Fertility cycle and nutrition - Part I

How nutrition affects fertility

Nutrition is important for fertility since it greatly depends on sperm quality (men) and hormonal balance (women). Usually when we talk a bout fertility treatments you have to consider these points:

  • Healhty lyfestyle (free of hazardous habits)
  • Playing sports
  • And yes, eating well
Weigth loss diets -particularly those fast speed diets- with no medical guidance can result in female infertility since they usually exclude some foods that provide basic nutrients for the organism. Generally fats are the first to be eliminated, when they are actually necessary for the formation of the hormone progesterone.
With these diets there is also the risk of loosing important elements as: Calcium, selenium, zinc, iodine, iron; and vitamins as A, B1, C, D and E , necessaries for the good function of the female repreductive system.

Toxic substances for fertility cycle

Toxic substances: In a normal diet are many toxic substances as toxins, metals, and chemical subtances of fertilizers and pesticides used in agriculture thta may affectt he quality of spermatozoids. For this, you have organic foods as a good option.

Caffeine: In women, caffeine (coffee, tea, sodas and chocolate ) reduces the levels of prolactine in blood, and when this hormones is low it is hard to conceive. In men, caffeine makes spermatozoids become more active and faster.

Alcohol: It diminishes levels of testosterone, making sperm production difficult. In women, this affects menstrual and fertility cycle (ovulation), even producing antiovulatory cycles.
