A significant drop in testosterone levels is linked (the causal relationship is in question; that is, it's not certain which came first, the chicken or the egg) to:
- Striking muscles: It's harder for you to gain muscle and you lose it faster than dignity at a karaoke.
- Beer belly: Fat accumulates, especially in places where it didn't before.
- Zombie mode activated: You lack energy, you feel slow, and concentrating is harder than assembling an IKEA furniture.
- Libido in "saving mode": Less desire, fewer erections...
- Soap opera mood: More irritability, anxiety, and unexplained sadness.
On the shady side of associations, there is also a relationship between testosterone and obesity, depression, petit suisse rates, reduction of immune system activity, or risk of cardiovascular diseases, among others (we don't want to scare you... it is what it is).
