No-scalpel Vasectomy
Vasectomy is a simple and effective method for providing permanent contraception. Vasectomy is the surgical interruption of the two tubes (vas deferens) that carry a man's sperm from his testicles to his ejaculatory ducts, where the sperm are stored before departure from his body during orgasm. A vasectomy prevents sperm from being added to the man's ejaculation fluid (semen); therefore, he can no longer make a woman pregnant.
Ejaculatory Dysfunction
Emission is accomplished by contraction of the vas deferens, seminal vesicles, and ejaculatory ducts. This process is under adrenaline control. Ejection results from the rhythmic contractions of the muscles around the urethra, which causes the forcible ejection of the ejaculate. Within the spinal cord lies the ejaculation center which is the area involved in the coordination of signals from the brain and penis that eventually lead to ejaculation.
In normal men there exists a linear sexual response cycle: desire, arousal, plateau, orgasm, and resolution.
Penile Fracture
Abrupt bending of the erect penis can result in a tear in the tunica albuginea (the lining of the erectile bodies). This results in the instantaneous loss of the erection. In extreme cases, a tear in the urethra (urine channel) can also occur.
Priapism
The duration of the erection considered to represent priapism is generally over four hours.
Erectile Dysfunction
What is Erectile Dysfunction?
Erectile dysfunction (ED) can be classified as organic, psychogenic or mixed. Organic ED is due to physical defects and can be further sub-classified. Psychogenic ED is secondary to psychological factors that are thought to inhibit a man's ability to achieve an erection because of specific stressors. ED often has a mixed component of both organic and psychogenic etiologies.
Peyronie's Disease
Peyronie's disease is a medical condition characterized by the development of a lump on the shaft of the penis. This lump is a scar (plaque) that forms on the lining (tunica albuginea) of the penile erectile body (corpus cavernosum). It is believed to be the result of direct injury to the penis. Early on following the trauma, an inflammatory reaction occurs, often bringing a man's attention to the problem because of pain associated with his erection. With time, the inflammation progresses and a scar develops.
