Male gonadal axis function in patients with type 2 diabetes
Hormone Molecular Biology and Clinical Investigation
|April 13, 2016
Summary
Type 2 diabetes patients often have lower testosterone levels and hypogonadism. This review assesses how diabetes impacts the male reproductive system, exploring factors like insulin resistance and hyperglycemia.
Area of Science:
- Endocrinology
- Diabetology
- Reproductive Health
Background:
- Type 2 diabetes is linked to reduced serum testosterone and increased hypogonadism prevalence.
- Factors like age, obesity, insulin resistance, and hyperglycemia may contribute to lower testosterone in diabetic patients.
Purpose of the Study:
- To review the alterations in the male gonadal axis observed in patients with type 2 diabetes.
- To explore the potential mechanisms linking type 2 diabetes to decreased testosterone production.
Main Methods:
- Literature review of studies investigating testosterone levels and gonadal function in type 2 diabetes.
- Analysis of proposed mechanisms including insulin resistance, leptin resistance, aromatase activity, and hyperglycemia.
Main Results:
- Type 2 diabetes patients exhibit lower testosterone levels and higher hypogonadism rates compared to non-diabetic individuals.
- Insulin resistance, leptin resistance, and potentially hyperglycemia are implicated in reduced testosterone production.
- Aromatase activity in adipose tissue may increase estrogen levels, leading to central negative feedback.
Conclusions:
- Type 2 diabetes significantly affects the male gonadal axis, leading to hypogonadism.
- Multiple metabolic and hormonal factors associated with diabetes contribute to decreased testosterone levels.
- Further research is needed to fully elucidate the complex interplay between type 2 diabetes and male reproductive health.

Diabetes Mellitus: Type 2 and Gestational
5.4K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Carbohydrate Metabolism
14.9K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

The Endocrine System
1.9K
The endocrine system is an extensive network of glands – organs or tissues in the body that create chemicals that control many bodily functions, that secrete hormones, which are chemical messengers that play essential roles in regulating various bodily functions. These hormones are secreted into the bloodstream and travel throughout the body. They require specific receptors to convey signals to cells possessing these corresponding receptors. This complex signaling mechanism ensures that...

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Diabetes: Management and Pharmacotherapy
1.4K
The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.
