...Greatest problem of old age: resignation. Contrary to popular belief, old people are far from sexless. The flow of sex hormones does not ebb when men reach their 60s and 70s. Says Columbia's Anatomist Earl Theron Engle, spermatozoa are formed in at least 50% of old men. Bending a Freudian ear to their querulous complaints, Psychiatrist Gilbert Van Tassel Hamilton of Santa Barbara, Calif, offers the opinion that old men & women are no less troubled by sex problems than are the young. Says he: "Many persons . . . who have passed their sixtieth year vaguely feel that it is time...
...fertility during his twenties, Dr. Pelzman's present list of 15 is drawn mostly from medical students and interns who are glad to get the $25 fee per insemination. Operation of the bureau will be very simple. Dr. Pelzman will merely collect to order tubes of fresh, fertile spermatozoa and deliver them to a gynecologist...
...laboratory Dr. Perry induced unseasonable sex activity by shining ordinary 25-watt lamps on sparrows much less than a year old. The beaks of the males turned dark and their testes developed spermatozoa; the ovaries of the females were swollen, contained numerous eggs. The scientist evoked even more pronounced gland changes with ultraviolet light...
...great discoveries of modern genetics is that certain hereditary characters are linked to the sex factor. Males manufacture two kinds of spermatozoa, one bearing a y-chromosome, the other an x-chromosome. If a y-chromosome spermatozoon happens to penetrate the female ovum, the get is a boy; if an x-chromosome, it is a girl. Thus Professor Crew reasoned the shorter life expectancy of the male seems to be carried on a gene or genes in the y-chromosome. By delicate manipulations, geneticists have had some success in separating male and female elements in mammalian sperm, opening the prospect...
...contraceptive is a synthetic, hormone-like substance to be administered hypodermically. It inhibits the production of ova, without which no woman can conceive. In this respect it differs from spermatoxin, an extract of spermatozoa, which renders a woman transiently infertile when injected into her arm like a vaccine. As long as her blood is stimulated by spermatoxin no spermatozoa can affect her and she cannot have babies. Not all women will endure injections of spermatoxin, because it may render them allergic and put them in a class with victims of hives...
