Researchers at Bristol and Brunel Universities evaluated 8,500 couples to determine the impact of age on the length of time it took to conceive. They discovered that while only 8 percent of men younger than 25 fail to impregnate their partner after a year of trying, that number grows to 15 percent after age 35. The study suggests that paternal age has its role in fertility.
The sperm can live for about 72 to 120 hours; however, the egg only lives about 12 to 24 hours after leaving the ovary. This causes missed opportunities and may take a couple several months to conceive, however, such a delay is normal and one should not be considered infertile. Planning to have sex at the right time can increase the chances of conception.
Obesity is also a cause of infertility and low testosterone levels in men. A study of women found that those whose body mass index (BMI) was above normal took twice as long to get pregnant as those with a normal BMI. Weight loss for those who are overweight or obese can improve fertility and pregnancy outcomes. Being significantly underweight can also alter hormones and be a cause of infertility.
Very high temperatures can be harmful to sperm and that is why men have recently been asked to avoid wearing briefs fearing decrease in sperm count or concentration. According to two recent studies, choice of underwear does not matter as it does not heat things up.
The method of contraception that a woman has used may also impact conception. Women who used progesterone injections of depo-provera may have to wait for normal fertility to resume after they've stopped using the drug for six to nine months or even a year. It may take women who use Lunelle, another injectable form of birth control, six months to a year to have a normal menstrual and ovulation cycle. Oral contraceptives help to preserve fertility; pill users have a decreased risk of illnesses that harm fertility, such as endometriosis, PID, and ectopic pregnancy. So, choose your contraceptive considering the time when you wanted to conceive.
Although, aiming for the deepest penetration and maximum cervical contact makes sense, the sex position cannot increase the chances of conception. Lying down after intercourse to keep the sperm inside you may help a little, but there's absolutely no reason to perform acrobatics to help the sperm swim further. It doesn't help at all.
One in 10 healthy couples of reproductive age experiences fertility problems. The biggest factor that impacts fertility is age. For healthy women, fertility peaks in their mid 20s, begins declining at age 27, then nosedives around age 37. If you are in your mid 30s or older and trying to conceive, you need to be very sure when you're ovulating and have sex accordingly. So, even healthy men or women may find themselves helpless when trying to conceive.
Lifestyle factors like smoking, drinking too much, taking drugs and eating processed foods, can increase the number of free radicals floating about in your system. A recent study suggests that the concentration of sperm in male smokers has been found to be lower than in non-smokers. So, over a period of time, your lifestyle may affect your fertility.
