2D:4D Ratio vs Semen Parameters
Sponsor: Suleyman Demirel University
Summary
The aim of this study evaluate the relationship between sperm count and the second-to-fourth digit ratio (2D:4D) in male patients. Additionally, the associations between body mass index, hormonal profile, hand morphometric measurements, and semen parameters were investigated. Study hypotheses: H1. There is a significant relationship between the second-to-fourth digit ratio (2D:4D) and sperm count in male patients. H2. There is a significant relationship between body mass index (BMI) and semen parameters in male patients. H3. There is a significant relationship between hormonal profile and semen parameters in male patients. H4. There is a significant relationship between hand morphometric measurements and semen parameters in male patients. H5. There is a significant relationship between the second-to-fourth digit ratio (2D:4D) and hormonal profile in male patients.
