Menopause is the moment when you’ve gone 12 consecutive months without a period, and perimenopause is the transitional stage leading up to that moment. Fertility doesn't stop overnight. Perimenopause is a gradual process that can span several years, and pregnancy is still possible even as it becomes less likely.
You may have heard stories of "menopause babies” — i.e. children from pregnancies during late perimenopause. These surprise pregnancies are rare, but they do happen. Ovulation can still occur irregularly during this stage. And for those who have reached menopause, assisted reproductive technologies like IVF have expanded the possibilities for family building.
Understanding your fertility during this transitional stage empowers you to make informed decisions. In this article we'll cover:
- The difference between perimenopause and menopause fertility
- Why pregnancy can still happen during perimenopause
- What "menopause babies" really means in the context of perimenopause and menopause
- How IVF works during and after this transition
- Health considerations for pregnancy after 40
Understanding perimenopause vs. menopause
Perimenopause is the transitional stage leading up to menopause, typically lasting 4 to 10 years. During this time, your hormone levels fluctuate unpredictably, causing irregular ovulation and menstrual changes. On average, perimenopause begins in your 40s, though some people experience it earlier or later.
Menopause is officially reached after 12 consecutive months without a period, marking the end of menstruation and natural fertility. The average age of menopause is 51, but this can vary based on genetics, lifestyle, and medical history.
During perimenopause, your ovaries still release eggs — just irregularly. Your ovarian reserve (the quantity and quality of remaining eggs) gradually declines, and FSH (follicle-stimulating hormone) levels rise as your body works harder to stimulate egg maturation. After menopause, natural ovulation stops entirely. This fertility decline happens progressively. Your fertility window shrinks during perimenopause but doesn't close completely until menopause arrives.
Can you get pregnant during perimenopause?
Yes, pregnancy is possible during perimenopause, although the likelihood decreases as you progress through this stage. Your ovaries still release eggs occasionally, even during irregular cycles. You might skip ovulation for months, then suddenly release an egg. Don't assume irregular periods mean you can't get pregnant.
According to the American Society for Reproductive Medicine, people in their early 40s have roughly a 5% chance of getting pregnant each month, compared to about 20% for those in their 30s. For folks in their late 40s, getting pregnant without medical assistance becomes increasingly rare but not impossible.
Keep in mind that these numbers are generalizations. Although fertility declines with age, the exact timeline varies significantly from person to person. Age alone doesn't equal infertility. Some people maintain relatively strong fertility into their mid-40s, while others experience earlier decline. If you're sexually active and don't want to get pregnant, be sure to continue using contraception throughout perimenopause.
Can you get pregnant during menopause?
Once you've reached menopause — confirmed by 12 months without a period — getting pregnant without medical assistance is no longer possible. Your ovaries have depleted their egg supply and no longer ovulate. However, your uterus can remain viable for pregnancy longer than your ovaries remain capable of producing eggs.
Pregnancy after menopause is still achievable through IVF using donor eggs or previously frozen embryos. The process involves hormone therapy with estrogen and progesterone to prepare your uterine lining for embryo implantation. This mimics the natural hormonal environment of pregnancy and helps the uterus remain receptive. With proper medical support, postmenopausal pregnancy success rates depend primarily on the age of the eggs used (whether from a donor or your own frozen eggs from earlier years) rather than your current age.
What is a "menopause baby"?
A menopause baby is a child born from pregnancy during late perimenopause, or a child born via IVF after menopause has been reached.
Unexpected perimenopausal pregnancies happen because ovulation becomes so irregular that it's difficult to track. You might assume you're no longer fertile due to several months without a period, only to ovulate unexpectedly. This unpredictability is why contraception remains important until you've officially reached menopause.
For postmenopausal pregnancies via IVF, the term "menopause baby" acknowledges the unique journey of pursuing parenthood after your body's natural fertility window has closed. These pregnancies require careful medical support and planning.
Later-in-life parenthood brings both opportunities and considerations. Many people feel more emotionally and financially prepared for parenting in their 40s and 50s. Others appreciate the maturity and life experience they bring to raising children. At the same time, physical demands of pregnancy increase with age, and parents must consider their long-term health and energy for active parenting years.
Everyone's path to parenthood looks different, and there's no single "right time" that works for everyone.
How IVF works during perimenopause or after menopause
During perimenopause, in vitro fertilization (IVF) can use your own eggs, but success rates decline as egg quality decreases with age. According to data from the Society for Assisted Reproductive Technology, success rates for live births using your own eggs range from about 20% for people ages 38 to 40, to less than 3% for people over the age of 42. Your fertility specialist will likely test your ovarian reserve through bloodwork and ultrasound to assess your remaining follicles.
IVF after menopause requires either donor eggs from a younger person or embryos created from eggs you froze earlier in life. The general success rate for IVF with genetically healthy embryos from women under 35 is about 51%. This rate correlates with the age of the egg used rather than your current age. Your care team will prescribe hormone therapy protocols to create the same hormonal environment your body would if your ovaries were still functioning, such as estrogen to thicken your uterine lining.
The bottom line: IVF during perimenopause with your own eggs becomes increasingly challenging as you age, while IVF with donor eggs or previously frozen eggs offers better success rates because they reflect the age when the eggs were created. Your care provider can help you understand which approach makes sense for your specific situation.
Emotional and health considerations
Pregnancy after 40 — whether during perimenopause or after menopause via IVF — requires careful consideration of both physical and emotional factors.
Health risks increase with maternal age, though many people have healthy pregnancies and deliveries in their 40s and beyond. More and more people are choosing to have babies after 40. For example, in the U.S. the fertility rate for people ages 40 to 44 has increased 127% since 1990.
Before attempting pregnancy during this stage, be sure to check in with your care provider for pre-pregnancy counseling. They can help you conduct comprehensive health screenings (like cardiovascular assessments) and manage any existing health conditions before pregnancy to improve outcomes. Higher-risk factors for pregnancy as you age include:
- Miscarriage and stillbirth rates increase
- Chromosomal abnormalities that cause developmental delays or intellectual disabilities become more common as egg quality declines
- Gestational diabetes, preeclampsia, or other complications occur more frequently
- Preterm labor and cesarean delivery rates are higher
Emotional readiness matters just as much as physical preparation. Later-in-life parenthood can feel isolating if most of your peers have older children or have completed their families. At the same time, many people report feeling more confident and prepared for the challenges of parenting with additional life experience.
Here are some considerations to guide you as you make the decision that feels right for you:
- Do you have a support network of family, friends, or community to help you through pregnancy and parenthood?
- Are you financially stable enough to handle the costs of fertility treatment, pregnancy care, and raising a child?
- Do you feel you'll have the long-term energy and health to stay actively involved in your child's life as they grow?
- Are you emotionally prepared for the medical interventions and monitoring that may be required?
Fertility support and next steps
If you're hoping to get pregnant during perimenopause or are considering IVF after menopause, taking action early maximizes your options.
See a fertility specialist if:
- You're under 35 and aren’t pregnant after 12 months of trying
- You're 35 to 40 and aren’t pregnant after 6 months of trying
- You're over 40 and want to get pregnant (schedule a consultation before trying)
- You're experiencing perimenopausal symptoms and want to understand your fertility status
Your specialist will conduct fertility testing to assess your ovarian reserve, evaluate your partner's sperm quality if applicable, and discuss treatment options based on your specific situation.
Fertility preservation is worth considering if you're in perimenopause but not ready to get pregnant immediately. Freezing eggs or embryos now — while you still have some ovarian reserve — preserves options for later. This can be especially valuable if you're unsure about your timeline for family building.

FAQ
What is a menopause baby?
A menopause baby is a child born via pregnancy during late perimenopause — a time when pregnancy seems unlikely due to irregular periods — or a child born via IVF after menopause using donor eggs or previously frozen embryos. The term acknowledges the unexpected nature of pregnancy during this reproductive transition or the medical treatment required to achieve pregnancy after natural fertility has ended.
Can you get pregnant at 50?
Yes, it is possible, but keep in mind that pregnancy at 50 without medical support is extremely rare, as most people reach menopause between 45 and 55. However, pregnancy at 50 is possible through IVF using donor eggs or embryos created from eggs frozen earlier in life. With appropriate medical treatment and hormone therapy, the uterus can support pregnancy after menopause. Success depends on comprehensive health screening and careful management of age-related pregnancy risks.
What are the risks of getting pregnant during perimenopause?
Pregnancy during perimenopause carries increased risks compared to pregnancy in your 20s and 30s. These include higher miscarriage rates, increased likelihood of chromosomal abnormalities like developmental delays greater risk of gestational diabetes and preeclampsia, and higher rates of preterm birth and cesarean delivery. Pre-pregnancy health evaluations and close medical monitoring throughout pregnancy help manage these risks effectively.
Can you have a healthy baby after menopause?
Yes, healthy pregnancy after menopause is possible through IVF with donor eggs or previously frozen embryos. While age-related risks exist, many people successfully carry healthy pregnancies and deliver healthy babies after menopause with appropriate medical support. Working with a fertility specialist and a high-risk obstetric care provider ensures the best possible outcomes.
