Male Sexual Response: Erection & Ejaculation01:17

Male Sexual Response: Erection & Ejaculation

1.2K
Sexual stimulation can take various forms, such as physical touch and visual or auditory cues. When this happens, the parasympathetic reflex in the sacral portion of the spinal cord is activated. This reflex stimulates the release of nitric oxide (NO), which then dilates the arterioles in the penis, increasing blood flow to the erectile tissues - the corpora cavernosa and corpus spongiosum.
The blood filling the erectile tissues compresses the veins, which helps to prevent blood from leaving...

Endocrine Signaling01:45

Endocrine Signaling

63.8K
Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the circulatory system. This exposes the whole organism to the hormone but only those cells expressing hormone receptors or target cells are affected. Thus, endocrine signaling induces slow responses from its target cells but these effects also last longer.

Gonadal and Placental Hormones01:24

Gonadal and Placental Hormones

1.2K
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...

Spermatogenesis01:41

Spermatogenesis

101.8K
Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male...

Local Anesthetics: Clinical Application as Epidural Anesthesia

400
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Birth Control Methods01:22

Birth Control Methods

137
Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Summary
This summary is machine-generated.

Female sexual activity may prepare women for childbirth, a concept termed "practice for parturition." This framework suggests sexual function and birth outcomes are linked, with potential benefits for labor and delivery.

Area of Science:

  • Reproductive Biology
  • Human Sexuality
  • Obstetrics

Background:

  • Reproductive biologist Niles Newton noted similarities between female sexual response and childbirth.
  • Phenotypic overlap suggests shared mechanisms, with potential for dysfunction in one affecting the other.
  • Limited research exists on pre-birth female sexuality's impact on parturition.

Purpose of the Study:

  • To introduce and describe the "practice for parturition" framework.
  • To propose that sexual activity prepares women physically and psychologically for childbirth.
  • To investigate the interrelationship between female sexuality and birth outcomes.

Main Methods:

  • Detailed review of female genito-pelvic reflexes and psychological states.
  • Three systematic reviews evaluating hypotheses on pelvic floor interventions, pre-birth sexual activity, and sexual dysfunction.
  • Analysis of existing literature on sex-birth interrelationships.

Main Results:

  • Evidence supports that pelvic floor interventions improve sexual function and birth outcomes.
  • Pre-birth sexual activity/function appears to predict improved labor and birth.
  • Sexual dysfunction may impair birth outcomes, though direct links to orgasm/arousal are sparse.

Conclusions:

  • The "practice for parturition" framework offers a testable model for understanding benefits of female sexuality on birth.
  • Sexual activity may serve as a natural preparation for childbirth.
  • Further research is needed to explore specific mechanisms linking female orgasm/arousal to parturition.
