Researchers haven't unraveled the mystery of just how testosterone increases libido. It's normal for a man's sex drive to slowly decline from its peak in his teens and 20s, but libido varies widely between men. What one man might consider a low sex drive, another might not. Also, sex drive changes within each man over time and is affected by stress, sleep , and opportunities for sex. For these reasons, defining a "normal" sex drive is next to impossible. Usually, the man himself identifies a lack of sex drive as a problem. Other times, his partner may consider it to be an issue.
The concentrations of serum total and free testosterone were studied in 30 healthy, middle-aged men during a dietary intervention program. When men were transferred from their customary diet to an experimental diet, which contained less fat with a higher polyunsaturated/saturated ratio (P/S-ratio) and more fibre, there was a significant decrease in serum total testosterone concentrations ( +/- vs +/- nmol/l SEM, P less than ). Furthermore, serum free, unbound testosterone fell from +/- to +/- nmol/l SEM (P less than ). The hormonal changes were reversible. This observation suggests that testosterone activity in plasma can at least partly be modified by changing the composition of the diet.
I’m 25 and I haven’t had my menstrual cycle in about 4 months. So I went to my doctor yesterday who did some labs and the only abnormality was my testosterone level which was low at a 28. I had no idea. I’ve been experiencing extreme fatigue, difficulty with weight loss, depression and no libido. Knock on wood I don’t also get the hair loss.
My doctor didn’t really say anything about it other then giving me a pill to try for 7 days to see if I get my menstrual cycle.
Should I be worried? What should I do?
Someone mentioned protein, does that help?
