Success rates vary from clinic to clinic all over the world depending on population to population. Similarly, it varies from clinic to clinic in India. There are several factors that determine the success in an IVF treatment. Some of the factors are mentioned below: 

Type of Fertility Problem

There are some medical conditions where the success rates are very good while in some the success rates are not so good for such as tubal blockage cases give good results in IVF as compared to recurrent miscarriage condition or thin endometrium. In women, the uterine abnormalities, exposure to DES (a synthetic estrogen), fibroids and long-lasting effects of latent tuberculosis also affect IVF success rates negatively.

 While some male factor infertility may also impact the IVF success rate but with the advent of ICSI and other sperm selection procedures, the effect on the success rate is sufficiently reduced.

Some other factors affecting fertility rates are: 

  • Age of the Patient

The age of the patient is important in determining the success rate of IVF. The older the women the lesser the chances of success in IVF. The important determinant in this is the age of the egg. Both the quantity and quality of the egg goes down with age. An experienced doctor decides about the protocol of ovarian stimulation, the number of embryos to be transferred and so on. Doctors generally can transfer up to 5 embryos in such cases. 

  • Duration of infertility

The duration of infertility is also an important determinant of the success rate in IVF. As the duration of infertility is closely tied to the increase in the age of women, there is a corresponding decrease in the success rate. The way out may be egg donation. 

  • Previous Pregnancy or Recurrent Miscarriage

History of previous pregnancy and recurrent miscarriage can be a cause of caution even before the treatment is started. Such patients are slightly difficult and the success rate in such cases is low.  It is difficult for such patients to deliver a live baby.  

  • Ovulation Dysfunction

Ovarian dysfunction is also an important factor determining the success rate. Patients with a high level of FSH and low levels of AMH, where, the hormone required for stimulation is high, the success rates are generally low. 

  • Dual Infertility Factors

In cases where both husband and wife have an infertility factor, the chances of success in an IVF cycle are very low. Such cases also lower the success rate in such cases. 

  • Use of Donor Eggs /Embryos

In case the women are over 35-40 years of age, donor eggs from a young female are a good alternative for success in the IVF cycle. Also, the quality off egg quality and patient’s age are important. The success rate with donor eggs in patients over forty years of age increases the success rate to 55%.

In the case of dual-factor infertility, the embryo transfer offers a good chance to improve the chances of success in IVF. The success rates are as high as egg donation in embryo donation. 

  • Lifestyle

Lifestyle and habits have a role in the success of IVF treatment. 

  • Smoking

Stop smoking at least three months before the start of treatment, to improve the chances of pregnancy.  

  • Obesity

Obesity is associated with a lower success rate in women undergoing in vitro fertilization (IVF). Women with a very low body weight also likely to experience a lower success rate in IVF than women whose body weight falls in the normal range.

 In men, obesity is associated with low sperm count and motility. Weight loss also helps improve semen quality and erectile dysfunction. 

  • Exercise

Moderate exercise is associated with higher pregnancy rates in women. However, Vigorous exercise is not recommended. Similarly, exercise has beneficial effects in the case of men. One hour of exercise three times a week results in improved sperm count motility and normal sperm count. 

  • Caffeine Intake

Excessive caffeine intake is associated with a delay in time to conception. Consumption of even moderate amounts of caffeine (200-300 mg/day) is associated with lower pregnancy rate and a higher rate of miscarriage 

  • Alcohol Consumption

Extreme alcohol intake has been associated with decreased fertility four drinks per week are associated with decreased success rate in IVF.

Heavy alcohol consumption in men is associated with decreased sperm count, motility, and percent of normal-appearing sperm. Semen parameters have been shown to improve after three months of abstinence from alcohol. 

  • Recreational Drugs

Women who use marijuana appear to be likely to experience infertility. In men, marijuana has been found to increase ejaculation problems and impotence as well as reduce sperm count and motility. Most negative effects of recreational drugs have been shown to be reversed by discontinuing their use. 

In addition to all this:

 Some studies have shown tight undergarments in men show in increase scrotal temperature raising concern that it may impair sperm production. At present, there is no such evidence that tight clothing is associated with infertility in men. The same goes for hot baths or hot tubs.
