    Vitex (Chasteberry) for Fertility Support Female

    Vitex can restore cycle regularity and lengthen short luteal phases via prolactin reduction, which may support conception in luteal phase defect — evidence is older and modest.

    Overview

    Vitex can restore cycle regularity and lengthen short luteal phases via prolactin reduction, which may support conception in luteal phase defect — evidence is older and modest.

    Verdict

    Mixed evidence

    Consider for irregular cycles or short luteal phase; not a general fertility booster.

    How It Works

    Dopaminergic action lowers elevated prolactin, supporting corpus luteum function and progesterone production needed for implantation.

    Evidence

    What the studies say

    Small trials (including a placebo-controlled study in women with luteal defect) showed improved progesterone and higher pregnancy rates; methodology predates modern standards. Best fit is irregular cycles with elevated prolactin.

    No studies are yet linked to both Vitex (Chasteberry) and Fertility Support Female.

    Safety

    Caveats

    Avoid with dopamine medications and hormonal contraception. Do not use to delay fertility workup in women 35+.

    Less likely to help if

    Regularly ovulating women; unexplained infertility needing medical evaluation.
