Male infertility of genetic origin

Last edited: 4/15/2026

Overview

Male infertility of genetic origin encompasses conditions where genetic factors significantly contribute to impaired spermatogenesis or sperm function, often leading to reduced fertility or sterility 1.

Diagnosis

  • Genetic testing including karyotyping, Y-chromosome microdeletions analysis, and gene sequencing for specific mutations (e.g., CFTR, KAL1) 1.
  • Semen analysis to assess sperm count, motility, and morphology 1.
  • Hormonal evaluation (FSH, LH, testosterone) to identify hormonal imbalances 1.
  • Recommendations vary 2.

    • Management

  • Genetic counseling to discuss implications and options, including assisted reproductive technologies (ART) 1.
  • Assisted reproductive technologies such as intracytoplasmic sperm injection (ICSI) for severe cases 1.
  • Pharmacological interventions like testosterone replacement therapy for hypogonadism (dose varies based on clinical need) 1.
  • No specific drug classes or doses beyond general ART protocols are detailed in the provided abstracts 1.

    • Special Populations

  • Pregnancy considerations: Focus on genetic counseling for potential transmission risks 1.
  • Pediatrics: Limited data; focus on early identification and genetic counseling for future fertility issues 1.
  • Elderly: Age-related decline may exacerbate genetic infertility issues; ART options remain viable 1.
  • Comorbidities: Management should address underlying conditions affecting fertility, integrating specialized care 1.

    • Key Recommendations

  • Offer comprehensive genetic testing and counseling to patients with suspected genetic male infertility (Evidence: Moderate) 1.
  • Utilize assisted reproductive technologies, particularly ICSI, for treatment of severe cases (Evidence: Moderate) 1.
  • Consider hormonal assessments to guide appropriate pharmacological interventions (Evidence: Weak) 1.
