Infertility in Males

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...

Sexually Transmitted Infections

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Giardiasis

Giardiasis

Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...

Amebiasis

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...

Candidiasis

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...

Trichomoniasis

Trichomoniasis

Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.

Amoebiasis in homosexual men.

A McMillan, H M Gilmour, G McNeillage

|April 1, 1984

Summary

Homosexual men infected with Entamoeba histolytica experienced longer gastrointestinal symptom durations and rectal mucosa abnormalities compared to uninfected individuals. No serum antibodies were detected in infected patients.

Area of Science:

Medical Parasitology
Gastroenterology
Infectious Diseases

Background:

Entamoeba histolytica is a significant cause of parasitic infections.
Understanding the clinical manifestations in specific populations is crucial for diagnosis and treatment.

Purpose of the Study:

To investigate the clinical, histopathological, and serological features of Entamoeba histolytica infection in homosexual men.
To compare these features with a control group of non-infected homosexual men.

Main Methods:

A comparative study involving 35 homosexual men infected with Entamoeba histolytica and 35 non-infected controls.
Clinical symptom assessment, histopathological examination of rectal mucosa, and serological testing for antibodies against E. histolytica.

Main Results:

No significant difference in the prevalence of gastrointestinal symptoms between infected and control groups.
A significantly longer mean duration of symptoms was observed in the amoebiasis group (p < 0.05).
Rectal mucosa histology was abnormal in 63.0% of infected men versus 7.4% of controls (p < 0.001).
Serum antibodies reactive to E. histolytica were not detected in any patient.

Conclusions:

Entamoeba histolytica infection in homosexual men is associated with prolonged gastrointestinal symptoms and rectal mucosal abnormalities.
Histopathological findings are more sensitive indicators than serological tests in this cohort.
Further research into the host-parasite relationship and diagnostic strategies is warranted.
