Masturbation, a brief description

Masturbation is the sexual stimulation of the genitals, usually to the point of orgasm. The stimulation can be performed using the hands, fingers, everyday objects, or dedicated sex toys. Mutual masturbation, masturbation with a partner, can be an alternative to sexual intercourse.

Studies have found that masturbation is frequent in humans of both sexes and all ages, although there is variation. Various medical and psychological benefits have been attributed to a healthy attitude to sex in general and to masturbation in particular, and no causal relationship is known between masturbation and any form of mental or physical disorder. Acts of masturbation have been depicted in art worldwide since prehistory. While there was a period (from the late 18th to the early 20th century) when it was subject to medical censure and social conservatism, it is considered a normal part of healthy life today.
Different studies have found that masturbation is frequent in humans. Alfred Kinsey's 1950s studies on US population have shown that 92% of men and 62% of women have masturbated during their lifespan. Similar results have been found in a 2007 British national probability survey. It was found that, between individuals aged 16 to 44, 95% of men and 71% of women masturbated at some point in their lives. 73% of men and 37% of women reported masturbating in the four weeks before their interview, while 53% of men and 18% of women reported masturbating in the previous seven days.

In 2009, the UK Government joined the Netherlands and other European nations in encouraging teens to masturbate at least daily. An orgasm was defined as a right in its health pamphlet. This was done in response to data and experience from the other EU member states to reduce teen pregnancy and STIs (STDs), and to promote healthy habits.
Female masturbation alters conditions in the vagina, cervix and uterus, in ways that can alter the chances of conception from intercourse, depending on the timing of the masturbation. A woman's orgasm between one minute before and up to 45 minutes after insemination favors the chances of that sperm reaching her egg. If, for example, she has had intercourse with more than one male, such an orgasm can increase the likelihood of a pregnancy by one of them. Female masturbation can also provide protection against cervical infections by increasing the acidity of the cervical mucus and by moving debris out of the cervix. In males, masturbation flushes out old sperm with low motility from the male's genital tract. The next ejaculate then contains more fresh sperm, which have higher chances of achieving conception during intercourse. If more than one male has intercourse with a female, the sperm with the highest motility will compete more effectively.

A 2003 Australian study found that men who ejaculated more than five times a week were a third less likely to develop prostate cancer. It also has the added advantage preventing erectile dysfunction and incontinence. Train yourself by timing how long it takes you to orgasm, suggests Ava Cadell, Ph.D., founder of loveologyuniversity.com. If it usually takes two minutes solo, try for three next time. Or count how many strokes you need to get to your happy place. If you’re spurting after 50, shoot for 60. “Most men can double the number of strokes and the time within one month,”

Ejaculation increases levels of the hormone cortisol, says Jennifer Landa, M.D., a specialist in hormone therapy. Cortisol, which usually gets a bad reputation as a havoc-wrecking stress hormone, actually helps regulate and maintain your immunity in the small doses. “Masturbation can product the right environment for a strengthened immune system,” she says.

Masturbating releases a slew of feel-good neurochemicals like dopamine and oxytocin that lift your spirits, boost your satisfaction, and activate the reward circuits in your brain. An orgasm is the biggest non-drug blast of dopamine available. A brain scan of someone having an orgasm looks similar to a heroin addicted brain.
As well as the beneficial effects from hormones released from masturbation there are positive medical factors in Sperm.
There are studies that have shown that semen could act as an antidepressant in women. The study included sexually active college females and found that not only were females who were having sex without condoms less depressed, but depressive symptoms and suicide attempts among females who used condoms were higher.

Semen contains at least 13 prostaglandins and high concentrations of hormones that retain potency if taken orally. The quality of the seminal hormones is thought to be superior to even prescription versions. In the study women who regularly consumed their lovers sperm showed such benefits as a reduction in ovarian cancers, lowered depression and many even had acne symptoms lessen or stop entirely. It is thought that the oral consumption of the potent hormones had a balancing effect on woman's hormonal ups and downs caused by their periods and pregnancy or breastfeeding. Semen is not only rich in vitamin "E" but it is a natural lubricant that moisturizes the skin and causes it to glow, which is good for the skin.
The key to the findings is "regular consumption". But only married or monogamous women showed the benefits. Those with multiple partners showed no beneficial effects or even reported detrimental effects. This is thought to be caused by the differences in the hormonal makeup of multiple partners.

While Female ejaculation comes from an area called the urethral sponge, or "female prostate." A watery fluid can be ejected from this gland upon orgasm (or sometimes without orgasm). This gland is analogous to the male prostate and thus its secretions are very similar to those of the male prostate.
Though it is not entirely clear what female ejaculate is made up of, researchers have concluded that it is not purely urine, and that it is not the odourless secretion of the Bartholin gland that helps lubricate the vaginal tract, but a combination of urine, acid phosphotase and other inconsistent chemicals.

These studies have also shown the existence of a prostate-like gland within females, previously thought to be non-existent. In 2007, the well-known Viennese researcher Dr Florian Wimpissinger published an important study on two women who habitually ejaculated. He and his colleagues found that the ejaculate from these two females was chemically very different from that of their urine. In particular, it contained more prostatic acid phosphatase (PAP), more prostate-specific antigen (PSA), and also some glucose.
The scientific reasoning of masturbation actually benefits human health can be argued but usually from a religious stand point. Although human sexuality is a personal preference, one can not ignore the positive effects that a simple body function can aid human health...
