Acupuncture helps fertility and increases Live birth rate by 30%.

Acupuncture potentially affect fertility in a few ways suggested by research. 

First, acupuncture can induce vasodilation and blood flow to the uterus and ovaries, which are vital to reproduction. By inhibiting central sympathetic nerve tone.

Acupuncture also makes the body produce endorphins relieving the stress response associated with infertility and infertility-related treatment.

Acupuncture balances hormones. The release of neurotransmitters—such as dopamine, serotonin, neuropeptides, and oxytocin initiated by acupuncture could influence the hypothalamus–pituitary–ovarian axis to promote ovulation, regulate menstrual cycles, and increase overall fertility.

Acupuncture could affect glucose uptake in the skeletal tissue, decrease hyperinsulinemia, and might increase insulin clearance in polycystic ovary syndrome.

Recent data-analyses found that Acupuncture has been effective for increasing clinical pregnancy rates by 28%–32%, Ongoing pregnancy rate by 42%, and Live birth rate by 30%, compared to no treatment. Acupuncture does not increase the risk of miscarriage. Some analysis has shown that acupuncture reduced the miscarriage rate by 43%. Additionally, acupuncture was 42% more effective to increase live births when women had previously failed a cycle, and baseline pregnancy rate continues to mediate acupuncture's effects.
