  • Title: Serum gonadotropins and testosterone in infertile patients with varicocele.
    Author: Rege N, Phadke A, Bhatt J, Khatri N, Sheth A, Joshi U, Vaidya R.
    Journal: Fertil Steril; 1979 Apr; 31(4):413-6. PubMed ID: 428587.
    Abstract:
    Serum concentrations of gonadotropins and testosterone in 25 infertile men with varicocele were compared with those in control men and men with idiopathic oligo-azoospermia. No significant difference was found in values of serum follicle-stimulating hormone (FSH) (14.9 +/- 13.6 mIU/ml), luteinizing hormone (LH) (24.9 +/- 19.1 mIU/ml), and testosterone (5.0 +/- 2.1 ng/ml) when the group with varicocele was compared with either the control group (FSH, 7.0 +/- 3.2 mIU/ml; LH, 23.6 +/- 16.0 mIU/ml; testosterone, 5.3 +/- 1.8 ng/ml) or the group with idiopathic oligo-azoospermia (FSH, 23.0 +/- 22.69 mIU/ml; LH, 36.7 +/- 24.1 mIU/ml; testosterone, 5.31 +/- 2.3 ng/ml). However, compared with the control group, there was a significant elevation of serum FSH levels in patients with varicocele whose testicular biopsy score counts were between 1 and 4. The importance of preoperative determination of the serum FSH level is discussed.
