Vitamin B6 (pyridoxine and related compounds) has a scientifically supported role in the reproductive system, particularly in relation to hormone regulation and reproductive health. Vitamin B6 is involved in the synthesis of neurotransmitters and steroid hormones, including those critical for reproductive function such as estrogen and progesterone. Clinical studies have shown that vitamin B6 supplementation may be beneficial in alleviating symptoms of premenstrual syndrome (PMS), such as mood changes, irritability, and bloating. For example, a Cochrane review (2009) found moderate evidence that vitamin B6 can reduce the overall symptoms of PMS, although the quality of trials was variable.

Vitamin B6 is also used in the management of nausea and vomiting in pregnancy (NVP), commonly known as morning sickness. The American College of Obstetricians and Gynecologists recommends vitamin B6 as a first-line therapy for mild to moderate cases of NVP, based on multiple randomized controlled trials demonstrating its efficacy and safety.

While vitamin B6 is not a fertility treatment per se, its role in supporting hormonal balance and mitigating specific reproductive-related symptoms is well documented. However, evidence for its use beyond PMS and NVP, such as general fertility enhancement or broader reproductive health claims, is limited. Thus, while vitamin B6 has important and validated roles within specific aspects of reproductive health, its overall impact on the reproductive system is moderate.
