Human Ovulation and Menstruation

The Association between Endometriomas and Ovarian Cancer: Preventive Effect of Inhibiting Ovulation and Menstruation during Reproductive Life

Although endometriosis frequently involves multiple sites in the pelvis, malignancies associated with this disease are mostly confined to the ovaries, evolving from an endometrioma. Endometriomas present a 2-3-fold increased risk of transformation in clear-cell, endometrioid, and possibly low-grade serous ovarian cancers, but not in mucinous ovarian cancers. These last cancers are, in some aspe...

Woman, moon and menstruation.

“The pituitary has an intrinsic rhythm of small amplitude with a frequency of every two to ten minutes. Superimposed on this intrinsic rhythm is a rhythm caused by the pulsatile release of hypophysiotropic releasing factors, with or without the withdrawal of a corresponding inhibitory factor. Rhythms that are shorter than a day are referred to as ultradian rhythms. The next layer of rhythmicity...

Bio-Electric Correlates of Human Ovulation *

In a series of studies recently reviewed by Northrop and Burr' it has been shown that living organisms possess electrical properties which can be measured with considerable accuracy. These potential gradients are not chaotic but seem to be organized in characteristic patterns which are peculiar to the species, the strain and, quite possibly, the individual.5 The general occurrence of these bio-...

Vocal cues of ovulation in human females.

Recent research has documented a variety of ovulatory cues in humans, and in many nonhuman species, the vocal channel provides cues of reproductive state. We collected two sets of vocal samples from 69 normally ovulating women: one set during the follicular (high-fertility) phase of the cycle and one set during the luteal (low-fertility) phase, with ovulation confirmed by luteinizing hormone te...
