The testicles (or testes) are two small organs that are responsible for making sperm and helping to make the main male sex hormone testosterone. They are held in a bag of skin known as the scrotum behind the penis.
Female sexual arousal disorders affect an individual’s mental or genital arousal response. Sometimes, a woman with a sexual arousal disorder may feel mentally turned on, but her body and genitals cannot respond to sexual stimulation.
Persistent genital arousal disorder/genito-pelvic dysesthesia (PGAD/GPD), originally described as persistent sexual arousal syndrome (PSAS), is a disorder that causes people to have unwanted or disruptive feelings of genital arousal
Peyronie’s Disease is a condition resulting from scar tissue formation on the penis. The scar, which is often referred to as a “plaque,” develops on the sheath surrounding the vascular erectile tissue within the penile shaft. This may result in changes to the shape of the penis such as bending/curvature, narrowing, and penile shortening.
If you’re a man past middle age, there’s a good chance that you have or may develop a condition known as benign prostatic hyperplasia (BPH). This noncancerous condition affects about 40% of men in their 50s, 60% of men in their 60s, and more than 80% of men in their 80s.
Hypoactive sexual desire disorder (HSDD) refers to person’s chronic or ongoing lack of interest in sex, to the point of personal or relationship distress. HSDD affects both men and women, however it is most common in women.
What is erectile dysfunction (ED)?
Erectile dysfunction (ED) occurs when a consistent inability to get or maintain an erection prevents you from having satisfying sex. A man with ED either loses his erection before intercourse, gets only a partial erection, or gets no erection at all. ED is sometimes called impotence, but the preferred term is ED.
Anejaculation is defined as the inability to ejaculate semen; the word itself means “no ejaculation.” With this condition, a man can produce sperm but cannot expel them during normal ejaculation even though he may have normal orgasm sensation. Anorgasmia refers to the lack of orgasm (or sensation of pleasure). Anorgasmia can occur without ejaculation, or occasionally with normal ejaculation. Normal ejaculation without pleasure/orgasm is called “orgasmic anhedonia.”
Delayed orgasm and delayed ejaculation (also historically referred to as retarded ejaculation) refer to difficulty reaching orgasm (climax) and/or ejaculating even with a firm erection and sufficient sexual arousal and stimulation. This delay is often associated with personal distress. Delayed orgasm or ejaculation is estimated to occur in 1-4% of men.
Testosterone is a hormone made mostly by the testicles in men. It plays an important role in making new red blood cells, increasing muscle mass and strength, enhancing sex drive, maintaining sperm production, and improving bone density.
Sexual stimulation (physical) causes nerves in the penis to send chemical messages to the spinal cord and the brain. Similarly, the brain releases chemicals with mental stimulation. These chemicals help relay messages of stimulation throughout the brain, while nerve signals from the brain carry these messages to the rest of the body through the spinal cord to the male reproductive organs. When a man reaches a certain level of excitement during this process, chemical and nerve messages sent to the pelvis cause ejaculation. While not completely understood, it is believed that the chemical serotonin plays a major role in this process.
The prostate is a small, walnut-sized, gland located below your bladder that surrounds your urethra. It produces some of the fluid that makes up semen, the fluid that comes out at the time of ejaculation. As men age the prostate grows and can cause obstruction or blockage of the urine stream; this is referred to as benign prostatic hyperplasia, or BPH.
