What is IVF?

In vitro fertilization or IVF as it is called, is one of the types of Assisted Reproductive Techniques, which uses a combination of medicines and surgical procedures that help sperm fertilize an egg and implant the fertilized egg in the uterus.

IVF Success Rate in India

IVF success rates in India have increased over time, which is a result of improvements in medical technology and a rise in the level of knowledge among reproductive specialists. The overall success rate for IVF in India normally ranges from 30% to 50% per cycle. Success rates might vary depending on several circumstances, including the age of the woman, the quality of the embryos, and underlying medical issues.

Improved laboratory procedures, a greater comprehension of the needs of individual patients, and a rise in the use of pre-implantation genetic testing to identify viable embryos are all factors that have contributed to the success rates increasing. Furthermore, patients from all over the world looking for affordable solutions have been drawn to India because of the low cost of IVF treatments there.

It’s significant to remember that success rates can vary from clinic to clinic. Prospective patients should do their homework and speak with knowledgeable fertility doctors to learn their specific odds of success given their particular circumstances.

What are the factors that affect the IVF success rate? How can it be increased?

If you go by the numbers, the success rate for an IVF pregnancy is about 30% with live birth rates being a little lower than 30%.  There are multiple factors that could affect the success rates of IVF and there are multiple ways to improve the chances of you conceiving using simple lifestyle changes. As you are someone who is looking forward to an IVF cycle, you should be aware of the same.  There are also ways to mitigate the risks that are associated with the mentioned factors and we shall also increase our awareness of the same.


Your age is one of the most important IVF success factors to consider. While younger women have higher chances of IVF success, the reduction in the number of eggs and the reduction in the quality of the eggs as you age tend to be the reasons behind the reduction in the success chances of IVF treatment in older women. In fact, the live birth IVF success rate for women who are under 35 and who start an IVF cycle is 40 per cent. However, the success rate for women over age 42 is 4 per cent.

Previous pregnancy and partner:

One more important factor to consider during IVF is whether or not you were pregnant previously and if it was with the same partner. The probability of success is much higher if you were previously pregnant with the same partner that is undergoing the IVF treatment. Factors such as having a history of recurrent miscarriages or previous pregnancy with a different partner may reduce the chances of IVF success.

Type of fertility problems:

While some male infertility problems do impact IVF success, factors like uterine abnormalities, exposure to DES, or fibroid tumours that you might be facing, also decrease the likelihood of your success with IVF. Very important to know: IVF success factors are dependent on ovulation. Ovarian dysfunction, like high FSH levels which indicate a low ovarian reserve, may also reduce the chances of your IVF success.  There could be a need for you to take large amounts of ovulation stimulation drugs. When both partners are infertile with lower chances for IVF success, factors such as the length of time you have been infertile are important to consider. The chances of IVF success decrease with the amount of time a couple has been infertile.

Use of donor eggs:

Donor eggs are a significant consideration, especially if you are over 35-40, as there may be a higher rate of IVF success. Factors such as egg quality and age of the donor are important. Using donor eggs from younger women may increase the chances of pregnancy for women over 40. 2011 findings show a 55 per cent live birth success rate with a fresh donor egg/embryo transfer.

Lifestyle habits:

Stop smoking if you want to improve your chance of having a baby. In fact, many times the woman is required to stop smoking at least 3 months before starting IVF treatment.

  • Smokers require higher dosages of fertility drugs to stimulate their ovaries
  • Smokers have lower implantation rates than nonsmokers
  • Women who smoke require almost twice as many IVF attempts
  • Women who smoke experience more failed fertilization cycles
  • More IVF success factors to mull over include losing weight if you are overweight or obese.
  • Women who are overweight have an increased risk of infertility as well as miscarriage. Overweight women also have less IVF success with fertility treatments than women of normal weight. Underweight women are also at greater risk of having success with IVF.

Bottom line: aim to stay within a healthy weight range.

Fertility clinic:

The centre you choose to perform the IVF treatment can greatly affect your IVF success. Factors to think about when reviewing the success rate of fertility centres include:

  • The training and experience of the IVF clinic and staff
  • The live birth rate per IVF cycle started
  • The rate of patients pregnant with multiples (twins, triplets or more)
  • The laboratory used by the clinic and the qualifications of their staff
  • The types of patients accepted at the clinic, more specifically their age and fertility problem
  • Keep in mind that some clinics are more willing to accept patients with a lower chance of IVF success or they may specialize in particular treatments.

IVF Success Rates By Age

Fertility typically declines with age and along with it IVF success rate also reduces. It happens because the quality and quantity of eggs decrease with age which directly affects fertility and causes difficulty in conception. The success rate may also vary depending on the age –

  • IVF success rates under 35

It is said that men and women are more fertile in their 20s and have a higher success rate of pregnancy compared to people in their 30s. The success rate may vary from one fertility clinic to another depending on the specialisation of the doctor and the type of cycle opted for assisted reproduction. The average success rate is generally between 25% to 35% for women under 35.

  • IVF Success rates over 40

The success rate of assisted reproduction and natural conception typically minimize for women over 40. According to research, it is believed that the average success rate of IVF for women in their 40s is usually 3% to 4% per cycle. The chances of conception get really low and women may experience trouble getting pregnant through IVF or even naturally.

IVF Success Rate By Number OF Embryos

The number of embryos transplanted during in vitro fertilisation (IVF) can affect the success rate of the process. The ideal number of embryos to transfer can, however, change depending on the woman’s age, the quality of the embryos, and any underlying medical issues. Fertility doctors are frequently consulted when deciding how many embryos to transfer in order to increase the likelihood of a healthy pregnancy while lowering the danger of multiple pregnancies, which can pose health risks.

In some situations, particularly for older women or those who have a history of poor IVF treatments, transferring a greater number of embryos can boost the likelihood of a successful pregnancy. It also increases the likelihood of multiple pregnancies, which can have negative health effects on both the mother and the unborn children. Many clinics try to balance getting pregnant with preventing multiple births.

It’s crucial to understand that while adding more embryos may raise the likelihood of success, the hazards should also be considered. The right number of embryos transfer is decided by fertility professionals in close consultation with patients based on their unique situations and medical needs.


Hence, if you suspect you might have issues with fertility it is always advisable to not delay making a visit to a trusted doctor and address the same. The sooner you try and address the issue, the less severe the problem could be. You’re just a doctor visit away from creating a happy family that you have always dreamt of.
