Healthy aging men experience gradual reproductive changes, with metabolic health, not testosterone, significantly impacting erectile function and hypogonadism symptoms. Maintaining glycemic control is key for reproductive health.
Area of Science:
- Reproductive endocrinology
- Aging male health
- Metabolic health and andrology
Background:
- Limited understanding of reproductive parameter changes in healthy aging men.
- Metabolic disorders are known to affect testosterone and erectile dysfunction (ED).
Purpose of the Study:
- Evaluate longitudinal changes in reproductive parameters in healthy aging men.
- Determine the influence of body mass index (BMI) and glycated hemoglobin (HbA1c) on these changes.
Main Methods:
- Longitudinal study of 197 healthy men (aged 18-84) with follow-up after 6 years.
- Comprehensive andrological examinations were performed.
- Analysis included assessment of testosterone, FSH, LH, SHBG, semen parameters, erectile function, andrology aging symptom (AMS) scores, BMI, and HbA1c.
Main Results:
- Testosterone levels declined significantly in men over 25.
- Erectile function progressively declined (p < 0.001).
- Higher HbA1c levels, not age or testosterone, were significantly associated with deteriorating erectile function and increased AMS scores in men over 45.
Conclusions:
- Healthy aging men experience gradual reproductive changes with preserved testosterone and semen parameters.
- Erectile function and hypogonadism-like symptoms are more strongly linked to glycemic control than testosterone levels.
- Preventive metabolic interventions are crucial for maintaining reproductive health in aging men.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
