There has been some debate over how frequently a couple should have sex when trying to conceive. It was once thought that abstaining from sex for a few days before ovulation helped build up a man’s sperm count, improving the chances of conceiving. Daily sex was believed to reduce a man’s sperm count so some experts advised against it.
Reuters reports that having daily sex is now believed to be a good thing for couples trying to conceive. A new study by Dr. David Greening of Sydney IVF (an Australian IVF clinic) disputes the idea that abstinence helps to improve male fertility and instead recommends daily sex.
Here is why. According to Dr. Greening, frequent sex reduces the length of time sperm are exposed to molecules inside the man’s testicles that could damage sperm. Basically, by getting sperm out of the man’s body every day, damaged sperm are removed and the new healthy sperm are ejaculated before they can sit too long and become damaged.
Still, frequent ejaculations may reduce semen volume but this is not an issue for most men. Dr. Greening suggests, “that couples with relatively normal semen parameters should have sex daily for up to a week before the ovulation date."
