Submission + - More sex... the answer for fertility problems. (bbc.co.uk)
kashif.ahsan writes: "From the article,"Some men should have sex every day to maximize the chances of getting their partner pregnant, researchers say." The article goes on to suggest that waiting for a week or two before having sex again may raise the number of sperms at the time but the real problem is not the number. The "DNA damaged sperms" are bound to fail more even if they are in larger number, so its a question of quality vs quantity. The experiment allowed for 42 men to ejaculate daily for seven days and it turns out that their sperms were less damaged(20% as opposed to 30% before), though smaller in overall number."
