Male Sexual Response: Erection & Ejaculation01:17

Male Sexual Response: Erection & Ejaculation

26.6K
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...

Penis

37.1K
The penis serves a dual role in sexual reproduction and urination. It consists of three main regions: the glans penis, the body, and the root, each with distinct functions and unique anatomical features.
Anatomy of the Penis
The glans penis, or the head, is the terminal part of the penis and houses the external urethral orifice, the exit point for urine and semen. Covered by the prepuce, or foreskin, the glans is noted for its sensitivity and plays a key role in sexual pleasure. The body of the...

Psychosexual Stages of Personality: Genital

2.1K
The genital stage is the final phase of Sigmund Freud's theory of psychosexual development, beginning at puberty, around age 12. During this stage, sexual energy shifts from self-focused interests to external individuals, marking the development of mature adult sexuality. Freud saw this phase as a time of sexual reawakening, with desires directed toward others outside the family. A healthy transition into this stage, according to Freud, signifies the emergence of two key aspects of adult...

Sperm Structure and Semen Composition01:22

Sperm Structure and Semen Composition

13.6K
During ejaculation, males release around 2-5 milliliters of semen, which is a complex mixture of mature sperm and various fluids produced by accessory glands. The mature sperm cells measure approximately 60 micrometers in length and consist of a head, neck, midpiece, and tail. The head is flattened and tapered, measuring about 4 to 5 micrometers in length. It contains a nucleus with condensed chromosomes and an acrosome, a cap-like structure filled with enzymes essential for penetrating the...

External Female Genitals

45.8K
The vulva encompasses the external structures of the female reproductive system. At the forefront is the monpubis, a cushion of fatty tissue atop the pubic bone. Once puberty sets in, this area typically grows hair. Extending from just behind the mons pubis are the labia majora (labia = 'lips'; majora = 'larger'), which are larger skin fs olds coated with hair. Nestled within are the labia minora (labia = 'lips'; minora = 'smaller'), which are thinner, more...

Accessory Glands of the Male Reproductive System01:16

Accessory Glands of the Male Reproductive System

4.4K
The accessory ducts involved in sperm maturation and transportation include the epididymides, vasa deferentia, ejaculatory ducts, and urethra. These ducts play a critical role in the maturation, storage, and transportation of sperm from the testes to the urethra, where it is then released during ejaculation.
The epididymis is a small, comma-shaped organ located at the back of each testicle. The epididymis can be divided into three main parts: the head, body, and tail. The head of the epididymis...

Anatomic variation and orgasm: Could variations in anatomy explain differences in orgasmic success?

Summary

Anatomical and neuro-anatomic variations significantly influence orgasm frequency and intensity, beyond commonly discussed factors like psychology or penis size. Understanding these differences can guide treatments to enhance sexual satisfaction.

Area of Science:

  • Anatomy
  • Neuroanatomy
  • Sexual Medicine

Background:

  • Public focus on sexual satisfaction often centers on psychological factors, penis size, and the G-spot.
  • Anatomical and neuro-anatomic variations may play a more significant role in orgasm frequency and intensity.

Purpose of the Study:

  • To review existing literature on anatomical sexual variations.
  • To explain how these variations may influence individual sexual experiences and satisfaction.

Main Methods:

  • Literature review using PubMed and OVID Medline.
  • Search terms included: orgasm, penile size variation, clitoral variation, Grafenberg spot, and benefits of orgasm.
  • Exploration of basic reproductive organ anatomy and innervation.

Main Results:

  • Male orgasm relies on the interplay of parasympathetic and sympathetic nervous systems.
  • Female orgasm is complex, with the clitoris and its anterior vaginal wall migration being primary.
  • Anatomical variations, beyond popular notions, likely play a superior role in sexual response.

Conclusions:

  • Orgasm is a complex interplay of psychological, physiological, and anatomical factors.
  • Individual anatomical variations predispose individuals to specific sexual functions.
  • Future research should investigate medical or surgical interventions to modify these variations for improved sexual function.
