Rape Results In More Pregnancies Than Consensual Sex, Not Fewer

Excerpt:  There’s no direct evidence yet of sex-induced ovulation in humans, although there’s some very new research hinting at the possibility. The LH in semen has been shown to trigger ovulation in camels, alpacas and llamas.

In every other species of reflex ovulator its the effect of pheromones on LH that triggers ovulation. This brings up the question of what common neurophysiological mechanism evolved (e.g., in some but not other mammals) to allow semen to trigger ovulation in the absence of the pheromones. What evidence suggests that semen alone is the trigger?  It also brings up the question about familiarity with existing evidence of sex-induced ovulation in humans. Is this the 1973 study that’s mentioned in the article?

Jochle, W. (1973) Coitus induced ovulation. Contraception, 7, 523-564.

The effect on LH could be expected to come from the influence of pheromones on gonadotropin releasing hormone (GnRH) neurosecretory neurons. The olfactory/pheromonal stimulus doesn’t change when force is used and neither does its epigenetic effects on intracellular signaling and stochastic gene expression that result in the GnRH-directed response common in mammals due to conservation of the GnRH molecule in vertebrates across 400 million years of Creation (e.g., via evolution).

I think this may indicate how many people can be offended by the basic principles of biology and levels of biological organization required to link sensory stimuli to genetically predisposed effects on hormones and their affects on behavior. For example, there are similar effects reported in mammals that are linked directly to the pheromones of the female and testosterone increase in males:   “The functional significance of the conditioned change in LH secretion lies principally in the unequivocal demonstration that environmental cues can activate the pituitary-testis axis in a way that mimics, in every respect, the activation achieved by exposure to a female.

But wait, what if the epigenetic effects of pheromones on hormones associated with the physical trauma caused PTSD in women that affected subsequent behavior? Would that not exemplify taking the understanding of socioaffective neuroscience too far? If so, there’s no immediate danger I may be the only researcher who is capable of understanding the socioaffective nature of evolved behaviors, and detailing how “Olfaction and odor receptors provide a clear evolutionary trail that can be followed from unicellular organisms to insects to humans.” — as I did in Kohl, J.V. (2012) Human pheromones and food odors: epigenetic influences on the socioaffective nature of evolved behaviors. Socioaffective Neuroscience & Psychology, 2: 17338.

About James V. Kohl 1308 Articles
James Vaughn Kohl was the first to accurately conceptualize human pheromones, and began presenting his findings to the scientific community in 1992. He continues to present to, and publish for, diverse scientific and lay audiences, while constantly monitoring the scientific presses for new information that is relevant to the development of his initial and ongoing conceptualization of human pheromones. Recently, Kohl integrated scientific evidence that pinpoints the evolved neurophysiological mechanism that links olfactory/pheromonal input to genes in hormone-secreting cells of tissue in a specific area of the brain that is primarily involved in the sensory integration of olfactory and visual input, and in the development of human sexual preferences. His award-winning 2007 article/book chapter on multisensory integration: The Mind’s Eyes: Human pheromones, neuroscience, and male sexual preferences followed an award winning 2001 publication: Human pheromones: integrating neuroendocrinology and ethology, which was coauthored by disinguished researchers from Vienna. Rarely do researchers win awards in multiple disciplines, but Kohl’s 2001 award was for neuroscience, and his 2007 “Reiss Theory” award was for social science. Kohl has worked as a medical laboratory scientist since 1974, and he has devoted more than twenty-five years to researching the relationship between the sense of smell and the development of human sexual preferences. Unlike many researchers who work with non-human subjects, medical laboratory scientists use the latest technology from many scientific disciplines to perform a variety of specialized diagnostic medical testing on people.
