Penis01:29

Penis

44.0K
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...

Male Sexual Response: Erection & Ejaculation

29.0K
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...

Accessory Glands of the Male Reproductive System

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...

Urethra01:16

Urethra

6.6K
The urethra is a hollowed tubular organ through which urine is expelled from the body. This structure extends from the bladder to the external opening, allowing urine to be released.
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male...

Accessory Ducts of the Male Reproductive System

4.5K
The male reproductive system is a complex network of organs and tissues that work together to produce and transport sperm. The epididymis, vasa deferens, ejaculatory ducts, and urethra are the accessory ducts involved in sperm maturation and transportation. These ducts play a critical role in the production and transportation of sperm from the testes to the urethra, where it is then released during ejaculation.

External Female Genitals01:15

External Female Genitals

51.6K
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...

    Summary

    Penile frenulum lengthening significantly increases intravaginal ejaculation latency time (IELT) in men with premature ejaculation (PE). This surgical intervention leads to high patient satisfaction and improved sexual function.

    Area of Science:

    • Urology
    • Sexual Medicine
    • Surgical Innovation

    Background:

    • Premature ejaculation (PE) is a common sexual dysfunction.
    • A short penile frenulum is often associated with PE.
    • The role of the penile frenulum in sexual function is increasingly recognized.

    Purpose of the Study:

    • To assess the efficacy of penile frenulum lengthening in treating premature ejaculation (PE).
    • To evaluate the impact of frenulum modification on intravaginal ejaculation latency time (IELT).

    Main Methods:

    • A study included 34 males diagnosed with PE.
    • Participants with short frenulum underwent frenulum lengthening, with some receiving reconstruction post-circumcision.
    • Surgical procedures were performed on individuals with or without prior circumcision and those with redundant prepuce.

    Main Results:

    • Significant increase in intravaginal ejaculation latency time (IELT) observed one month post-surgery.
    • IELT improved from a baseline average of 1.12-1.50 minutes to 4.75-7.00 minutes across different patient groups.
    • 94% of patients reported satisfaction with sexual intercourse after the procedure.

    Conclusions:

    • The penile frenulum is crucial for maintaining penile erection.
    • Reconstruction and lengthening of the penile frenulum effectively prolong erection and IELT in PE patients.
    • Surgical frenulum modification offers a viable treatment option for premature ejaculation.
