Asparagus racemosus, commonly known as Shatavari, has a long history of use in Ayurvedic medicine as a tonic for reproductive health, including for men. Traditionally, it is believed to enhance vitality, libido, and overall reproductive function. Ayurvedic texts describe Shatavari as a "rasayana" herb, meaning it is rejuvenative, and it is thought to balance the body's energies and support semen quality and quantity.

However, while there are some preclinical studies suggesting antioxidant and adaptogenic effects of Asparagus racemosus, direct scientific evidence in humans supporting its efficacy for the male reproductive system is limited. Animal studies have shown possible improvements in sperm count and motility, but robust clinical trials in men are lacking. Reviews of the available literature note the traditional use but emphasize the need for more high-quality research.

In summary, the primary justification for using Asparagus racemosus to support the male reproductive system comes from traditional use in Ayurvedic medicine, with only preliminary scientific exploration to date. The overall strength of evidence is low, with tradition outweighing direct scientific validation.
