we gathered essential nutrients that were shown to improve the quantity and the qua­ lity of sperm cells and the composition of the seminal fluid:

• L-carnitine is a molecule that plays an es­ sential role in the production of energy in mitochondria, the “power plants” of sperm cells. L­-arnitine is therefore important for normal sperm cell motility.
• Coenzyme  Q10  is also required for proper function of the mitochondria, where it exerts a double function as antioxidant and as component of the respiratory chain that uses sugars to produce cellular energy.
• Taurine exerts positive effects on spermato­ genesis and confers to sperm some degree of protection against oxidative stress.
• Folic acid, Vitamin B12, Vitamin D3  and Zinc are needed to sustain cell division activity in order to continuously produce new sperm cells.
• Primary antioxidants like Vitamin C and Vi- tamin E have essential function in protecting cells from oxidative stress, which is one of the main factor affecting sperm quality.
• Zinc and Selenium are trace elements that contribute to normal fertility. Selenium is important to maintain structural integrity of the sperm cells.

Since spermatogenesis is a continuous process that generates sperm cells within 74 days, intake of during at least 3 months is necessary to obtain measurable improvements in sperm parameters. We recommend the use of Conceptive Men as long as required, until pregnancy.
