The condition is most common in sports that emphasize leanness,  such as cross country running, gymnastics, and figure skating. Many of those who suffer from the triad are involved in some sort of athletics, in order to promote weight loss and leanness. The competitive sports that promote this physical leanness may result in disordered eating and be responsible for the origin of the female athlete triad. For some women, the disorder can have major health consequences. In addition, for some competitive female athletes, problems such as low self-esteem, a tendency toward perfectionism, and family stress place them at risk for disordered eating. Signs and symptoms
Clinical symptoms of RED-S may include disordered eating, fatigue, hair loss, cold hands and feet, dry skin, noticeable weight loss, increased healing time from injuries (e.g., lingering bruises), increased incidence of bone fracture and cessation of menses. Affected athletes may also struggle with low self-esteem and depression. Upon physical examination, a physician may also note the following symptoms: elevated carotene in the blood, anemia, orthostatic hypotension, electrolyte irregularities, hypoestrogenism, vaginal atrophy, and bradycardia.An athlete may show signs of restrictive eating, but not meet the clinical criteria for an eating disorder. They may also display subtle menstrual disturbances, such as a change in menstrual cycle length, anovulation, or luteal phase defects, but not yet have developed complete amenorrhea. Likewise, an athletes bone density may decrease, but may not yet have dropped below her age-matched normal range.
Other studies report PE prevalence ranging from 3 percent to 41 percent of men over 18, but the great majority estimate a prevalence of 20 to 30 percent—making PE a very common sex problem.There is a common misconception that younger men are more likely to develop premature ejaculation and that its frequency decreases with age. Prevalence studies have indicated, however, that rates of PE are constant across age groups. History
Male mammals ejaculate quickly during intercourse, prompting some biologists to speculate that rapid ejaculation had evolved into mens genetic makeup to increase their chances of passing their genes.Ejaculatory control issues have been documented for more than 1,500 years. The Kamasutra, the 4th century BCE Indian marriage handbook, declares: "Women love the man whose sexual energy lasts a long time, but they resent a man whose energy ends quickly because he stops before they reach a climax." Waldinger summarizes professional perspectives from early in the twentieth century.Sex researcher Alfred Kinsey did not consider rapid ejaculation a problem, but viewed it as a sign of "masculine vigor" that could not always be cured. The belief that it should be considered a disease rather than a normal variation, has also been disputed by some modern researchers. Psychoanalysis
Freudian theory postulated that rapid ejaculation was a symptom of underlying neurosis. It stated that the man has unconscious hostility toward women, so he ejaculates rapidly, which satisfies him but frustrates his lover, who is unlikely to experience orgasm that quickly. Freudians claimed that premature ejaculation could be cured using psychoanalysis.
