Physiology: the Mystery of regulating female sexual function

Uncover the secret! The neurological basis of female sexual function is not very clear, but it is believed that female sexual function is regulated by the tertiary nerve center. The primary center penis pumping , the primary center of sexual function, is located in the lower segment of the spinal cord, also known as the spinal cord center, which participates in the regulation of sexual excitement and sexual behavior through the external and internal sexual organs innervated by the trunk and sympathetic and parasympathetic nerves. The secondary center is located in the subcortical center of the hypothalamus and hindbrain, which regulates sexual function mainly by secreting gonadotropin-releasing hormone. The tertiary center, which is located in the limbic system of the cerebral cortex, especially in the septal area and related structures, is the highest center for the regulation of sexual function. Through the regulation of the hypothalamic-pituitary-egg axis, the reproductive organs change periodically and affect the sexual function. Gonadotropin-releasing hormone secreted by the hypothalamus acts on the anterior pituitary to synthesize and release follicle-stimulating hormone and luteinizing hormone (luteinizing hormone). With the participation of a small amount of luteinizing hormone, follicle-stimulating hormone makes the follicles in the ovary mature and secrete estrogen. Under the action of estrogen, the endometrium changes in the proliferative phase. The secretion of estrogen reaches the highest peak before ovulation and produces positive and negative feedback to the hypothalamus-pituitary gland. Positive feedback is to promote the release of luteinizing hormone from the pituitary gland, while negative feedback is to inhibit the release of follicle-stimulating hormone.

What are the short-term contraceptive methods for women to protect themselves during sex? After passion, how to implement effective contraception? Uncover the secret! The mystery of the regulation of female sexual function when the release of luteinizing hormone reaches its peak, it triggers ovarian ovulation with the participation of follicle-stimulating hormone and causes ruptured follicles to form corpus luteum. The luteum secretes progesterone and estrogen, and the endometrium becomes secretory due to the action of progesterone. With the increase of progesterone and estrogen secretion reached the peak, it inhibited the hypothalamus-pituitary gland (negative feedback), resulting in the decrease of follicle-stimulating hormone and luteinizing hormone released by pituitary. As a result, corpus luteum atrophy, progesterone and estrogen secretion decreases penis sucking , so the endometrium is difficult to maintain and fall off to form menstruation. Due to the decrease of progesterone and estrogen, the inhibition of hypothalamus-pituitary is lifted bdsm chastity , and the pituitary releases follicle-stimulating hormone again, the new follicle begins to develop again, and the new cycle begins again. Recent studies have shown that the release of gonadotropin-releasing hormone by some neurons in the hypothalamus is controlled by monoamine neurotransmitters released by some neurons in the brain, such as dopamine. and those neurons that release monoamine neurotransmitters are affected by more advanced nerve centers, such as mental activity of the brain. In addition, the pituitary gland also secretes prolactin, which cooperates with estrogen and progesterone and promotes the development and secretion of the breast, which is controlled by the hypothalamus; the ovary also secretes a small amount of androgen, which can be converted into estrogen and play the role of estrogen. And can cause clitoral enlargement and so on. From the endocrine point of view, estrogen has a greater impact on female libido, followed by androgen.
