Are you a mouse?

The decline of circulating testosterone levels in aging men is associated with adverse health effects. During studies of probiotic bacteria and obesity, we discovered that male mice routinely consuming purified lactic acid bacteria originally isolated from human milk had larger testicles and increased serum testosterone levels compared to their age-matched controls.

I deal with mild colitis. During a flare, thankfully I've no had one for some time, libido tanks. The gut is a remarkable barometer when it comes to general health. I'm not surprised you respond as you do.
 
Gut microbiota linked to HPA axis hormones
Comparing the lowest and highest tertiles for hormones, researchers found positive associations for oxytocin with Dialister (P = .039) and Prevotella bacteria (P = .052) and negative associations for insulin-like growth factor I with Bifidobacterium (P = .018) and Parabacteroides distasonis (P = .042). Cortisol was positively associated with Catenibacterium (P = .003), Prevotella stercorea (P = .027) and P. copri (P = .058) and negatively associated with Bacteroides (P = .021).

Bifidobacterium was negatively associated with diabetes and substance use (P < .001), and that relationship remained significant after adjustment.

All associated bacteria except one produce gamma-amino butyric acid, a neurotransmitter important in the pathophysiology of type 2 diabetes and psychiatric disorders, the researchers noted, suggesting that certain gut microbes may serve as probiotic or psychobiotic therapies for these disorders.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
