Sexual desire in men: effects of oral ingestion of a product derived from fertilized eggs

J Int Med Res. 1997 Mar-Apr;25(2):62-70. doi: 10.1177/030006059702500202.


A commercial product, Libido (Libid, Libbido, Erosom and Ardorare, names used in different markets), which is based on components derived from fertilized, partly incubated chickens' eggs, has been used to treat diminished sexual desire in men. The results from two double-blind cross-over placebo-controlled experiments indicate that Libido has a significant enhancing effect on sexual desire in men with normal and reduced sexual drive. Over periods as short as 2 weeks, 58% of the participants with low sexual desire noticed improvement as assessed using a visual analogue scale. Data obtained from consumers suggest significant effects on the frequency of sexual intercourse, on increased self-esteem, on the level of happiness, and on stamina. In a separate Swedish study, 84% of 31 men reported increased sexual desire during 3 weeks on Libido. It takes 1-2 weeks of regular use of Libido (3 g twice daily) before noticeable changes are observed.
