Thesis Topics in Infertility

Based on the most recent international consensus and guideline development work, prioritize thesis research in areas that address critical gaps in prevention, diagnosis, treatment optimization, and access to care—particularly focusing on male factor infertility, oxidative stress mechanisms, psychosocial impacts, and low-cost ART delivery in resource-limited settings.

High-Priority Research Areas from International Consensus

The 2025 ESHRE priorities and 2020 international consensus work 1, 2 identify twelve critical research domains that should guide thesis topic selection:

1. Male Infertility Research Gaps

Male factors contribute to 50% of infertility cases 3, yet fundamental questions remain unanswered:

  • Oxidative stress and sperm DNA fragmentation: Current guidelines note that while oxidative stress affects sperm quality and DNA integrity 3, standardized testing methods are lacking and routine ROS measurement requires validation through well-designed RCTs 3. A thesis examining standardized protocols for measuring oxidative stress or validating interventions to reduce sperm DNA fragmentation would address a critical clinical need.

  • Testicular versus ejaculated sperm for ICSI: Evidence suggests testicular sperm has lower DNA fragmentation than ejaculated sperm 3, but heterogeneity in studies prevents firm recommendations. Research validating TESE outcomes in men with elevated SDF represents a high-impact opportunity.

  • Genetic and epigenetic factors: With karyotype abnormalities being the most common known genetic cause of male infertility 4, research into novel genetic markers or epigenetic modifications affecting spermatogenesis remains understudied.

2. Prevention and Risk Factor Modification

Both major guidelines 3, 4 emphasize that current data on lifestyle and environmental risk factors are limited:

  • Quantifying modifiable risk factors: Research establishing causal relationships between specific occupational exposures, medications, or lifestyle factors and infertility outcomes
  • Intervention studies: RCTs testing whether modification of identified risk factors (smoking cessation, weight loss, reducing environmental toxin exposure) improves fertility outcomes
  • Fertility preservation strategies: Particularly before cancer treatment or in high-risk populations

3. Optimizing Fertility Treatments

The 2024 AUA/ASRM guideline 4 and 2025 EAU guideline 3 highlight treatment optimization needs:

  • Varicocelectomy outcomes: While microsurgical varicocelectomy receives grade A recommendation 5, research on patient selection criteria and predictors of success would refine clinical practice
  • Medical therapies for oligozoospermia: Antioxidant therapy currently has limited evidence (grade C) 5. Well-designed RCTs examining specific antioxidant regimens could elevate this evidence base
  • Ovarian stimulation protocols: Comparing mild versus conventional stimulation in different patient populations

4. Psychosocial Impact and Support

The 2020 international consensus 2 specifically prioritized research addressing emotional and psychological impacts of infertility:

  • Mental health interventions: Testing structured psychological support programs and measuring their impact on treatment outcomes and quality of life
  • Couple-centered care models: Research examining how simultaneous evaluation and treatment of both partners affects outcomes and relationship satisfaction
  • Cultural and gender-specific impacts: Particularly in settings where infertility carries severe social stigma 6

5. Access, Equity, and Low-Cost ART

This represents perhaps the most impactful research area given that 186 million people worldwide experience infertility 6, yet ART remains inaccessible in most of sub-Saharan Africa and many low-resource settings:

  • Low-cost IVF protocols: Research validating simplified IVF systems combined with mild stimulation protocols 7. The 2026 WHO guideline 8 emphasizes equity in fertility care as part of universal health coverage
  • Point-of-care diagnostic tools: Validating mail-in or point-of-care semen testing accuracy 4 to improve diagnostic access
  • Implementation science: Research on barriers to establishing fertility services in resource-poor settings and strategies to overcome them
  • Cost-effectiveness analyses: Comparing different treatment approaches in various healthcare systems

6. Preimplantation Development and Early Pregnancy

The 2025 ESHRE priorities 1 specifically highlight deepening knowledge in:

  • Embryo selection methods: Non-invasive markers of embryo viability
  • Endometrial receptivity: Mechanisms and biomarkers
  • Early pregnancy loss prevention: Particularly in recurrent miscarriage

Methodological Considerations

Strong thesis topics should employ diverse methodologies 2:

  • Laboratory-based science (molecular mechanisms, biomarker discovery)
  • Quantitative research (RCTs, cohort studies, cost-effectiveness analyses)
  • Qualitative research (patient experiences, barriers to care)
  • Population science (epidemiology, health services research)

Critical Gaps Requiring Immediate Attention

The 2026 WHO guideline 8 notes that most recommendations are conditional due to absent or very low-certainty evidence. Thesis research that generates high-quality evidence in any of the WHO's 40 recommendation areas would have immediate clinical impact.

Specific gaps include:

  • Optimal diagnostic algorithms for unexplained infertility
  • Treatment of uterine cavity abnormalities
  • Management of tubal disease
  • Interventions for PCOS-related infertility

Practical Thesis Selection Strategy

Choose topics that:

  1. Address questions explicitly identified as research priorities by major international societies 1, 2
  2. Have potential to change clinical practice (moving conditional recommendations to strong recommendations)
  3. Focus on prevention or improving access, which have broader population impact than treatment optimization alone
  4. Include patient-centered outcomes (quality of life, psychological wellbeing, cost) rather than solely biological endpoints
  5. Are feasible within your institutional resources and timeline

Avoid topics that:

  • Merely describe associations without testing interventions
  • Focus on rare conditions with limited generalizability
  • Duplicate existing high-quality research without adding novel insights
  • Lack clear clinical or public health relevance

The bibliometric analysis 9 shows that fertilization in vitro, adverse effects, spermatozoa, pregnancy rate, and treatment outcomes are the most frequently studied topics—consider whether your thesis can address understudied areas within these domains or pivot to genuinely neglected research questions.
