Association of testicular histopathology with sperm retrieval success rates in men with idiopathic non-obstructive azoospermia.

Introduction: Infertility is a major public health issue, with male factors alone contributing to 20-30% of cases. Non-obstructive azoospermia (NOA) is the most severe form, and although techniques like microdissection testicular sperm extraction (mTESE) offer hope, it remains challenging due to its uncertain causes. This study investigates the correlation between testicular histopathology and clinical parameters to enhance sperm retrieval (SR) prediction.

Perceived intravaginal ejaculation latency time: The diagnosis of premature ejaculation among Vietnamese men.

Introduction: Premature ejaculation (PE) is a prevalent sexual dysfunction in men that greatly affects their quality of life. In PE, the duration of sexual performance is considered an important aspect. However, a self-estimated value of intravaginal ejaculation latency time (perceived IELT, PIELT) as a criterion for diagnosis has not been specified.

Testosterone and aging male, a perspective from a developing country.

Purpose: Hypogonadism is associated with a wide range of physical and psychological symptoms that can affect the overall health of men. However, in a developing country, there are several imposing challenges in the diagnosis and treatment of hypogonadism, including a lack of awareness and understanding of the condition among healthcare providers and patients, limited resources and the high cost of treatment. This review aimed to examine the potential benefits and risks of testosterone replacement therapy (TRT) and provides a perspective of a developing country on the topic.

Investigating the microbial pathogens of sexually transmitted infections among heterosexual Vietnamese men with symptomatic urethritis.

Objective: To explore the microbial etiology of urethritis in Vietnamese men and the association with patients' characteristics, especially their sexual behaviors.

Methods: This study was conducted on 349 men who presented with symptomatic urethritis and evidence of STIs (determined by multiplex PCR tests) at the Department of Andrology and Sexual Medicine-Hanoi Medical University Hospital. All information regarding medical history, sexual activities, and symptoms of urethritis was documented.

Ultrasonic testicular size of 24,440 adult Vietnamese men and the correlation with age and hormonal profiles.

Testicular size is an important parameter to investigate male reproductive and sexual functions. However, diagnosis and treatments are hindered by the lack of country-specific standard values for testicular volume. We conducted the present retrospective chart review study on 24,440 men who sought consultation at Andrology and Sexual Medicine-Hanoi Medical University Hospital to provide a reference range of testicular volume and to determine the correlations between testicular volume, age and hormonal profiles.

The Sexual Long COVID (SLC): Erectile Dysfunction as a Biomarker of Systemic Complications for COVID-19 Long Haulers.

Introduction: Long term complications of COVID-19, the disease caused by the SARS-CoV-2, involve many organ systems, dramatically worsening the quality of life, and finally contributing to impaired physical functioning. Despite the presence of well-identified pathogenetic mechanisms, the effect of "Long COVID" on sexual health has been only marginally addressed.

Objectives: To provide coverage of the current literature on long COVID, its epidemiology, pathophysiology, and relevance for erectile function.

Data from 14,597 penile measurements of vietnamese men.

Background: Penis size is a highly sensitive topic, which has often raised concerns associated with human masculinity and male sexual health. Although data regarding penile dimensions have been published worldwide, little is known about these measurements in South-East Asian countries.

Objective: This study aimed to provide the reference range in penile length, circumference, and diameter of Vietnamese men and their variations among men with erectile dysfunction and other diseases.
