The roots of the maca plant, or Lepidium meyenii, can be used by men for several purposes. Traditionally known as an aphrodisiac, the root may be helpful in increasing male libido and relieving sexual dysfunction. It is also thought to help improve the quantity and quality of semen and sperm that men produce, and might therefore contribute to improved fertility. The other main use of maca for men is to improve overall energy levels, which can in turn increase stamina and help to improve performance in sports and other physical activities.
One of the primary uses of maca for men is to help improve sexual function and desire. There is some evidence that the root may help increase and regulate sex hormone production, which in turn has positive effects on libido and the ability to get and maintain an erection. Some studies have shown that men who take maca have seen an increase in their desire for sexual activity.

Maca may be particularly useful for older men whose libido has decreased with age, though it can be effective for younger men as well. Those with erectile dysfunction may see improvement of their condition from taking a maca supplement. It can also help to relieve sexual dysfunction related to stress, depression, or the use of certain drugs like selective-serotonin reuptake inhibitors (SSRIs).

Another of the potential benefits of maca for men is an improvement in fertility. In addition to improving a man's desire and ability to have sex, it can also have positive effects on sperm production. Research has demonstrated that men taking maca can see an increase in the amount of semen they produce. They also tend to produce a higher volume of sperm, and the sperm they produce often has greater motility. For men struggling with fertility issues like low sperm count and motility, taking maca may increase their chances of achieving pregnancy with a partner.
The other main benefit of maca for men is its effect on energy and stamina. Some research has indicated that using maca can help reduce muscle fatigue, soreness, or damage related to use during physical activity. This can in turn allow for greater endurance while participating in sports. Taking maca is also thought to increase overall energy levels and combat fatigue. These two effects together may work to improve performance in athletics as well as other physical activities.
