Delaying Menopause: Is Frozen Ovarian Tissue the Answer?
New technique freezes ovarian tissue to postpone or even avoid menopause.
Menopause, the stage in a woman’s life when she has her last menstrual cycle, typically occurs around the age of 50. However, the years leading up to menopause, known as perimenopause, can be accompanied by bothersome symptoms such as hot flashes, night sweats, vaginal dryness, anxiety, and reduced sex drive. But what if there was a way to delay, or even prevent, menopause? 🌡️
A recent modeling study published in the American Journal of Obstetrics and Gynecology suggests that freezing and transplanting ovarian tissue could extend a woman’s fertile years well beyond the normal age of menopause. 😮 But before we get too excited, let’s dive into the details and consider both the benefits and potential drawbacks of this approach.
The Science Behind Ovarian Tissue Transplants
Ovarian tissue transplant, a technique already used to restore fertility following cancer treatments that harm the egg reserve in the ovaries, involves removing and cryopreserving (freezing) ovarian cortex tissue before undergoing cancer treatment. The tissue is then reimplanted after successful completion of the treatment. The ovarian cortex, which contains the majority of follicles responsible for egg maturation and ovulation, can be obtained from either a donor or the person undergoing the procedure. 🌱
Building upon previous studies, researchers at Yale School of Medicine created a mathematical model to predict the potential effects of ovarian transplant surgery on menopause delay in healthy women. They considered various factors, including age, amount of tissue harvested, single versus multiple transplants, and follicle survival rates post-transplantation.
How Effective is Ovarian Transplanting?
According to the mathematical model, ovarian tissue cryopreservation and transplant could significantly delay menopause for most women aged 40 and under. However, the success of the procedure depends on several factors:

- Age at tissue harvest: The younger the person, the greater the number and quality of eggs, increasing the likelihood of success.
- Amount of tissue harvested: Too little tissue might not delay menopause, while too much could bring it on earlier. The model provides optimal tissue quantities based on age.
- Single vs. multiple transplants: Dividing the tissue and transplanting it in several procedures can further extend the delay in menopause onset.
- Follicle survival rate: The higher the proportion of follicles that survive post-transplant, the longer menopause can be postponed.
For instance, the model highlights the case of a 25-year-old who had 25% of her ovarian cortex tissue harvested and transplanted in one procedure. If 40% of the follicles survived, menopause could potentially be delayed by almost 12 years. In contrast, if 80% of the follicles survived, the delay could be as long as 15.5 years. However, it’s important to note that the current success rate of ovarian transplant procedures is around 60% follicle loss, making the achievement of 80% follicle survival a future possibility.
Should Menopause be Delayed?
While the idea of delaying menopause may seem appealing to some, it’s essential to consider whether it’s truly beneficial and necessary. Menopause is a natural part of aging, not a medical condition. Many women embrace the end of menstruation, particularly those with menstrual disorders. For those who require support, hormone therapy has proven effective in managing menopausal symptoms. 💊
However, for those who experience troubling symptoms during perimenopause and menopause, which can last for several years, delaying these symptoms might positively impact their quality of life. Moreover, later menopause has been linked to a lower risk of osteoporosis, cardiovascular disease, and all-cause mortality. On the flip side, there is an increased risk of breast, endometrial, and ovarian cancers associated with delayed menopause.
As Dr. Robin Noble, Chief Medical Officer at Let’s Talk Menopause, suggests, hormone replacement therapy (HRT) can effectively alleviate menopausal symptoms without prolonging the length of menstrual cycles. MHT allows for individualized treatment options, considering the risks and benefits for each person.
Additionally, the decision to undergo surgery involving cryopreserved ovarian tissue should not be taken lightly. It requires repeated abdominal or laparoscopic procedures, necessitating careful consideration of the potential benefits and risks.
Q&A: Addressing Additional Concerns
Q: Does freezing ovarian tissue have any other potential benefits aside from delaying menopause?
A: Aside from potentially delaying menopause, freezing ovarian tissue has already been used to restore fertility in cancer patients undergoing treatment that may damage their egg reserve. It offers hope to those who wish to preserve their ability to have children in the future.
Q: Are there any risks or complications associated with ovarian tissue transplant surgery?
A: Ovarian transplant surgery carries risks inherent to any surgical procedure, such as infection, bleeding, and damage to surrounding organs. Additionally, long-term effects of the procedure on a person’s overall health and hormone levels are still being studied.
Q: Can cryopreserved ovarian tissue be used to treat other conditions aside from delaying menopause?
A: Currently, the primary use of cryopreserved ovarian tissue is for preserving fertility in cancer patients. However, ongoing research is exploring the potential application of this technique in treating conditions such as premature ovarian insufficiency (POI) and certain genetic disorders.
Conclusion
While the notion of freezing and transplanting ovarian tissue to delay menopause is intriguing, it’s vital to weigh the potential benefits against the risks and personal preferences. Menopause is a natural part of life, and hormone replacement therapy remains an effective option for managing symptoms. As we learn more about the field of menopause research, it’s essential that individuals have access to accurate and up-to-date information to make informed decisions about their health.
So, whether you choose to embrace the natural progression of menopause or explore alternative options, remember that knowledge is power. Stay informed, consult with healthcare professionals, and make the best decision for your own unique journey through life’s changes. 💪
