Well, it makes people feel good, and feeling good is a large part of being healthy. On a more pregnancy specific note (of interest to me at the moment), I've been told that having sex, particularly the orgasm part for both men and women is very good for the growing baby as it releases all kinds of happy hormones that make the baby feel good. Also, on another pregnancy note, there are chemicals in semen which can help you go into labour, so it's pretty good if you're overdue!

Absolutely NOT. The orgasm, yes, but the ejaculation, no. I teach a mix of self defense and health sciences and I can prove beyond a doubt (to my students) that the orgasm is important for good health while the ejaculation, if too much too often, can be bad. Anyone who has a deep understanding of human physiology will know that there are a vast amount of concentrated nutrients in the sperm and seminal fluid. Letting it out of the body by ejaculating is an instant loss and will cause the body to rob from the rest of the body to get enough of the nutrients to make more sperm and seminal fluid ... especially vitamin B12 from the vitrious fluid in the eyes (hence the saying "stop or you'll go blind"). While the orgasm is great for the health, the loss of fluid can be so bad that most religions have a celibacy rule so the religious leaders do not suffer from the adverse effects of sperm/seminal loss. Although the effects are not usually visible or detectable to the younger men, if the frequent loss continues for many decades, the effects become much more noticable, but by then, it is too late to fix the problem. Taoism teaches people how to enjoy the feelings of the orgasm while avoiding the fluid loss problems. Check out the book, "Taoist Secrets of Love: Cultivating Male Sexual Energy" by Mantak Chia (or just google the man's name) ... or his follow up book, "The Multi Orgasmic Man" ... in them he explains exactly how to gain the internal self controls needed to maintain self control during orgasm. With most men, the orgasm results in a sensory overload and loss of control and then the ejaculation happens because it can no longer be controlled. With the male, orgasm and ejaculation are two completely separate events, they just happen so close together it is often assumed they are the same. Once a deep level of internal self control has been developped, the man may make a conscious choice of having sex that is either recreational or procreational. The procreational sex definately need the ejaculation, but the recreational sex does not.

I have read that the risk of testicular and prostate cancers are increased if a man doesn't regularly ejaculate and 'clean out' the system. In terms of mental health, I think that orgasm/ejaculation is neccessary to release built up tension.

According to the book "Making A Good Brain Great", regular sexual activity helps both cardiovascular and brain health. Plus it's fun...;-D.... http://www.amazon.com/Making-Good-Brain-Great-Performance/dp/1400082099/

I hope not... My health is bad enough... I'd hate to see how bad it would be if I stopped ejaculating... (although, maybe my carpal tunnel would go away... LOL!)

Not necessarily for women...

Orgasm in men and women are very healthy. Its been proven that regular orgasms actually help increase your immune system, reduce stress, relieve pain and generally create a feeling of well being. When a woman orgasms her body produces a hormone called oxytocin which the body needs to reduce and regulate prolactin which if excessive can actually enhance breast cancer and tumors. Oxytocin natuarlly regulates this. The better the orgasm the more oxytocin produced. In a study in the UK over a 10 year period, about 2,000 people were studied and it was found that the ones that had frequent regular orgasms 2 or 3 or more a week, had after the ten years approx a 50% lower mortality rate than those that had less than 2 or 3 orgasms a month.

Is it possible for a man to have an orgasm but not an ejaculation?

In the past ejaculation frequency was associated with a persons health. It was thought that if a person ejaculated too much that they would become ill. Times have changed, today we know more about the human body than in the past. Ejaculation does not in itself make one feeble. The male body is constantly replenishing sperm. What can cause problems is risky sexual behavior,poor overall health and a person's mental and emotional health. Like any other physical activity you enjoy if you over do it you will get tired and need to rest. Sex is no different, if approached in a healthy, balanced way sexual activity is good for a person's health. Another factor is our environment today. While retaining ejaculate in the body was not considered harmful 60 years ago, recent information has shown that because of the increase in toxins in our daily life that enter our body. Retaining fluids might encourage cancer and other tumorous growths in the reproductive system. This would explain why we see a sharp increase in ovarian , breast, anal, prostate and other cancers. Unless, we change our views on these matters we will continue to see increasing cancers and other diseases that are a result of lifestyle and ignorance regarding our bodies and how to keep them healthy.

http://www.webmd.com/prostate-cancer/news/20040406/frequent-ejaculation-prostate April 6, 2004 -- Frequent ejaculation, whether it happens during sexual intercourse, masturbation, or a dream, isn't likely to increase men's risk of prostate cancer. In fact, new research suggests it may have the opposite effect and help protect the prostate. Researchers say it's too soon to recommend that men change their sexual habits in an attempt to lower their prostate cancer risk. However, the study raises interesting questions about the role of ejaculation and sexual behavior in the development of prostate cancer. Previous studies have linked frequent sexual activity to a higher risk of prostate cancer, but this new, large study found ejaculation frequency was not associated with prostate cancer risk except in the highest category. Men who ejaculated most often actually had a 33% lower lifetime risk of prostate cancer, and this relationship grew stronger as men grew older. For example, men who reported 21 or more ejaculations per month in their 40s had a 32% lower risk of prostate cancer later in life compared with those who reported between four and seven ejaculations per month. Men who reported more than 21 monthly ejaculations in the previous year had a 51% lower risk of prostate cancer. Overall, an average of 21 or more ejaculations a month during a man's lifetime decreased the risk of prostate cancer later in life by 33%. And each increase of three ejaculations per week during a man's lifetime was associated with a 15% reduction in prostate cancer risk.

well it is surely a stress reliever either way
