Autor: Gert R. Dohle, Laméris, Frank H. Pierik, Timmers, Vreeburg, Weber, J. H. van Roijen, Stijnen
Publikováno v: International Journal of Andrology. 21:256-260
The debate regarding the efficacy of varicocele ligation for improvement of semen parameters and pregnancy rates is ongoing. In addition, no consensus exists as to the benefit of treatment of subclinical varicoceles. The aim of this study was to inve

Publikováno v: Urological Research, January, 1, 31, 22-24
Bilateral obstruction of the male reproductive tract is suspected in men with azoospermia, normal testicular volume and normal FSH. A testicular biopsy is required to differentiate between an obstruction and a testicular insufficiency. Unilateral or

During mammalian spermatogenesis, the chromatin of the spermatogenic cells is profoundly reorganized. Somatic histones are partly replaced by testis-specific histones. These histones are then replaced by transition proteins and finally by protamines.

Comparison of the response of rat testis and accessory sex organs to treatment with testosterone and the synthetic androgen methyltrienolone (R1881)
Autor: J H, van Roijen, M P, Ooms, R F, Weber, A O, Brinkmann, J A, Grootegoed, J T, Vreeburg
Publikováno v: Journal of andrology. 18(1)
We have studied the ability of the synthetic androgen methyltrienolone (R1881) to maintain testis and accessory organ weights, as compared to the effect of testosterone propionate (TP). In contrast to TP, R1881 is not metabolized and does not signifi

Inactivation of the HR6B ubiquitin-conjugating DNA repair enzyme in mice causes male sterility associated with chromatin modification
Autor: Jos W. Hoogerbrugge, J van Klaveren, Marcel Koken, J. de Wit, C.G van Gurp, J.H.J. Hoeijmakers, M. Vermey, Henk P. Roest, Willy M. Baarends, Dirk Bootsma, J. H. van Roijen, J. T. M. Vreeburg, J. A. Grootegoed
Publikováno v: Cell, 86(5), 799-810. Cell Press
The ubiquitin-conjugating yeast enzyme RAD6 and its human homologs hHR6A and hHR6B are implicated in postreplication repair and damage-induced mutagenesis. The yeast protein is also required for sporulation and may modulate chromatin structure via hi

Sexual arousal and the quality of semen produced by masturbation
Autor: J. T. M. Vreeburg, R. F. A. Weber, Gert R. Dohle, A.K. Slob, J. H. van Roijen, Woet L. Gianotten, A. T. M. van der Zon
Publikováno v: Human reproduction (Oxford, England). 11(1)
The influence of sexual arousal on the quality of semen produced by masturbation was investigated. One group of 29 patients referred to our andrology outpatient clinic (group A) and one group of 14 healthy potential sperm donors filled out a question

Androgen receptor immunoexpression in the testes of subfertile men
Autor: J H, Van Roijen, S, Van Assen, T H, Van Der Kwast, D G, De Rooij, W J, Boersma, J T, Vreeburg, R F, Weber
Publikováno v: Journal of andrology. 16(6)
The localization and intensity of androgen receptor immunostaining was studied in the testes of 37 subfertile men with oligozoospermia and normal serum gonadotropin levels using a polyclonal antibody raised against a synthetic peptide corresponding t
