  • Title: [Leydig cell function in idiopathic oligozoospermia].
    Author: Lunglmayr G, Kratzik C, Biegelmayer C.
    Journal: Wien Klin Wochenschr; 1984 Sep 14; 96(17):651-4. PubMed ID: 6440369.
    Abstract:
    Repeated blood sampling at 10-minute intervals over a 4-hour period (15.00 until 19.00) for simultaneous determination of FSH, LH and testosterone was carried out in 7 normospermic men and 8 patients presenting with idiopathic oligozoospermia. Fluctuations of LH and testosterone were observed within the 4-hour sampling period. Only minor alterations of FSH were found. Planimetric assessment of the areas under the curves of FSH, LH and testosterone did not show any significant difference in FSH. Testosterone was found to be significantly decreased in the oligospermic group (p less than 0.025), while LH showed a tendency to be increased (p less than 0.1). These results point out that single determinations of LH and testosterone do not provide exact information, due to the wide range of hormone fluctuation. Serial sampling of the hormones demonstrates Leydig cell dysfunction in patients with moderate idiopathic oligozoospermia.
