Research overview: vaginocervical stimulation and the ovulatory reflex

The ovulatory reflex in cats is triggered when sensory receptors in the vagina and cervix are stimulated during intromission, sending signals through the spinal cord and hypothalamus to the pituitary. This overview surveys experimental work using mechanical stimulation to mimic mating and trigger ovulation, demonstrating that the genital stimulus itself, rather than other aspects of copulation, drives the hormonal response. It considers how the intensity and repetition of stimulation modulate the strength of the luteinizing hormone surge. These findings illuminate the neuroendocrine pathway underlying reflex ovulation and have informed methods for inducing ovulation noninvasively. The topic connects basic neurophysiology to practical reproductive management and to comparative studies of induced ovulation across mammals.
