(X-philes will recall that, in the shank of the series, Scully bore a child, William, through in vitro fertilization; the sperm may have been Mulder's. The boy in the hospital would be about...
While I was reading the report on Margie Profet's ''radical theory,'' which proposes that menstruation protects against sperm-borne infection ((HEALTH, . Oct. 4)), an obvious hole came to mind. Human females may engage in sexual intercourse, and thereby expose themselves to potentially harmful micro- organisms, at any time during their menstrual cycle. If a woman were to have sex the day after her menstrual period ended, it would be another three weeks before her uterine lining was again sloughed off, which is more than enough time for an infection to set in. Because of this constant risk of exposure...

...some researchers worry that BPA and phthalates could do the same, especially in young children. Animal studies on BPA found that low-dose exposure, particularly during pregnancy, may be associated with a variety of ills, including cancer and reproductive problems. Some human studies on phthalates linked exposure to declining sperm quality in adult males, while other work has found that early puberty in girls may be associated with the chemicals...
...commonly used argument against compensated kidney donation is that people in poverty would be most likely to sell their organs. While perhaps true, this concern neglects the fact that we already allow people with low-incomes to make their own decisions regarding the sale of their sperm, eggs and blood. Both kidney and egg donation are invasive procedures that come with associated risks. The decision whether or not to sell an organ would also not be made in a vacuum and one would expect medical professionals to fully present the associated (albeit minor) risks of kidney donation before surgery...
