In January 2017, a group of researchers at Harvard University published a study that demonstrated that a woman’s age at first intercourse and her age at ovulation did not predict her likelihood of pregnancy, according to an Associated Press story.
But if a woman was 20 when she got pregnant, for example, it would be a big deal if she was 35 in 2019.
And if a man was 28 at the time, he would probably be too old to get married.
So while it may seem like you have to wait a little longer to have sex, it’s not really as bad as it sounds, said Dr. Mary Anne Franks, the director of Harvard’s National Institute of Reproductive Health.
She said it’s more important to get a lot of sperm, even if you’re only in your late 30s.
And the longer you wait, the better chance you have of conceiving.
Franks and her team found that if a couple had intercourse in late June or early July, it was about 70 percent more likely for the woman to become pregnant if she were 40.
So it may sound like the odds are stacked against you if you’ve been in the middle of pregnancy for awhile, but Franks said a woman can have intercourse at any age.
She told ABC News, “There are a lot more people than you might think.
So, it doesn’t make you a bad person if you don’t want to get to it, but there are a bunch of reasons why it might be important to do it.”
Franks said her research also showed that a man’s age does matter in predicting his likelihood of conceving a child.
If a man is at least 30 when he gets pregnant, the odds of having a child with a girl is about 20 to 30 percent higher than if he’s in his late 20s or early 30s, Franks said.
In her study, Franks and a team of researchers analyzed data from 2,400 couples that had had intercourse before or since their 30s and had had more than 10,000 spermatozoa (eggs) collected from them.
They found that the more fertile a man looked at his own age at the beginning of his first sexual encounter, the less likely he was to conceive.
So a man who was 25 at the start of his last sexual encounter was at an even higher risk of conceting his child if he was 40 at the end of the year.
It was the age of the most fertile semen in the study, which Franks said is a little hard to explain.
The researchers said they believe their results indicate that men who have had more partners and ejaculated earlier are more likely to be fertile.
But they are not saying that fertile men should be waiting to have a baby for another 10 years or so.
Franks said she doesn’t think the research has shown that a longer wait is necessarily better for a woman, but she said her findings are an important reminder to have regular sex in order to be able to have children.
But there’s a caveat.
Franks’ study focused on spermatozoids, not embryos, and she said the team also did not include any data on how long spermatozes might take to develop in a woman.
It’s possible that men can wait longer, but the longer it takes for sperm to develop, the more likely it is that the woman won’t conceive, Franks told ABC.
Franks believes that delaying pregnancy and conceiving a child can be achieved by having more sex, as well.
“Sex is the key to pregnancy, but having more is the most important part,” Franks said in an interview.
