In vitro fertilization (IVF) is a widely utilized assisted reproductive technology (ART) that has helped countless couples and individuals. Concerns about whether in vitro fertilization (IVF) can cause early menopause stem from the hormonal stimulation involved in the procedure. Women who undergo IVF are given large dosages of medications to encourage multiple egg production from the ovaries. This process temporarily increases estrogen levels and can cause hormonal fluctuations.
Studies, however, show that neither menopause nor overall ovarian reserve is accelerated by this brief hormonal treatment. IVF does not result in early menopause since the eggs that are extracted during stimulation are the same ones that would naturally degenerate during that cycle, according to research published in the journals Fertility and Sterility and Human Reproduction.
The hormonal treatments used in IVF primarily recruit eggs that are already in the process of maturing, which would otherwise be lost in that menstrual cycle. Long-term studies, including those cited in the “Journal of Assisted Reproduction and Genetics,” have not found a significant difference in the age of menopause onset between women who have undergone IVF and those who have not. Therefore, while IVF involves substantial hormonal changes in the short term, there is no convincing evidence to suggest that it leads to early menopause or adversely affects long-term ovarian health.
Understanding Menopause
A woman’s reproductive years come to an end with menopause, a normal biological process that usually happens between the ages of 45 and 55. Her condition is formally diagnosed once a woman has missed her menstrual cycle for 12 consecutive months. The chemicals that control ovulation and menstruation, progesterone and estrogen, are gradually produced less by the ovaries during this transition. Common menopausal symptoms include hot flashes, nocturnal sweats, mood changes, and vaginal dryness. Women’s symptoms can differ significantly in nature and intensity.
Because of the drop in estrogen levels, menopause can also have long-term health repercussions. Osteoporosis is a disorder that weakens bones and increases their susceptibility to fractures; postmenopausal women are more likely to get it. Estrogen is also known to affect cardiovascular health since it regulates cholesterol and blood vessel elasticity. Hormone replacement therapy (HRT), lifestyle modifications, and other therapies can help control menopausal symptoms and lower health risks. To create a plan that best meets their needs, women should talk about these alternatives with their healthcare professionals.
Premature Menopause and Primary Ovarian Insufficiency (POI)
- Premature Menopause Occurs before the age of 40 and affects about 1% of women. It can result from genetic factors, autoimmune diseases, or medical treatments.
- Primary Ovarian Insufficiency (POI): A condition where the ovaries stop functioning correctly before age 40, often leading to premature menopause. Unlike natural menopause, POI can be intermittent, with occasional periods and the potential for pregnancy.

The IVF Process
The IVF process, or in vitro fertilization, is a multi-step procedure designed to assist individuals and couples with fertility challenges in achieving pregnancy. It begins with ovarian stimulation, where hormonal medications are administered to stimulate the ovaries to produce multiple eggs. This is followed by monitoring through ultrasounds and blood tests to track the development of the follicles containing the eggs. Once the follicles reach the desired size, a trigger shot is given to mature the eggs, and they are then retrieved through a minor surgical procedure known as transvaginal ultrasound aspiration.
After being retrieved, the eggs are fertilized in a laboratory setting using conventional insemination or intracytoplasmic sperm injection (ICSI), which is inserting a single sperm directly into an egg. For several days, the fertilized eggs—now embryos—are cultivated to track their growth. One or more of the embryos are chosen for transfer into the woman’s uterus once they reach an ideal stage, which is typically three to five days following fertilization. A tiny catheter put through the cervix is used to do this. Cryopreserve any high-quality embryos that are left over for later use. The last stage is to use blood tests and ultrasounds to check for signs of pregnancy and implantation.
- Ovarian Stimulation: Hormonal drugs cause the ovaries to become more active and produce more eggs.
- Egg Retrieval: A small surgical incision is made to remove mature eggs from the ovaries.
- Fertilization: In a lab setting, sperm are injected into the recovered eggs to commence fertilization.
- Embryo Transfer: In an attempt to conceive, the fertilized embryos are inserted into the uterus.
The Concern: Can IVF Cause Early Menopause?
The primary concern regarding IVF and early menopause stems from the ovarian stimulation phase, where high doses of hormones are used to stimulate the ovaries to produce multiple eggs. This process raises questions about whether it accelerates the depletion of a woman’s ovarian reserve (the total number of eggs she has).
Research and Expert Opinions
Studies on IVF and Menopause
- Long-term Studies: Several long-term studies have investigated whether IVF treatment is associated with earlier onset of menopause. A study published in Fertility and Sterility found no significant difference in the age of menopause onset between women who underwent IVF and those who did not.
- Comprehensive Reviews: A review in Human Reproduction Update concluded that there is no convincing evidence that ovarian stimulation for IVF accelerates ovarian aging or leads to premature menopause.
Expert Opinions
- Reproductive Endocrinologists: Most reproductive endocrinologists agree that IVF does not cause early menopause. They emphasize that ovarian stimulation mainly recruits eggs already on the path to degeneration.
- Hormonal Impact: While IVF treatments involve significant hormonal manipulation, these are short-term interventions and are not believed to have long-lasting effects on overall ovarian function.
Potential Mechanisms of IVF and Theories
Hormonal Fluctuations
- Temporary Hormonal Changes: The high hormone levels during IVF cycles can cause temporary changes in menstrual cycles and hormonal balance, but these effects are generally short-lived and do not lead to long-term ovarian damage.
Stress and Menstrual Irregularities
- Psychological and Physical Stress: The stress of undergoing IVF can temporarily disrupt menstrual cycles and cause irregular periods, but this is not equivalent to the onset of menopause.
Genetic and Environmental Factors
- Genetic Predisposition: Women with a family history of early menopause may be more sensitive to hormonal changes, but IVF itself is not a causative factor.
- Environmental Influences: Age at menopause onset is more influenced by lifestyle variables than by IVF therapy, including food, smoking, and general health.
Case Studies and Clinical Evidence Linking IVF and Menopause
Case Studies
- Individual Experiences: While some women report changes in their menstrual cycles post-IVF, these are typically temporary. Detailed case studies often show that other factors, such as age and pre-existing conditions, are more influential in these changes.
Clinical Trials
- Prospective Studies: Clinical trials monitoring women undergoing IVF over long periods have consistently shown no increased risk of premature menopause compared to the general population.
Registry Data
- National IVF Registries: Data from national IVF registries provide robust evidence that the average age of menopause in IVF-treated women is similar to that of the general population.

Considerations for Women Undergoing IVF
Although there has been no solid evidence linking IVF to the early onset of menopause, what are some considerations that women undergoing IVF should go through?
Consultation and Assessment
- Thorough Evaluation: Women considering IVF should undergo a comprehensive assessment of their ovarian reserve and overall reproductive health.
- Risk Factors: Discussing personal and family history of menopause with a healthcare provider can help identify any potential risk factors.
While it always pays to be well-informed about every step of your fertility journey. It is also paramount that you consult with professionals with vast experience in fertility care. Professionals like CarefulTrip agency have helped hundreds of patients from vastly varied backgrounds and medical histories receive successful fertility treatment at the excellent MOM fertility Clinic in Tehran. Sometimes, information alone isn’t enough, and CarefulTrip helps you access the past experiences of others who have gone through the same challenges you are going through.
Monitoring and Follow-Up
- Regular Monitoring: Regular monitoring of ovarian function during and after IVF treatment helps ensure any changes are promptly addressed.
- Post-Treatment Care: Post-treatment follow-up can help manage temporary menstrual irregularities or hormonal imbalances.
Lifestyle and Health
- Healthy Lifestyle: Overall reproductive health can be supported by leading a healthy lifestyle that includes eating a balanced diet, getting regular exercise, and quitting smoking.
- Stress Management: Managing stress through counseling, support groups, and relaxation techniques can mitigate the psychological impact of IVF.
Final Words
Current research and expert opinions strongly indicate that IVF does not cause early menopause. The ovarian stimulation process, a crucial component of IVF, does not deplete the ovarian reserve in a way that would accelerate menopause. While temporary hormonal changes and menstrual irregularities may occur, these are short-term effects and do not have lasting impacts on ovarian function.
It is important to inform women who are thinking about IVF that there is no chance of early menopause associated with the process. Individual risk factors, including lifestyle decisions and genetic predisposition, have a more significant influence on when menopause begins—managing reproductive health before, during, and after IVF treatment requires speaking with medical professionals, going through extensive evaluations, and leading a healthy lifestyle.
Since the nature of IVF treatment lends it to be a private matter, often not spoken about in public or within the family even; a practice that should be abolished altogether. Therefore, questions like ‘Can IVF cause early menopause?’ are bound to pop up because there is misinformation aplenty about the whole process. However, consulting with professionals in the fertility field, like the CarefulTrip agency, will help alleviate such concerns. CarefulTrip not only offers a free consultation to those seeking answers to these questions but also helps find a curated fertility path for every patient based on their individual needs, as well as offering their services for some of the most affordable prices in the world.
