From the website: 'In clinical programs of assisted reproduction involving
infertile males, it is essential to obtain semen of maximum quality. To
evaluate ways of achieving this objective, and to assess the fertilizing
capacity of the sperm, six semen samples were collected from each of 38
infertile men via masturbation. Six more samples were then collected from
each man at sexual intercourse using a semen collection device (SCD).
We confirmed that the volume of seminal plasma, total sperm count, sperm motility, and percentage of normal spermatozoa were significantly higher in samples collected at intercourse than masturbation, as reported previously. In addition, the markers of the secretory function of the prostate and the outcome of sperm function tests were significantly higher for the samples collected at intercourse.
There were no significant differences in the serum concentrations of gonadotropins, or in the serum or seminal plasma concentrations of testosterone, before or after masturbation or sexual intercourse. Therefore, the differences in prostatic secretory function and semen may not be attributed to differences in hormonal levels.
Semen collection during intercourse using an SCD appears to be the method of choice for selecting semen samples for artificial insemination.
Although masturbation is the standard method for the collection of a sperm
sample, both for diagnostic and therapeutic purposes, other approaches have
been described and assessed. Production of semen using specially designed
condoms (Silastic seminal fluid collection device - SCD) has been shown
to result in samples with better laboratory characteristics than samples
obtained after masturbation or coitus interruptus. However, this has not
resulted in a general acceptance and use of this approach, except in special
circumstances where masturbation is impossible or unacceptable.
...The conclusion of all this data is should evidently be that, for reasons of artificial reproductive technology, masturbation as a method for semen collection should not be recommended, and be replaced by coitus with a SCD. ... An excellent alternative where masturbation is not possible or refused (due to religion).

The work will not just benefit humanity, it will profoundly enhance your own sexuality as you learn more about our complex and diverse sexual evolution.
We seek help in finding the latest scientific (evolutionary) research on our biological and cultural sexual evolution and distributing content (overviews / summaries) to relevant pages.
This site is well respected. We are listed as the Top Philosophy Website on the Internet with around 600,000 page views each week. So your contributions will be seen and read, and will be providing humanity with a great source of wisdom about a very important subject (that currently suffers due to cultural / religious myths).

Analyse any human emotion, no matter how far it may be removed from the sphere of sex, and you are sure to discover somewhere the primal impulse, to which life owes its perpetuation. ... The primitive stages can always be re-established; the primitive mind is, in the fullest meaning of the word, imperishable. ... Mans most disagreeable habits and idiosyncrasies, his deceit, his cowardice, his lack of reverence, are engendered by his incomplete adjustment to a complicated civilisation. It is the result of the conflict between our instincts and our culture. (Sigmund Freud)
