...study is the second to find some sort of difference between the hypothalami of gay and straight men. Last year a Dutch research team discovered that another group of neurons in this tiny gland is larger in homosexual than in straight men. But some scientists believe this structure governs daily rhythms rather than sexual behavior, so it is difficult to see any significance in the finding. Investigations of right- and left-handedness have also provided evidence of a physiological distinction. Sandra Witelson, a professor of psychiatry at McMaster University in Hamilton, Ont., has found more left-handers among homosexual women...
More than any other malignancy, cancer of the prostate has a reputation for stealth. While 122,000 American men were diagnosed with the disease last year -- making it the leading cancer among men -- 70% of those tumors had already managed to spread beyond the gland and into the rest of the body without being detected. Frustrated surgeons have long hoped for a test that could pick up more of these cancers before they become inoperable. Now they may have got their wish. Researchers reported in last week's New England Journal of Medicine that a new method could potentially spot...
Rectal examinations have been the standard for early diagnosis for nearly a century. But this method, in which doctors probe the prostate gland manually, has not been very popular with patients or their doctors. In West Germany, where men over 40 can be tested for free, a recent study found that only 15% actually agreed to have it done. Physicians point out that the exams often fail to detect smaller cancers and those that originate on the front of the gland. The method is also subjective. One expert remarked that all he can tell his medical students is that...
...years it was thought that these changes were inexorable and irreversible, but it is now clear that they are influenced by changing levels of HGH. Produced by the pituitary gland at the base of the brain, the hormone stimulates the growth of bones and organs in children and helps maintain healthy tissues in older people...
...like going to the dentist, only better," said Barbara Bush last week, after undergoing the first of ten consecutive days of radiation therapy at Washington's Walter Reed Army Medical Center. She is being treated for Graves' disease, an affliction that inflames the thyroid gland and can cause bulging, watery eyes and double vision. After her session, she dashed off with characteristic aplomb to the White House pool for her customary 60 laps...
