Abstract

OBJECTIVE: To investigate the relationship between hand and finger measurement values and semen parameters. MATERIAL and METHODS: Ninety patients who applied to the male infertility polyclinic of our hospital in 2018 were included in the study prospectively. Finger and hand measurement values (right 2D, right 4D, right hand width, right hand length, left 2D, left 4D, left hand width, left hand length) were determined using a ruler with 1 mm accuracy. Other parameters were calculated by using these digit ratio values. The relationship between semen parameters and measurement values were analysed by bi-variate correlation test (Spearman). P value <0.05 was considered statistically significant. RESULTS: Left and right hand width has a negative correlation with semen parameters and left hand length and finger 2D:4D ratios has positive correlations. CONCLUSION: Contrary to the literature data, a positive correlation was found in our study between the semen parameters and the right 2D:4D and left 2D:4D ratios, which are shown as indirect determinants of testosterone exposure in the prenatal period. Interestingly, the right (4 parameters) and left (5 parameters) hand widths were the measurement values indicating the most negative correlation with the semen parameters. Can hand width be a new determinant for testosterone exposure in the prenatal period? It is clear that prospective and randomized studies with more cases are needed to answer this question and to clarify the exact pathophysiology.

Özet

AMAÇ: Parmak ve el ölçüm değerleri ile semen parametreleri arasındaki ilişkiyi incelemek. GEREÇ ve YÖNTEM: Çalışmamıza hastanemiz erkek infertilitesi polikliniğine 2018 yılında başvuran 90 hasta prospektif olarak alındı. Ondalık 1 mm duyarlı cetvelle parmak ve el ölçüm değerleri (sağ 2D, sağ 4D, sağ el genişliği, sağ el uzunluğu, sol 2D, sol 4D, sol el genişliği, sol el uzunluğu) saptandı. Bu değerlerle parmak oran değerleri (sağ 2D:4D oranı, sol 2D:4D oranı) hesaplandı. Parmak oran değerleriyle ise sağ-sol oran farklılıkları (sağ 2D:4D - sol 2D:4D değeri (Dr-l), sağ 2D:4D/sol 2D:4D oranı (Dr/l) ve 2D:4D asimetri indeksi [(sol 2D:4D - sağ 2D:4D)/(sol 2D:4D + sağ 2D:4D)] hesaplandı. Semen analizi parametreleri ile ölçüm değerleri arasındaki ilişki bi-variate korelasyon testi (spearman) ile incelendi. P değeri <0,05 istatistiksel olarak anlamlı kabul edildi. BULGULAR: Semen parametreleri ile sağ ve sol el genişliği arasında negatif ilişki, sol el uzunluğu ve parmak 2D:4D oranları ile pozitif ilişki saptandı. SONUÇ: Prenatal dönemdeki testosteron maruziyetinin indirekt belirleyicisi olarak gösterilen sağ 2D:4D ve sol 2D:4D oranı ile semen parametreleri arasında literatür verileri ışığında negatif korelasyon çıkması beklenirken, bizim çalışmamızda pozitif korelasyon çıkmıştır. Ve özellikle ilginç olan sağ (dört parametre) ve sol (beş parametre) el genişliğinin ise en fazla semen parametreleri ile negatif korelasyon içeren ölçüm değeri olmasıdır. El genişliği prenatal dönemdeki testosteron için yeni bir belirleyici olabilir mi? Bu soruyu yanıtlamak ve kesin patofizyolojiyi aydınlatmak için daha çok sayıda vaka içeren, prospektif ve randomize çalışmalara ihtiyaç olduğu açıktır.
