Can You Get Pregnant During Perimenopause?
By Dr (TCM) Attilio D'Alberto | Traditional Chinese Medicine Practitioner, Wokingham
Perimenopause — the transitional phase leading up to the final menstrual period — can span anywhere from two to twelve years and typically begins in the mid-to-late forties, though it can start earlier. During this time, the ovaries produce oestrogen and progesterone in increasingly erratic patterns, cycles become irregular, and ovarian reserve declines. Yet ovulation can and does still occur, which means pregnancy is still possible — and in some cases, unexpected. For women who are actively trying to conceive during perimenopause, understanding what is possible and how to optimise every cycle is essential.
Is Pregnancy Possible During Perimenopause?
Yes — as long as ovulation is still occurring, pregnancy remains possible. Perimenopause does not equate to infertility. Many women in their mid-to-late forties conceive naturally, and a significant number do so unexpectedly because they assume their fertility has ended. Contraception remains necessary for women who do not wish to conceive until periods have been absent for 12 consecutive months (the definition of menopause).
That said, the probability of natural conception per cycle is substantially lower during perimenopause than at younger ages. Egg quality declines with age, the rate of chromosomal abnormalities in embryos rises steeply, and the risk of miscarriage increases. For women actively trying to conceive during this phase, every cycle matters and optimising egg quality is the priority.
Challenges to Conception in Perimenopause
- Irregular ovulation — cycles may be anovulatory, making it harder to time intercourse or plan IVF stimulation
- Declining egg quality — mitochondrial function in the oocyte declines with age, increasing the proportion of chromosomally abnormal eggs
- Low AMH and high FSH — these markers reflect diminished ovarian reserve and are associated with reduced IVF response
- Thin uterine lining — lower oestrogen production can result in insufficient endometrial development for implantation
- Higher miscarriage risk — the majority of pregnancies lost in women over 43 are due to chromosomal abnormality in the embryo
How TCM Supports Fertility During Perimenopause
In my clinic, I regularly work with women in their forties who are trying to conceive — both naturally and alongside IVF. Traditional Chinese medicine has a coherent and clinically useful framework for understanding age-related fertility decline in terms of kidney jing depletion — the gradual diminishment of the fundamental essence that governs reproductive capacity. Treatment aims to nourish and support the remaining reserves as efficiently as possible, improving the quality of the eggs that are still being produced.
Acupuncture supports perimenopausal fertility by improving ovarian blood flow, supporting the hormonal axis, and regulating the increasingly erratic cycle that characterises this phase. Research has shown that acupuncture can improve ovarian response in poor responders, reduce FSH levels, and support endometrial development. For women going through IVF, acupuncture around the stimulation phase and embryo transfer improves outcomes — and this benefit is proportionally greater in women with a poorer prognosis.
Chinese Herbal Medicine for Perimenopausal Fertility
Chinese herbal medicine plays an important role in nourishing kidney yin and jing — the foundations of egg quality — and supporting the hormonal transitions of the cycle. Formulas that deeply nourish kidney yin and blood, such as modified versions of Zuo Gui Wan or Liu Wei Di Huang Wan, are among those I use most frequently for women trying to conceive in their forties. These are combined with qi and blood tonics and, where appropriate, gentle yang support to ensure the cycle has sufficient warmth and energy in the second half. Treatment typically runs for three months before a conception attempt or IVF cycle.
Supplements to Consider
CoQ10 (ubiquinol, 400–600mg daily) is strongly evidence-backed for improving mitochondrial function in ageing eggs and should be started at least three months before conception is attempted. DHEA (25–75mg daily) has a growing evidence base for improving ovarian response in poor responders and diminished ovarian reserve — though this should be discussed with a reproductive specialist before starting. A high-quality prenatal multivitamin, vitamin D, and omega-3 fatty acids complete the evidence-based foundation.
When to Consider Donor Eggs
For women over 45, or those whose AMH is very low and IVF cycles have failed repeatedly, donor egg IVF offers the highest success rates. This is a very personal decision and one I support patients in thinking through without pressure. Some women choose to pursue donor eggs; others strongly prefer to continue trying with their own. TCM treatment is relevant in both cases — for women continuing with their own eggs, it optimises quality; for those pursuing donor egg IVF, it supports endometrial receptivity and the implantation environment.
