The Chances of Becoming Pregnant For most couples attempting to conceive, the chances of a woman becoming pregnant in any given month range from 15% to 25%. However, women who want to get pregnant quickly may wish to try and plan their pregnancy so that it occurs within the first 12 months of marriage or relationship stability. According to the Mayo Clinic, using birth control for this purpose is called "timing infertility treatment."
When we talk about chances of pregnancy, we are talking about the chances of you becoming pregnant if you are trying to have a child. If you already know you are expecting, then you already have a child. So really, your chances of becoming pregnant are 100%. But since most people want to be surprised when they find out they are pregnant, it's best to just assume that you have less than a 100% chance every day.
So how likely is it that I will get pregnant? That depends on how likely you are to become pregnant. If you are younger than 35 and have not been through menopause yet, your chances are very high. If you are older than 35 or have gone through menopause, then your chances go down. But even though your chances are lower, they still average out to around 15%-25% per month.
In general, your odds of conception are low, but statistics don't tell the whole tale. Many factors, including age, health, and any illnesses you or your spouse may have, impact your individual odds of conception. The reality is that, even if everything appears to be in place for success, there is always some element of luck involved!
Your chances can also vary depending on how long you've been trying to get pregnant. If you haven't tried for a while, then you might want to start up again. It's important to understand that fertility declines with age for both men and women. For women, this means that your chance of conceiving increases as you get older. For men, this means that your ability to produce healthy sperm decreases.
There are several ways of estimating the chances of you getting pregnant. A common method is called "the baby maker" or "calculating the odds". This involves multiplying your age by 100 and dividing it by your partner's age plus 7. So, if you're 35 years old and your husband is 45 years old, their odds of conceiving a child are 20%. (100 x 35/45 + 7). Another way is to look at it this way: if you were 40 years old and your husband was 50 years old, their odds of conceiving would be 12% because 200/42 = 4.8.
Women aged 40-41 years had a 53% decreased risk. Each month, women under the age of 30 have a 20% chance of becoming pregnant spontaneously. By the age of 40, the likelihood of becoming pregnant is roughly 5% every month. Dr. Melanie McDowell discusses what happens to eggs (also known as oocytes) as women become older.
The number of viable eggs drops with age because of radiation exposure, cancer treatments, and other factors. However, this does not mean that women cannot get pregnant in their 40's or even 50's. Many women in these ages do get pregnant each year. It's just less likely than it was for younger women because there are fewer eggs to start with. But if they do get pregnant, they can expect about one third of their embryos to be damaged by age-related issues such as free radicals and telomeres shortening.
Women over the age of 40 should discuss with their doctors how much protection they need from contraception. Some forms of contraception may not work as well for women over 40 because it takes time for hormones to change how tissues react to certain medications. For example, birth control pills may not be as effective at stopping sperm from reaching the egg after menopause because the body no longer produces estrogen which helps keep sperm away from the egg. Women over 40 can also experience changes in brain function and blood flow that can affect how they respond to certain medications. These factors must be taken into account when choosing a form of contraception for women over 40.
