How does age affect fertility?\nMore and more people are delaying having children until their late 30s or 40s. But as you age, so do your ovaries and the eggs inside them. You cannot see or feel these changes, and they happen faster than you may think.\nA woman's peak reproductive years are between the late teens and late 20s. By age 30, fertility (the ability to get pregnant) starts to decline. This decline happens faster once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely.\nAge affects eggs:\nYou begin life with a fixed number of eggs in your ovaries. The number of eggs decreases as you get older. Also, the remaining eggs are more likely to have abnormal chromosomes. And as you age, you are more likely to have developed health conditions that can affect fertility, such as uterine fibroids and endometriosis. A man’s fertility also declines with age, but not as predictably.\nIf you are \nolder than 35\n and have not gotten pregnant after 6 months of having regular sex without using birth control, talk with your doctor about an infertility evaluation. If you are older than 35, an evaluation is recommended before you try to get pregnant. This advice is especially important if you have a problem that could affect fertility, such as endometriosis.\nDuring an evaluation, you have physical exams and tests to try to find the cause of infertility. If a cause is found, treatment may be possible. In many cases, infertility can be successfully treated even if no cause is found. But the chances of success with these treatments decline with age.\nPrenatal screening tests, if you are taking\n IVF treatment,\n can assess the risk that a pregnancy will be affected by a specific birth defect or genetic disorder. Also, multiple pregnancy is more common when you are older. As the ovaries age, they are more likely to release more than one egg each month. Some fertility treatments also increase the chance of a multiple pregnancy. Although multiple pregnancies can be healthy, these pregnancies can increase the risk of preterm birth.\nAt GarbhaGudi IVF Centre, we are pleased to have achieved some of the highest IVF success rates in the entire country. Unlike some fertility clinics with high success rates, we have achieved these rates while working with patients of all types, including those with complex fertility issues and women who are aged 35 and older. This latter category of patient can be particularly challenging to work with because even women without fertility issues begin to see their chances of becoming pregnant dwindle after they reach the age of 35.\nThe closer a woman is to the age of 40, the more likely her age alone may be considered a contributing factor in her infertility if a couple has tried to achieve conception unsuccessfully for six months or longer. At this point, it is highly recommended that such couples meet with an experienced fertility expert.\nOur doctors can discuss the relationship between \nIVF\n and age during consultations so that such couples can understand both the benefits of treatment and the possible hurdles that could prevent them from achieving a successful pregnancy.\nHow are age and IVF success rates related?\nIn general, by the time a woman reaches the age of 35, her peak years of fertility are behind her. Of course, this is not a hard-and-fast rule. Some women remain perfectly fertile at the age of 35 while others, unfortunately, reach their peak well before that age. However, usually by this time, women have a smaller number of eggs in their ovarian reserve, and those eggs that are left are generally of lesser quality than they had been when she was younger. In essence, this represents a double threat to her chances of becoming pregnant while increasing the risk of miscarriage if she does conceive.\nConsidering all of this, most women aged 35 and above are faced with at least some fertility issues. While these fertility issues may not preclude her from becoming pregnant, they certainly can interfere with a successful pregnancy. If other male or female infertility factors are present, age may be the factor that ultimately prevents conception.\nIn such cases, IVF often offers the best chance of a successful pregnancy. While IVF success rates diminish with each year that a woman is above the age of 35, the age of the male partner also can influence IVF success rates, too, if not as drastically. A couple is still far more likely to achieve pregnancy through IVF than without treatment.\nIf a woman does not have eggs of sufficient quality, we may suggest the use of donor eggs in IVF treatment. This could increase the odds of success considerably, especially in patients over the age of 35- 40.\n

While a slight decline begins in the early 30s, the most significant drop-off typically occurs at \nage 35\n.

As women age, the remaining eggs are more likely to have chromosomal abnormalities. This doesn't just make it harder to get pregnant; it also increases the risk of miscarriage and genetic conditions.

Yes. Age affects sperm quality, volume, and motility, which generally decline after \nage 40–45\n. Research suggests that advanced paternal age can lead to a longer time to achieve pregnancy and a slightly higher risk of miscarriage and certain neurodevelopmental conditions in children.\n

It depends on age: Under 35: Try for one year of regular, unprotected sex. 35 to 39: Seek a consultation after 6 months. 40 and older: It is recommended to see a fertility specialist immediately to maximize your remaining fertile window.\n

IVF is the most effective treatment for age-related fertility decline because it allows doctors to select the healthiest embryos. However, IVF success rates are still influenced by age.
