Eat poorly, and your body will remember—and possibly pass the consequences onto your kids. Today, in two complementary studies, scientists tell us how. As sperm traverse the male reproductive system, they jettison and acquire non-genetic cargo that fundamentally alters sperm before ejaculation. Each year, over 76, children are born as a result of assisted reproduction techniques, the majority of which involve some type of in vitro fertilization IVF. Multiple variations on IVF exist, but in some cases that involve male infertility—for instance, sperm that struggle to swim—sperm must be surgically extracted from the testes or epididymis, a lengthy, convoluted duct that cradles each testis. After sperm are produced in the testes, they embark on a harrowing journey through the winding epididymis—which, in a human male, is about six meters long when unfurled—on their way to storage.

Surprisingly, the study, which analysed data on the sperm counts of 42, men, found no decline in sperm counts in men from Asia, Africa and South America, although there was limited data from these areas. Overall, this is a very disturbing report. There has been a longstanding debate among scientists as to whether sperm counts have decreased or not. But what's different about this study is the quality of the analysis.
