For most men, ejaculating is synonymous with having an orgasm, although some men can have an orgasm without ejaculating. Ejaculate contains fluid from the prostate, seminal vesicles, and bulbourethral glands. Though it contains a wide variety of substances , including citric acid, cholesterol , mucus, and water, its primary job is to deliver sperm. Research shows that the frequency with which a man ejaculates may affect his health, sperm count, and overall well-being. This article looks at how often a man should release sperm, whether there is a link between ejaculation and cancer , and the effects of ejaculation on the body. Many men may wonder whether their sexual behavior is normal.
Understanding Arousal and Orgasm Dysfunction
A person who has a penis may be able to come anywhere from one to five times in a single session. When semen is released from the testes and the epididymis and exits the end of the penis during ejaculation, the body immediately begins producing more. You may notice, however, that each subsequent ejaculation produces less semen.
Delayed ejaculation refers to a difficulty or inability of a man to reach an orgasm and to ejaculate semen. The causes can be physical or psychological. Delayed ejaculation affects around 1 to 4 percent of men. It can result in distress for both the man and his partner. It can trigger anxiety about general health, low libido, and sexual dissatisfaction. Relationship problems include a fear of rejection for both parties and concern for couples who wish to start a family. Most men will experience delayed ejaculation at some point in their lives, but for some, it is a lifelong problem. Delayed ejaculation can have a psychological or biological cause. There can also be overlap between the two. It can be a lifelong condition, where a man has always had difficulty reaching an orgasm, but more commonly, delayed ejaculation occurs after a period of normal function.
Although it seems simple enough, the male orgasm is actually a complex process. Men achieve orgasm through a series of steps involving a number of organs, hormones, blood vessels, and nerves working together. The typical result is ejaculation of fluid that may contain sperm through strong muscle contractions. The fuel for the process leading to orgasm is testosterone , a hormone produced in steady supply by the testicles. The testicles also make millions of sperm each day, which mature and then are mixed with whitish, protein-rich fluids. These fluids nourish and support the sperm so they can live after ejaculation for a limited time. This mixture of fluid and sperm, known as semen, is what is moved through the urethra and out the penis during orgasm. The testosterone flowing through a man's body, along with psychological factors, determines the strength of his desire for sex. Testosterone is the primary factor which drives sexual desire, says Michael Ingber, MD , a physician in urology and female pelvic medicine and reconstructive surgery at the Atlantic Health System in Morristown, New Jersey, and a fellow of the International Society for the Study of Women's Sexual Health.
