Vitamin E, particularly in the forms of beta and delta tocopherols, has been traditionally used to support reproductive health. Its association with fertility dates back to the early 20th century when it was first discovered in studies with rats, where deficiency led to infertility and fetal resorption. This led to Vitamin E sometimes being referred to as the "fertility vitamin" in older texts. The tocopherol family, named from the Greek words meaning "to bear offspring," further emphasizes this historical link.

However, most scientific studies have focused on alpha-tocopherol rather than beta and delta forms. While Vitamin E's antioxidant properties are well-established and may theoretically support reproductive tissues by protecting cells from oxidative damage, direct evidence in humans is limited, especially for the beta and delta tocopherols. Some small studies have explored Vitamin E supplementation in male infertility, with mixed results, and typically these have used the alpha form. There is little robust clinical evidence demonstrating that beta or delta tocopherols specifically benefit human reproductive health.

In summary, the use of Vitamin E (including beta and delta tocopherols) to support the reproductive system is rooted in traditional and historical observations, with some animal data, but lacks strong scientific validation in humans, particularly for these specific tocopherol forms.
