A recent publication in New Scientist revealed the results of the studies by Italian scientists who found that an excessively high level of cholesterol or hyperlipidemia causes female sexual dysfunction.
It is a well-known fact that hyperlipidemia is the cause of atherosclerosis when plaque (or fat deposits) builds up inside the blood vessels. Plaque narrows the arteries and consequently, heart diseases and ischemia may occur. Now erectile dysfunction in men and frigidity in women may be added to this list of diseases.
It was found out that female sexual arousal directly depends on the genital blood flow. A group of scientists from the Second University of Naples studied female libido by the following criteria:
- level of sexual desire;
- frequency of orgasms;
- vaginal lubrication;
- satisfaction from sex.
Women participating in clinical studies were near menopause. Half of all women had hyperlipidemia.
It was found out that patients with hyperlipidemia were more likely to develop sexual dysfunction. 32% of women suffered female sexual dysfunction (FSD) or more commonly, frigidity. In a group of women with normal lipid level, this figure was no more than 9%.
Interestingly, but sexual desire does not depend on the level of fat in the blood.
Based on the results of the studies, a hypothesis was proposed that statins, medications reducing cholesterol biosynthesis in the liver, may improve sexual function of women who have hyperlipidemia. This hypothesis has not been clinically proved yet and it still needs to be confirmed.
