Introduction<\/span><\/h2>\n

Do you ever wonder why IVF works for some couples in the very first cycle, while others take longer despite doing everything \u201cright\u201d? That is because the IVF success rate depends on several factors such as age, AMH levels, pre-existing conditions like PCOS or thyroid and even lifestyle choices. For instance, the <\/span>IVF success rate in India<\/span><\/strong> currently ranges between <\/span>20% to 40% per cycle<\/span><\/a>. The best part of it all, despite the above, is that you can improve your chances of conceiving. So, read on to <\/span>find out<\/span> what affects IVF success <\/span><\/strong>and the powerful changes you can bring into your routine.\u00a0<\/span><\/p>\n

What is In Vitro Fertilization (IVF)?<\/span><\/h2>\n

In <\/span>Vitro Fertilization<\/span>, or IVF, is a medical process <\/span>performed<\/span> to assist couples who are having trouble having a child <\/span>of their own<\/span> naturally.<\/span> “In vitro” is defined as “outside the body,\u201d referring to the lab setting where the process happens. Globally, over <\/span>2.5 million IVF cycles<\/span><\/a> are performed each year, with around 500,000 babies born annually through this method.\u00a0<\/span><\/p>\n

In this process, a woman\u2019s eggs are collected from her ovaries and fertilized with sperm in a lab. Once fertilization occurs, one or more healthy embryos are placed back into the uterus with the hope of achieving a successful pregnancy. The process usually involves hormone injections that stimulate the production of the eggs, frequent monitoring and a minor procedure for <\/span>both<\/span> egg extraction and embryo transfer.<\/span><\/p>\n

What Factors Influence the IVF Success Rate?<\/span><\/h2>\n

Globally, the IVF success rate ranges from <\/span>30% to 40% per cycle<\/span><\/a> for women under 35. However, this success is not guaranteed and depends on various personal, biological and lifestyle-related factors. Let\u2019s explore what affects IVF success in detail.<\/span><\/p>\n

1. Age: The Most Critical Factor<\/span><\/h3>\n

Age plays the most defining role in determining the IVF success rate by age. Women are born with all the eggs they will ever have. As they age, <\/span>both<\/span> the quantity and quality of those eggs decline,\u00a0 especially after age 35. Older eggs are more likely to have chromosomal abnormalities, which reduces the chances of successful fertilization, implantation and a healthy pregnancy. The given table <\/span>summarises live-birth rates by age as collated by the <\/span>USA Facts<\/span><\/a>:\u00a0<\/span><\/p>\n\n\n\n\n\n\n\n\n
Age Group<\/b><\/td>\nIVF Success Rate (per cycle)<\/b><\/td>\nComment<\/b><\/td>\n<\/tr>\n
Under 35<\/span><\/td>\n40%\u201350%<\/span><\/td>\nHighest success due to better egg quality<\/span><\/td>\n<\/tr>\n
35\u201337<\/span><\/td>\n35%\u201340%<\/span><\/td>\nGood, but starts to decline<\/span><\/td>\n<\/tr>\n

41\u201342<\/span><\/td>\n10%\u201315%<\/span><\/td>\nSuccess lowers sharply<\/span><\/td>\n<\/tr>\n
Over 43<\/span><\/td>\n5% or less<\/span><\/td>\nVery low, often needs donor eggs<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The <\/span>IVF age limit<\/b> in India is generally capped at 50 years, though success can be seen even after it.<\/span><\/span><\/p>\n

2. Ovarian Reserve & Hormone Levels<\/span><\/h3>\n

A woman\u2019s ovarian reserve refers to the number of eggs left in her ovaries. One major marker is AMH (Anti-M\u00fcllerian Hormone). AMH is produced by small follicles in the ovaries that have the potential to grow and release an egg during ovulation. Here\u2019s how <\/span>average AMH levels by age<\/span><\/a><\/strong> correlate with fertility:<\/span><\/p>\n\n\n\n\n\n\n\n\n
Age<\/b><\/td>\nAverage AMH Level (ng\/mL)<\/b><\/td>\nOvarian Reserve<\/b><\/td>\n<\/tr>\n
<30<\/span><\/td>\n3.0\u20135.0<\/span><\/td>\nExcellent<\/span><\/td>\n<\/tr>\n
30\u201334<\/span><\/td>\n2.5\u20134.5<\/span><\/td>\nGood<\/span><\/td>\n<\/tr>\n
35\u201337<\/span><\/td>\n1.5\u20133.5<\/span><\/td>\nFair<\/span><\/td>\n<\/tr>\n
38\u201340<\/span><\/td>\n1.0\u20132.5<\/span><\/td>\nLow<\/span><\/td>\n<\/tr>\n
>40<\/span><\/td>\n<1.0<\/span><\/td>\nVery low<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

A person’s AMH may correspond well with their age, while in others, it may not. It\u2019s best to view your results with help from a doctor who can look at the full picture.<\/span><\/p>\n

3. Number of IVF Cycles<\/span><\/h3>\n

The IVF success rate in the first cycle is typically lower than the cumulative success rate over multiple attempts. Each cycle provides an opportunity for fertilization and implantation, and the body may respond more <\/span>favourably<\/span> in subsequent cycles with modified protocols. According to <\/span>Victorian<\/span> Assisted Reproductive Treatment Authority (VARTA)<\/span><\/a>, the average success of IVF based on the number of cycles is as follows:<\/span><\/p>\n
