Brief Summary

The goal of this observational study is to identify and evaluate the characteristics of Traditional Medicine (TM) syndromes in men aged 18 to 60 with male infertility and oligoasthenoteratozoospermia (OAT) syndrome. The main questions it aims to answer are:

  • What are the common Traditional Medicine syndromes and symptoms associated with male infertility based on Traditional Medicine literature?
  • What are the specific Traditional Medicine syndromes and symptoms found in men with OAT syndrome at Binh Dan Hospital when analyzed using Latent Tree Models? The research will be conducted in two phases:
  • Phase 1 (Literature Review): Researchers will collect and analyze Traditional Medicine texts to list the symptoms and syndromes related to male infertility. This phase will help create a standardized clinical survey.
  • Phase 2 (Clinical Survey): Researchers will recruit 300 male participants with OAT syndrome.
  • Participants will answer a survey questionnaire about their Traditional Medicine symptoms.
  • Researchers will apply Latent Tree Models (a mathematical approach) to the collected data to objectively classify the TM syndromes.

Outcome Measures

Primary Outcomes (1)

  • Classification of Traditional Medicine Syndromes

    The identification and classification of male infertility patients with Oligo-Astheno-Teratozoospermia into distinct TCM syndrome subtypes using the Latent Tree Model (LTM) and the Extension-Adjustment-Simplify-Transfer (EAST) algorithm. The analysis uses clinical symptoms and signs as features to cluster patients into groups.

Study Arms (1)

Male Infertility Patients with OAT Syndrome

* Men aged 18 to 60 years who are diagnosed with male infertility and present with Oligoasthenoteratozoospermia (OAT) syndrome. According to the World Health Organization (WHO) standards, OAT is defined by the following concurrent semen parameters: * Oligozoospermia: Sperm concentration \< 15 million/mL or total sperm count \< 39 million. * Asthenozoospermia: Progressive motility \< 32%. * Teratozoospermia: Normal morphology \< 4%. * Participants are recruited from the Department of Andrology at Binh Dan Hospital, Ho Chi Minh City. The study excludes individuals with: * Genetic or chromosomal abnormalities (e.g., Klinefelter syndrome, XYY syndrome). * Structural abnormalities of the reproductive organs. * Azoospermia (no sperm in the ejaculate). * Recent use (within the last 3 months) of medications known to affect spermatogenesis, such as anabolic steroids or certain calcium channel blockers. * Inability to communicate or participate in the survey.

Sampling MethodNon-Probability Sample
Study Population

The study population is a clinical cohort of men aged 18 to 60 years who seek medical consultation or treatment for reproductive health issues at the Department of Andrology, Binh Dan Hospital, Ho Chi Minh City. The specific population focuses on individuals diagnosed with male infertility and Oligoasthenoteratozoospermia (OAT) syndrome, characterized by a concurrent reduction in sperm count, motility, and normal morphology according to the World Health Organization (WHO) standards .

You may qualify if:

  • Male patients aged between 18 and 60 years.
  • Diagnosed with male infertility by an andrology specialist according to World Health Organization (WHO) standards.
  • Semen analysis results meet the diagnostic criteria for Oligoasthenoteratozoospermia (OAT) syndrome.
  • Voluntary agreement to participate in the research and signed Informed Consent Form.

You may not qualify if:

  • Infertility caused by genetic or chromosomal abnormalities, including but not limited to: Klinefelter syndrome, Sandberg mosaic syndrome (46 XY/47 XXY), or XYY syndrome.
  • Presence of structural abnormalities of the reproductive organs.
  • Patients with Azoospermia (absence of sperm in the ejaculate) as defined by WHO 2021 standards.
  • Use of medications affecting spermatogenesis within the last 3 months, including: cannabinoids, hydantoins, valproate, anabolic steroids, cimetidine, colchicine, spironolactone, nitrofurantoin, sulfasalazine, or calcium channel blockers.
  • Inability to understand or answer survey questions due to physical or mental limitations (e.g., mutism, deafness, intellectual disability, coma, or being on a ventilator in the ICU).
  • Lack of cooperation during the clinical examination and interview process.
