Autor: V. Santiemma, Fabio Rossi, P. Romagni, Leopoldo Silvestroni, A. Ferraresi

Publikováno v: Endocrinology. 143:3096-3104

Seminiferous tubule contraction, an important step in the regulation of spermatogenesis and testicular sperm output, is regulated by several agonists. In the present paper, we investigated whether angiotensin II (Ang II) may have a place among them.

Protective effect of esterified glucomannan on aflatoxin-induced changes in testicular function, sperm quality, and seminal plasma biochemistry in rams

Autor: Ataman MB, Dönmez HH, Dönmez N, Sur E, Bucak MN, Coyan K

The aim of this study was to determine the effect of aflatoxin (AF) on spermatologic, biochemical, and testis parameters in rams, and the protective efficiency of esterified glucomannan (EG) co-administered with AF. Thirty-two Merino rams (12-14 mont

Many LH peaks are needed to physiologically stimulate testosterone secretion: modulation by fasting and NPY

Autor: Dominique D. Pierroz, Michel L. Aubert, Ilpo Huhtaniemi, Audrey Aebi

Publikováno v: American Journal of Physiology, Vol. 276, No 4 Pt 1 (1999) pp. E603-10

The pulsatile luteinizing hormone (LH) and testosterone secretions were studied during serial blood collections performed at 7-min time intervals in the male rat. In fed rats, a discontinuous pattern of LH secretion was observed. Periods without secr

Vitellogenin as biomarker for estrogenicity in flounder Platichthys flesus in the field and exposed to 17α-ethinylestradiol via food and water in the laboratory

Autor: Poul Bjerregaard, Bodil Korsgaard, Thomas Aagaard, Louise Leonharder Madsen, Knud Ladegaard Pedersen, Lisette Bachmann Bjerregaard

Publikováno v: Madsen, L L, Korsgaard, B, Pedersen, K L, Bjerregaard, L B, Aagaard, T & Bjerregaard, P 2013, ' Vitellogenin as biomarker for estrogenicity in flounder Platichthys flesus in the field and exposed to 17α-ethinylestradiol via food and water in the laboratory ', Marine Environmental Research, vol. 92, no. December, pp. 79-86 . https://doi.org/10.1016/j.marenvres.2013.09.002

The ability of 17α-ethinylestradiol (EE2) to elevate vitellogenin levels were investigated in male flounder Platichthys flesus and vitellogenin concentrations in flounders from the Danish coastal environment were determined. Male flounders were expo

Vitamin E protection from testicular damage caused by intraperitoneal aluminium

Autor: Kutlubay R, Oğuz EO, Can B, Güven MC, Sinik Z, Tuncay OL

Different forms of Aluminium (Al) are environmental xenobiotics that induce free radical-mediated cytotoxicity and reproductive toxicity. Vitamin E (alpha -tocopherol) is an antioxidative agent that has been reported to be important for detoxificatio

Dose and time relationships of intravenously injected rat recombinant luteinizing hormone and testicular testosterone secretion in the male Rat

Autor: Hakola, K, Pierroz Fuentes, Dominique, Aebi, Alexandre, Vuagnat, Bernard Bruno, Aubert, Michel, Huhtaniemi, I

Publikováno v: Biology of Reproduction, Vol. 59, No 2 (1998) pp. 338-43

The ability of hCG and LH to induce testosterone (T) secretion by Leydig cells is well documented. However, the influence of the pulsatile nature of LH secretion, with varying frequency and amplitude, on T production in vivo is less clear. In our ear

Effects of erythropoietin, bromocryptine and hydralazine on testicular function in rats with chronic renal failure

Autor: Y. Yamamoto, Ikuo Miyagawa, Nikolaos Sofikitis

Publikováno v: Andrologia. 29(3)

We evaluated the effects of chronic renal failure (CRF) on testicular function and semen physiology. A CRF model was created in 48 male rats by performance of five-sixths nephrectomies in two-stage procedures, and a control (group A) by two-stage sha
