Background Twenty-three men (45 testes) with azoospermia underwent percutaneous testicular biopsy under local anaesthesia. Methods In all but one of the 45 testes two biopsies were taken close to each other, one with a 16 gauge (n = 44) and another w

Twenty-two cryptorchid boys previously unsuccessfully treated with human chorionic gonadotropin (hCG) were operated. Testicular biopsies were taken and a routine orchidopexy was performed in each case. As controls eight cryptorchid boys without prior

Rabbit spermateleosis is subdivided into ten stages (A to J) based upon fine structure. Spherical spermatids in stages A to D correspond to the Golgi phase and the cap phase of Leblond and Clermont (1952a). Elongating spermatids in stage E through th

The fine structure of rabbit Spermatogonia and primary spermatocytes in meiotic prophase has been studied with different methods of preparation, including a technique for acid phosphatase activity. The spermatogonial cytoplasm is rich in free ribosom

The effects on rabbit spermatogenesis of experimental cryptorchidism for twenty-four hours were studied with the light microscope in material taken immediately, or at intervals from two to thirty-five days after the exposure. Up to twelve days after

The structure of glandular cells in the anterior lobe of the rabbit prostate was reinvestigated, especially after fixation by vascular perfusion with glutaraldehyde. The lumina of the gland contain abundant globules of an amorphous material surrounde

The frequency of gonadal tumors in intersex patients with a karyotype including a Y chromosome is very high. In other at-risk groups, testicular germ cell tumors have been shown to be preceded by carcinoma in situ (CIS) changes. We investigated gonad

The plasmalemma of the mammalian spermatozoon contains a number of specific proteins, some of which have a clear regional distribution (see ref. 1–5). It is reasonable to assume that one or more sperm membrane proteins are involved in the initial r
