THE EMOTIONAL RESPONSES OF MARRIED WOMEN RECEIVING ORAL CONTRACEPTIVES.

One hundred women taking oral contraceptives were questioned concerning their opinions about personal and sociological effects of this method of conception control. Fifty-three per cent reported improved coital satisfaction while 4% noted the opposite effect. Libido was increased in 22% and decreased in 13%. One woman in five believed that an increase in premarital and extramarital sexual activity would take place in the general population as a result of tablet-induced infertility. The problem of population control is discussed. It is paradoxical that the incidence of unplanned pregnancies continues to increase despite the availability of completely reliable conception control. This reflects present inability to communicate contraceptive knowledge to the appropriate people.

THE CONTROVERSIAL AND DYNAMIC OVARY.

The ovaries from 75 females ranging in age from the newborn to 96 years were subjected to histologic scrutiny. Ageing phenomena comprising the gonad's life-long metamorphosis were documented. The cause of menopausal ovarian failure is twofold: (1) Ovarian vessel wall thickening and hyalinization as the cardiovascular system ages reduces perfusion of the gonad. (The blood supply of the ovaries is well designed to permit mobility but longevity of function is sacrificed.) (2) Gradual replacement of egg- and hormone-producing cells by fibrous tissue. This scar tissue accumulates as a result of ovulation and pregnancy and is less efficiently removed from the ovary in the later fertile years. By inhibiting ovulation, the oral contraceptives will likely delay the natural senescence of the ovary. More basic research is indicated to elucidate the mechanism of oogenesis.

Current concepts in conception control.

The progressive increase in world population has become a most urgent global problem in recent years. Man has, however, been interested in controlling his reproductivity at the family level for many centuries. Historical aspects of this saga are reviewed.The modern era of conception control was ushered in by Makepeace et al. in 1937 when ovulation inhibition by progesterone was demonstrated. Confirmation of this by Pincus and associates, and development of the potent oral progestational agents, the 19-norsteroids, have made efficient reliable contraception a reality.Experience with one of these agents (Ortho-Novum, 2 mg.) in 115 patients through 805 cycles is presented. Conception control was 100% effective at this dosage. Side effects were minimal. Only three of the women discontinued the tablets because of these effects. All but five in this group of 115 preferred the oral contraceptives to methods previously employed.
