Introduction\nThe fertility journey is a long process. Understanding the process in detail is important, and it will help in making informed decisions. We will give the factors that decide the success rates of IVF at different ages. The information in this blog will help you whether you are searching or preparing to go for your first IVF cycle. \nIn vitro fertilisation (IVF)\n is a process of fertilisation in which an egg is combined with sperm outside the body in a petri dish. The process involves monitoring and stimulating the ovulatory process, then removing an ovum or ova (egg or eggs) from the ovaries and enabling sperm to fertilise them in a culture medium in a laboratory.\nAfter a fertilised egg undergoes embryo culture for 2–6 days, it is transferred by catheter into the uterus, with the intention of establishing a successful pregnancy.\nIVF Success Rates\nIVF success rates are the percentage of all IVF procedures that result in favourable outcomes. Depending on the type of calculation used, this outcome may represent the number of confirmed pregnancies, called the pregnancy rate, or the number of live births, called the live birth rate. Due to advances in reproductive technology, live birth rates of IVF have increased.\nThanks to advancements in technology and medical practices, IVF success rates have improved significantly. Factors such as enhanced egg retrieval, embryo culture, and transfer techniques have contributed to a higher chance of success. However, individual outcomes can still differ based on age, infertility cause, and overall health.\nThe success rate depends on various factors, including the woman's age, the cause of infertility, the embryo's status, reproductive history, and lifestyle. Younger candidates of IVF are more likely to get pregnant. People older than 41 are more likely to get pregnant with a donor egg. People who have been previously pregnant are, in many cases, more successful with IVF treatments than those who have never been pregnant.\nThe rate of successful pregnancy in younger patients is always slightly higher. At GarbhaGudi, success rates are upto 70% for those who are younger than 35 years of age who do not have any other serious health issues. Success rates for older patients are generally lower and decrease with age, with 37-year-olds at 40 to 50 %, and for those older than 48 are very low. \nIt is impossible to determine if superior technique or patient selection is responsible for the success rates. It is an expert evaluation of cases and an individualised treatment plan that is responsible for higher success rates.  Further, pregnancy rates can be increased by transferring embryos at the right time, after all required tests, to achieve a successful pregnancy. \nIVF attempts in multiple cycles result in increased cumulative live birth rates. Depending on the demographic group, one study reported 50% to 60% for three attempts, and 61% to 80% for six attempts.\nPredictors of success\nThe main potential factors that influence pregnancy rates in IVF have been suggested to be maternal age, duration of infertility or subfertility, and number of oocytes, all reflecting ovarian function.  Optimal age is 23–39 years at the time of treatment.\nFactors that affect the outcome of IVF include:\nAs maternal age increases, the likelihood of conception decreases, and the chance of miscarriage increases.\nWith increasing paternal age, especially 50 years and older, the rate of blastocyst formation decreases.\nTobacco smoking reduces the chances of IVF producing a live birth by 34% and increases the risk of an IVF pregnancy miscarrying by 30%.\nA BMI over 27 causes a 33% decrease in the likelihood of having a live birth after the first cycle of IVF, compared to those with a BMI between 20 and 27. \n Also, pregnant people who are obese have higher rates of miscarriage, gestational diabetes, hypertension, thromboembolism, and problems during delivery, as well as leading to an increased risk of fetal congenital abnormalities. \nAn ideal body mass index is 19–30, and many clinics restrict this BMI range as a criterion for initiation of the IVF process. \nSalpingectomy or laparoscopic tubal occlusion before IVF treatment increases the chances for people with hydrosalpinges.\nSuccess with previous pregnancy and/or live birth increases chances\n \nLow alcohol/caffeine intake increases the success rate.\nThe number of embryos transferred in the treatment cycle, and the embryo quality.\nSome studies also suggest that autoimmune disease may play a role in decreasing IVF success rates by interfering with the proper implantation of the embryo after transfer.\nWhat Really Improves Your Chances?\nPatients should follow the following to achieve optimal results:\nMaintain good health\nHealthy weight is a must\nAny underlying health conditions like diabetes, thyroid etc to be treated first and brought to normal levels\nAvoid smoking and excessive alcohol use\nEat a balanced and nutritious diet\nReduce stress\nDo regular exercise as suggested by the fertility specialist\nPractice yoga and meditation under the supervision of a specialist\nHave support from family and friends\nChoose a reputable clinic with success rates\nThe Importance of the Age Factor in Deciding IVF Success Rate\nThe age of the female partner is the most significant factor in treatment cycle success. Women’s age and utilizing their own eggs are significant IVF success elements to consider. While more young ladies have higher chances of IVF achievement, factors that diminish the odds of IVF achievement include being a more seasoned woman with fewer eggs and the lower quality of a more established woman’s eggs.\nHow can GarbhaGudi help you?\nWhether you’re planning to start a family, exploring fertility options, or considering assisted reproductive technologies like IVF, remember that every journey is unique.
