Why age matters for men and women who want to have a family. We all know someone who had a healthy baby in their late 30s or early 40s. But of all people who try for a baby at a later age, many will not have the baby they hoped to have. Across a population, women younger than 35 and men younger than 40 have a better chance of having a child than people who are older. This is true for natural pregnancies and for pregnancies conceived through assisted reproductive treatments such as IVF in-vitro fertilisation.

Perhaps it would be simpler if women could go it alone. After all, not all animals are so hung up on sex. As New Scientist reported earlier this month, virgin births in nature are common. So could humans learn this biological trick, allowing women to fall pregnant on their own schedule — without men getting in the way? Ten years ago, Japanese researchers unveiled a mouse that had two mothers but no father. Named Kaguya, after a mythical moon princess born in a bamboo stalk, she was created in a laboratory by combining genetic material from two female mice.

Some female sharks isolated from males can become pregnant Thinkstock. With a little bit of help, stem cells from a female donor can be induced to grow into sperm cells — something that would never normally occur. So it might be possible to create a child from two mothers, each of whom contributed half the genetic material.

Even if researchers could clear that roadblock, a partner is still required. In the wild, most females that resort to parthenogenesis do so only when it is strictly necessary — typically when they have become isolated from any males. Likewise, parthenogenesis in sharks came to light after several incidents in which lone females kept in aquariums inexplicably fell pregnant.

But these are testing times for the animals. They lose the genetic diversity that keeps a population healthy, he explains.

The price they would pay, however, would be an alarming genetic bottleneck. When a gene pool is small, the risk of birth defects and other illnesses rises. Take the European royal families, nearly all of which are in some way related. Prognathism, a deformity that causes the lower jaw to jut out, is so common within the European royals that they lent the condition its common name, the Habsburg lip. In a normal population this condition would be diluted out, but in the tightly-knit European royals it emerged again and again.

Just as inbreeding reduces genetic diversity of a population, self-fertilisation can reduce the genetic diversity of your offspring. If you chose to reproduce entirely on your own, your child would only have one parent, and thus half the genetic diversity available to a normal child. Each subsequent generation of single-parent reproduction would continue that trend, with the increasing risk that normally hidden defects would surface. In this manner, your offspring would suffer a collapse in genetic diversity far worse than any European royal faced.

Sperm is usually necessary for reproduction - but it can come from other sources than men SPL. So, if a woman was serious about giving up on sexual reproduction, it would be prudent to set aside some genetic material, a master copy that descendants would use to replace the diversity lost in intervening generations. It would certainly make for a very confusing family tree. Unfortunately this leapfrogging trick only forestalls the inevitable.

Embrace the idea of virgin births exclusively, and your children will only ever be a fading echo of yourself. Share using Email.

What Men and Women 35 and Older Must Know About Fertility, Infertility, and Getting Pregnant

Both men and women over age 35 experience a decline in fertility. But age-related fertility declines are more pronounced in women. Fertility, or the ability to conceive and have children, changes with age. Around 1 in 8 couples have trouble getting and staying pregnant, according to the National Infertility Association. Before pregnancy can occur, fertilization must take place.

Error: This is required. Error: Not a valid value. In every couples trying for a baby, the woman will get pregnant within one year in 80 to 90 cases.

Trying to get pregnant isn't always easy and can require some patience. If you want to speed up the process and get pregnant as soon as possible, here are some helpful steps you and your partner can take. Researchers have found that following a " fertility diet " may increase an, otherwise healthy, woman's chance of getting pregnant. They reported that women who cut back on sugar, got their iron from leafy greens or supplements, and ate more vegetable-based proteins like beans and nuts compared to meat were less likely to have issues with infertility.

Meet the Men Having Sex With Strangers to Help Them Have Babies

Sometimes it costs thousands of dollars for a successful pregnancy. But now, those services have gone online, and at the click of a mouse, donors make their sperm available by offering to have sex for free. It's a surprising -- and some say unconventional -- method of making a baby called "natural insemination. Donors connect with women on the Internet who want to become mothers "the natural way," because the recipients believe having sex maximizes their potential for getting pregnant. When he is not working as an Internet entrepreneur, Joe travels around the country to impregnate women from every walk of life. Sometimes Joe ships his sperm for artificial insemination, but he often donates by having sex. When asked how many children he expected to have over his lifetime, Joe's answer was surprising. The other donors I know who have a lot [of children] are up there around the range. I'm standing on the shoulders of giants. Kyle Gordy is also a donor.

Timing of sex for pregnancy

Back to Pregnancy. Yes, although the risk of getting pregnant in this way is very low. If you want to avoid getting pregnant, you should use contraception. A man's semen the liquid produced when he ejaculates or "comes" contains millions of sperm.

Perhaps it would be simpler if women could go it alone.

Can I get pregnant if I have sex without penetration?

Although there are a number of days in the month when you are more fertile, there has not been a lot of high-quality research into whether timing sex around the 'fertility window' increases your chances of pregnancy. Having regular, unprotected sex every 2 to 3 days without contraception will give you the best chance of success. More than 9 out of 10 couples will get pregnant within two years.

As women are the ones who get pregnant there is a lot of attention on their health and wellbeing.

Breathing in the smoke from your cigarettes can damage their ability to get pregnant.

How to improve male fertility

It takes two to make a baby. Although a woman will carry and deliver the child, a man also has a crucial role in pregnancy. For fertilization to occur, his sperm must be healthy and strong to reach and penetrate the woman's egg. A problem in any step in this process can prevent pregnancy.
