  • Title: Seminal plasma transferrin concentration in idiopathic oligozoospermia.
    Author: Yoshida K, Uchijima Y, Saitoh H.
    Journal: Urology; 1989 May; 33(5):395-8. PubMed ID: 2496512.
    Abstract:
    To investigate whether or not transferrin production is decreased in the testis of idiopathic oligozoospermia, the seminal plasma transferrin concentration was measured and the values were compared in two groups (15 men of pregnancy-proved normozoospermia and 22 patients with idiopathic oligozoospermia). Seminal plasma transferrin concentration in the pregnancy-proved normozoospermic group was 78.5 +/- 37.9 micrograms/mL, and the concentration in the patients with idiopathic oligozoospermia was 44.4 +/- 37.6 micrograms/mL. There was a significant difference between them (P less than 0.01). The patients with idiopathic oligozoospermia could be divided into two subgroups according to seminal plasma transferrin concentration and serum gonadotropin levels. One group had high transferrin levels with elevated serum gonadotropin levels. The results indicate that the determination of seminal plasma transferrin concentration is one of the useful parameters for evaluation of testicular function and also suggest that additional studies may allow for the subdivision of the patients with so-called idiopathic oligozoospermia.
