The best odds to conceive is in the 20’s. One study found that women between the ages of 19 and 26 have a 50% chance of getting pregnant on any given month if they have unprotected sexual intercourse on the most fertile day of their menstrual cycle. The odds drop to 29% for women ages 35 to 39 face, according to the study. Tracking your cycles is also a good way to detect any potential fertility problems. If the cycle or irregular or not showing any signs of ovulation, then a practioner shpuld be consulted. Failure to conceive after 1 year should alert a couple to seek a fertility evaluation. Infertility is less comm,on in couple it can and does occur. Ensuring good health is always a paramount idea such as maintain a healthy diet and avoiding smoking and above all practicing safe sex when not trying to conceive. The data shows that women who have one episode of PID reduces their fertility by 12%, 2 episodes by 25% and 3 episodes by 50%.
Fertility in the 30’s will generally decline but will vary on a case-by-case basis. Fertility begins to decline faster after the age of 35 and most practitioners recommend that trying to conceive for up to six months is a good technique. The age of the male partner is another consideration to be realized.
Male fertility declines with time as well, but at a slower rate than female fertility. Therefore, egg freezing is another viable solution before age 35 if pregnancy will be attempted in the future. However, its important to understand that freezing eggs is a good option although not a guarantee of success.
Some fertilized eggs will not develop into healthy embryos and some eggs don’t fertilize at all. The consideration of fertility in the 40’s is another dilemma a woman faces. Fertility success rates are significantly lower for older couples. While one in three individuals might experience infertility in their early 40s, that still means that two in three do not. Therefore, freezing eggs with a combination of IVF treatment, can be an option for having a baby for older couples. The risks do increase for those in the 4os that include gestational diabetes, premature labor and birth, high blood pressure, and preeclampsia, along with the higher chance of miscarriage.
In the 50 and beyond group, menopause is then encountered. This means eggs are no longer viable or ovulating, but the uterus may still be fertility-ready. The possible risks are greater than any other group so a fertility specialist must be consulted to determine the ramifications for each client.
In conclusion protecting overall health such as having safe sex, avoiding habits like smoking, and seeing a doctor if your cycles are irregular are all ways to take care of fertility.
