Casual sex produces better quality sperms

Men produce better quality sperm, ramp up the sperm count and orgasm faster during causal sex encounter with a new partner, according to a new study by a team from the College of Wooster in Ohio, that could change the way infertility is being treated. Men produced higher quality ejaculates when exposed to novel, rather than familiar women, the researchers found.

‘Men also ejaculated more quickly when viewing a new woman after being exposed to the same woman repeatedly,’ according to a study published in the Journal of Evolutionary Psychological Science, the team asked 21 men to provide semen samples while watching seven different explicit three-minute clips of a male and female having sex.

The participants used the same private room to produce the semen with 48 to 72-hour breaks between each session. The first six clips used the same male and female actor while the seventh clip used the same male actor but involved a different female.

Apart from the quality of sperm produced, the length of time it took to ejaculate was also recorded. The researchers found that the men produced healthier, higher volume sperm in a shorter amount of time when exposed to the seventh clip featuring a different looking female.

‘An increase in the total number of motile sperm may result in higher likelihood of fertilisation and greater ability to compete with other male’s sperm,’ they wrote. Whereas a decrease in the time to ejaculation may decrease the likelihood of an extra-pair copulation (with a partner that is not your own) being detected.

The findings can help in fertility treatments since ‘ejaculate samples used to test for infertility are often collected with the use of images depicting women other than the man’s partner’.

‘Our findings are the first to demonstrate that men’s ejaculate behaviour and composition change in response to novel female stimulus,’ the authors concluded.

Casual sex  which is uncommitted, unemotional and purely carnal, takes many forms including the one night stand, the cereal sex, the booty call, sex by appointment, recreational sex as some one once said “every great athlete needs practice”.

Only 40 per cent of the women orgasm during causal sex, compared to 80 per cent of the men.  Researcher interviewed 24,000 students in 21 colleges over a five year period and discovered 75 per cent of women orgasm when having sex with a committed relationship. One night stands are known to  have created  heart ache and regret and a new research has raised the question whether women should bother with them at all. The new study also found that casual sex is more satisfying for men that women.  Dr Kim Wallen an expert in female desire at Emroy University said ” the notion that sexual liberation is an equal playing field  where men and women has equal access to causal sex is completely wrong. Researchers at the Indiana University and the Binghampton University interviewed 600 college students about their sex lives. Dr Justin Garcia said ” the fact that when having causal sex not everyone is having a good time”.
