Insights

The COVID-19 virus (SARS-CoV-2) negatively impacts male fertility by disrupting the HPG axis, affecting spermatogenesis and the epididymis. Vaccines are crucial for reducing infection rates and long-term risks.

Area of Science:

  • Reproductive Endocrinology
  • Virology
  • Public Health

Background:

  • The COVID-19 pandemic, caused by SARS-CoV-2, has had severe global health consequences, with higher complication and mortality rates observed in males.
  • The SARS-CoV-2 receptor's expression in the male reproductive tract and links between testosterone levels and viral infection highlight potential impacts on male fertility.

Purpose of the Study:

  • To review the effects of COVID-19 on the male reproductive system.
  • To investigate the impact of SARS-CoV-2 vaccines on male reproductive health.
  • To discuss mechanisms, asymptomatic infection effects, and long-term consequences of COVID-19 on male reproduction.

Main Methods:

  • A literature search was conducted using keywords: SARS-CoV-2, COVID-19, endocrine, spermatogenesis, epididymis, prostate, and vaccine.
  • Databases searched included PubMed, Web of Science, and Google Scholar.
  • The review covered peer-reviewed articles and reviews published between 2020 and 2022.

Main Results:

  • COVID-19 disrupts the hypothalamic-pituitary-gonadal (HPG) axis.
  • Negative impacts on spermatogenesis and epididymis function were observed.
  • The review explored mechanisms of viral impact and potential effects of SARS-CoV-2 vaccines on male reproductive health.

Conclusions:

  • COVID-19 negatively affects male reproductive health, specifically spermatogenesis and the epididymis, necessitating further research.
  • Vaccine development against SARS-CoV-2 variants is vital for reducing infection rates and mitigating long-term health risks.

Infertility in Males01:23

Infertility in Males

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...

Spermatogenesis01:41

Spermatogenesis

Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male...

Disorders of the Male Reproductive System

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....

Infertility in Females01:28

Infertility in Females

Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
Endometriosis, a condition characterized by abnormal growth of...

Sperm Transport01:15

Sperm Transport

The journey of sperm from its origin to the point of ejaculation begins within the seminiferous tubules of the testis. Here, Sertoli cells produce fluid that propels non-motile sperm through a series of conduits, starting with the straight tubules leading to the rete testis. This interconnected network of tubules acts as the initial pathway for sperm, guiding them into the efferent ductules and then into the epididymis for maturation.
The maturation phase occurs in the epididymis, where sperm...

The Y Chromosome Determines Maleness02:19

The Y Chromosome Determines Maleness

The Y chromosome is a sex chromosome found in several vertebrates and mammals, including humans. In addition to 22 pairs of autosomes, the human males have one X chromosome and one Y chromosome. In these organisms, the presence or absence of the Y chromosome determines the development of male traits.
Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size....
