Summary
COVID-19 significantly impacts male testosterone levels, causing hypogonadism in 87% of patients. Hormone levels improved significantly after treatment, resolving hypogonadism in 40%, especially in younger individuals.
Area of Science:
- Endocrinology
- Virology
- Men's Health
Background:
- COVID-19 negatively affects the male reproductive system.
- Androgenic status in men with COVID-19 requires investigation.
Purpose of the Study:
- To evaluate total testosterone, sex hormone-binding globulin (SHBG), and free testosterone levels in men during acute COVID-19 and convalescence.
Main Methods:
- Prospective study of 70 men with moderate to severe COVID-19.
- Measured total testosterone and SHBG, calculated free testosterone.
- Data collected at hospitalization and discharge.
Main Results:
- 87% of patients presented with hypogonadism upon hospitalization.
- Inpatient treatment significantly increased total testosterone, SHBG, and free testosterone (p<0.001).
- Hypogonadism resolved in 40% of patients post-treatment.
Conclusions:
- COVID-19 adversely affects testosterone production, causing reversible hypogonadism.
- Younger patients demonstrate better reversibility of COVID-19-induced hypogonadism.

Disorders of the Male Reproductive System
538
Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra....

Testosterone: Functions and Regulation
949
The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...

Menopause
235
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

Infertility in Males
322
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...

Signs of Puberty
577
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Adrenal Gland Disorders
1.7K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...
