He points to a growing body of literature suggesting that fathers can pass on acquired traits. A study in December in the journal Nature Neuroscience, for instance, found that male mice conditioned by electric shocks to fear an arbitrary odor had offspring with the same phobia. A similar study discovered that baby mice born to stressed-out fathers displayed heightened anxiety and depression. Yet another experiment revealed that feeding male mice a high-fat diet before mating set off diabetes-like symptoms in their daughters.

This small protein hormone, a so-called RFamide-related peptide (RFRP), puts the brakes on reproduction by directly inhibiting GnRH.

Quantitative evaluation of spermatozoa ultrastructure after acupuncture treatment for idiopathic male infertility

Statistical evaluation of the TEM data showed a statistically significant increase after acupuncture in the percentage and number of sperm without ultrastructural defects in the total ejaculates. A statistically significant improvement was detected in acrosome position and shape, nuclear shape, axonemal pattern and shape, and accessory fibers of sperm organelles. However, specific sperm pathologies in the form of apoptosis, immaturity, and necrosis showed no statistically significant changes between the control and treatment groups before and after treatment.
