Impaired sexual activity can affect quality of life and thus cannot be ignored. In the USA, the Massachusetts Male Aging Study showed that 52% of men aged 50–70 experienced some some degree of erectile dysfunction (ED). On a wider age range of 18–59, 10.4% of men mentioned an inability to achieve and maintain an erection in the National Health and The National Health and Social Life Survey ( ... The NHSLS used an area probability sample of 3,432 respondents. ...In the UK, similar figures were given in the National Survey of Sexual Attitudes and Lifestyles II, 2000–2001 (NATSAL II).

Other names: Lepidium meyenii, Peruvian ginseng
Maca is a plant with a radish-like root that is used as a food and for medicinal purposes.
Although maca is unrelated to the ginseng family, it has been dubbed "Peruvian ginseng" because it is used as a folk remedy to increase stamina, energy, and sexual function.
According to folklore, ancient Incan warriors took maca before going off to battle to make them physically strong. However, they were later prohibited from taking it, in order to protect conquered women from their heightened libidos. One study looked at the effect of 4 months treatment with maca tablets on semen quality in nine adult men. Treatment with maca resulted in increased seminal volume, sperm count, and sperm motility.
A 12-week randomized controlled trial looked at 1,500 mg maca, 3,000 mg maca, or placebo. After 8 weeks, there was an improvement in sexual desire in the men taking maca. Maca does not appear to affect hormone levels. Serum testosterone and estradiol levels were not different in men treated with maca compared to those who took the placebo. Other studies have found no effect on luteinizing hormone, follicle-stimulating hormone, prolactin, and 17-alpha hydroxyprogesterone.
Safety
No side effects or hazards have been reported and are unknown.
Drug Interactions

Maca is a root vegetable that is also used as a dietary supplement. As with many dietary supplements, maca is claimed to be beneficial for a wide variety of uses. Some of the claimed benefits of maca include treating the following conditions:
- Anemia
- Chronic fatigue syndrome
- Menstrual irregularity
- Menopause symptoms
- Osteoporosis
- Depression
- Stomach cancer
- Leukemia
- HIV and AIDS
- Tuberculosis
- Enlarged prostate (benign prostatic hyperplasia, or BPH)
- Impotence (also known as erectile dysfunction, or ED).
Maca is also used to enhance fertility, increase sexual desire, and improve stamina, athletic performance, and memory. Maca is also claimed to help stimulate the immune system.
There is little evidence to suggest that maca really works for most of these uses (see Does Maca Work?).
As a plant, maca contains many different compounds and nutrients. It contains carbohydrates, proteins, fiber, and fatty acids. It contains a few different plant sterols and polyunsaturated fatty acids, which may be responsible for many of the medicinal properties. It also contains a significant amount of minerals, such as calcium, iron, and copper. Maca also contains compounds known as glucosinolates, which may have anti-cancer properties.
It is not clear how exactly maca works for any use, although it has been shown that maca does not seem to affect testosterone, estrogen, or other similar hormones, at least in healthy men.
We all hear rumors about various natural sex products like maca. But using these Peruvian root supplements myself, I personally experienced a significant improvement in erectile tissue response. I call it "nature's answer to Viagra". Said Garry P. Gordon, MD, former president of the American College for Advancement in Medicine.
