FertilAid is a fertility supplement with two formulas for men and women. FertilAid combines a blend of vitamins, minerals and herbs to enhance fertility and regulate the female menstrual cycle. The men’s formula is designed to increase sperm count and overall sperm health. FertilAid has been proven to effectively improve sperm motility and sperm count in an independent study performed by Dr. J.E. Ellington, a reproductive endocrinologist. No side effects have been reported for FertilAid for men or women. This supplement is made up of several herbs, however, which do have reported side effects.

Red Clover

Red clover is an ingredient in the FertilAid women’s formula. According to the University of Maryland Medical Center, the effects of red clover are similar to those of estrogen on the body, and it may help regulate the menstrual cycle. Red clover has been reported to cause side effects such as headache, skin rash and stomach discomfort, including nausea. No serious side effects related to ingesting red clover have been reported.


Chasteberry is an ingredient in the women’s formula; it is also known as vitex agnus-castus. It is an herb that has been used for centuries for regulating and balancing women’s menstrual cycles. This herb may cause several mild side effects including nausea, upset stomach, dizziness and a rash. Chasteberry may interact with some medications and birth control pills. You should contact a healthcare provider knowledgeable in herbal remedies prior to taking this supplement, especially if you are on medications or have underlying health conditions.


Carnitine, or L-carnitine, is an ingredient in the FertilAid men’s formula. It is included in the formula for sperm health, maturity and movement. The University of Maryland Medical Center notes that L-carnitine has been shown in several studies to increase sperm count. High doses above 5 g per day may cause diarrhea. L-carnitine may also cause an increase in appetite, skin rash and body odor. No serious side effects have been reported in men who take this supplement.

Asian Ginseng

Asian ginseng is also included in the men’s formula. Studies have shown that Asian ginseng has a positive effect on male fertility, including increasing sperm count and movement. Asian ginseng may cause a variety of side effects such as increased blood pressure, sleeplessness, anxiety, diarrhea, vomiting, headaches, feelings of euphoria and nosebleeds. Sleeplessness and nervousness may occur especially if the herb is taken concurrently with caffeinated beverages.
