Fertilization of Human Eggs in Vitro: A Defense
The widespread debates arising from medical advances have become a familiar aspect of contemporary society, and the clinical application of man's increasing control over his physiological and biochemical systems is bound to stimulate further controversy. This review is concerned with the current debate on one of these novel advances-the fertilization of human oocytes in vitro, and their reimpla...
متن کاملEffects of Hypothermia and Hyperthermia on Fertilization in Rat Eggs
INTRODUCTION The effects of heat and cold upon the course of fertilization in rats have been studied by immersing the Fallopian tube in water at 44-5-45-5° C, and by applying ice to the tube, both procedures being employed after ovulation (Austin & Braden, 19546). The chief effects of the hot-shock treatment were a temporary inhibition of the second maturation division and a large increase in t...
متن کاملIn vitro fertilization and artificial activation of eggs of the direct-developing anuran Eleutherodactylus coqui
Although much is known about the reproductive biology of pond-breeding frogs, there is comparatively little information about terrestrial-breeding anurans, a highly successful and diverse group. This study investigates the activation and in vitro fertilization of eggs of the Puerto Rican coqui frog obtained by hormonally induced ovulation. We report that spontaneous activation occurs in 34% of ...
متن کاملRisk of multiple birth associated with in vitro fertilization using donor eggs.
Multiple birth, which is associated with adverse fetal, infant, and maternal outcomes, is increasingly related to the use of in vitro fertilization (IVF). Among women undergoing IVF who use their own eggs, greater maternal age is associated with decreased risk of multiple birth; using donor eggs from younger women may negate this age effect. Data from 6,936 IVF procedures performed in the Unite...
