32. See, for example, Roney et al. (2003). Regular aerobic exercise, lots of garlic, stress avoidance, and plenty of sleep are also good ways to “keep it up.” We should note that despite the anecdotal evidence, few scientists have risked ridicule by applying for grants to study the hormonal changes in philanderers. The phenomenon is well documented in other mammals, however (see, for example, Macrides et al., 1975). It’s possible the effect may be mediated not by actual intercourse so much as by pheromones, which might explain the bulusela shops where Japanese men purchase girls’ vaccum-packed (but used) panties from vending machines. Enterprising graduate students might want to consider research similar to Wedekind’s “Sweaty T-shirt study,” but with women’s panties instead of men’s shirts in the plastic bags, to see whether exposure to novel women’s genital pheromones alone is enough to affect testosterone blood concentrations in men.
