Hormone Balance: Needle stimulation triggers the hypothalamic-pituitary-ovarian axis, potentially influencing the release of FSH, LH, and estrogen — hormones essential to ovulation and cycle regularity.

Improved Blood Flow: Studies suggest acupuncture increases uterine and ovarian blood flow, which may improve endometrial receptivity and egg quality — both critical for successful implantation.

​

Cycle Regulation: Can help regulate irregular menstrual cycles and support consistent ovulation.

​

Stress Reduction: Chronic stress elevates cortisol, which can suppress reproductive hormones. Acupuncture activates the parasympathetic nervous system, helping lower cortisol and anxiety.

​

Immune Modulation: Some research points to acupuncture's role in calming immune responses that may interfere with implantation, particularly in cases of unexplained infertility or recurrent loss.
