For the first four or five days, her uterus sloughs off part of its lining (endometrium). This accomplished, her complex hormonal system sends a messenger chemical to her ovaries, telling them to ripen one of the 50,000 or more potential egg cells with which she was born. Usually, only one ovary responds...

...conservative Italian members of the Pope's blue ribbon panel of experts, represents a new direction in official Catholic thinking on marriage problems. For that reason, a dissenting minority has objected strongly and urged that the only concession be approval of the pill to help regularize the female menstrual cycle, thus making more reliable the rhythm method of birth control.
