Experts from Southwestern University claim that cold coffee increases libido in both men and women. The researchers conducted a series of studies to determine how this beverage stimulates sexual arousal.
In the first experiment, scientists recruited 240 men aged 26 to 47. Some of them had low libido. By regularly drinking 150 ml of cold coffee at lunch, 67% of the 120 men later admitted that their erectile dysfunction had significantly decreased, and 13% of respondents reported that their sexual performance had increased from one or two minutes to ten.
After drinking coffee during the day, women felt the approach of orgasm much faster in the evening than before.
Israeli sexologist Baruch Yeshin continued the research conducted by American scientists. He decided to find out which coffee was most beneficial for libido during hot weather. He recruited 64 patients and regularly administered different types of coffee during the day, morning, and evening. Here's what he discovered:
1. Coffee brewed in a Turk has the greatest effect on the human body.
2. The drink should be brewed in the evening, before bed. Strain it and pour it into an airtight container, leaving it in the refrigerator overnight.
3. To increase libido in the morning, a man needs to drink at least 150 ml of cold coffee, women – from 100 to 150 ml.
Scientists say the best time for summer sex is between 7:30 and 8:00 a.m.
