-1943 cohort. Additionally, when the general population sperm count/concentration was lower than that of compared recent fertile men.

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.

I really don't understand the purpose of this study. Why give "healthy" men with normal lipids atorvastatin??? The study found a reduction in TC and LDL, but also a reduction in sperm number, decreased sperm vitality, increased sperm morphology, decreased prostatic acid pho sphatases, epididymal neutral alpha-glucosidase and L-carnitine levels resulted.

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.

Re-analysis of Carlsen's work on sperm count finds consistent decline in sperm count. Swan and authors found a 1.5% decline in US men from 1934-1996 and 3% annual decline in European/Australian men over same time frame. This was a meta-analysis of 101 studies from 1934-1996. Yes, there is geographical variation, but the overall trend is one of decline.

The embryo is the combined form of a matured egg and sperm. It is generally known as the most critical stage of IVF treatment. Despite that, successful embryo implantation only decides the achievement of pregnancy, and when it fails, it obstructs the entire IVF process. It extensively occurs when a couple fails to develop a healthy embryo using their eggs and sperm because of poor health conditions.
