Summary: Subcutaneous treatment of immature male rats with an estrogen precursor, 19-hydroxy-testosterone (19-OHT), at a daily dose of 1 mg/animal for 14 days leads to a significant decrease in the weight of testis, ventral prostate and seminal vesic

The Influence of Pharmaceutical Compounds on Male Fertility*

Autor: Traore I, Friedmund Neumann, S. H. Hasan, Diallo Fa, B. Schenck

Publikováno v: Andrologia. 8:203-235

1. Steroid hormones can affect spermatogenesis and thereby fertility directly and/or indirectly. All antigonadotropically active steroids inhibit spermatogenesis via inhibition of gonadotropin secretion, mainly that of H. Androgens and steroids occur

Short-Term Effects of an LHRH-Agonist alone or in Combination with Testosterone Propionate or Indomethacin on Rat Testes

Autor: U.-F. Habenicht, M. F. El Etreby, Friedmund Neumann

Publikováno v: Andrologia. 19:602-613

Summary: The treatment of adult male Wistar rats with a LHRH-agonist (lutrelin Wyeth/WY 40972) resulted in severe damage of the seminiferous tubules as well as in remarkable changes of the blood vessels within 24 hours. First striking signs of altera

Pharmacology of Cyproterone Acetate — A Short Review

Autor: Friedmund Neumann

Publikováno v: Antiandrogens in Prostate Cancer ISBN: 9783642457470

Cyproterone acetate (CPA) was the first antiandrogen to be used in clinical practice. The antiandrogenic activity was discovered in 1962/ 1963 — 30 years ago. But the term “antiandrogen” was not really new [for review see 1].

Comparative evaluation of the dissociation rate between the vaginotrophic and uterotrophic activities of 1-hydroxy-1,3,5(10)-estratriene derivatives with natural and unnatural configuration at C8 using ovariectomized mice

Autor: Yukishige Dr Nishino, Klaus Prezewowsky, Friedmund Neumann, Rudolf Prof. Wiechert

Publikováno v: Steroids. 28:325-337

Influences on estrogenic.activities of 1-hydroxylation and C8-isomerization in the molecules of naturally occurring estrogens have been studied. All compounds tested behaved qualitatively in the same manner as estradiol, as far as the decrease in the

Pharmacological basis for clinical use of antiandrogens

Autor: Friedmund Neumann

Publikováno v: Journal of Steroid Biochemistry. 19:391-402

Summary The first antiandrogen which was also of clinical interest—cyproterone acetate (CPA)—was discovered at the beginning of the 60th. CPA acts in all target organs for androgens and in principle affects all functions which are governed or inf

Development of a model for the induction of estrogen-related prostatic hyperplasia in the dog and its response to the aromatase inhibitor 4-hydroxy-4-androstene-3,17-dione: Preliminary results

Autor: M. El Fathy Etreby, Klaus Schwarz, Friedmund Neumann, Hans‐U. Schweikert, U.-F. Habenicht

Publikováno v: The Prostate. 8:181-194

Although the presence of the testes is an absolutely necessary prerequisite for benign prostatic hyperplasia (BPH) to occur, the role of androgens in the cause of BPH is still controversial. There are increasing signs for a decisive role of estrogens

8α-estra-1,3,5(10)-triene-1,3,17β-triol as a special type of estrogen having a high vaginotrophic activity and a low uterotrophic activity in castrated mice

Autor: Friedmund Neumann, Yukishige Dr Nishino

Publikováno v: Steroids. 30:179-192

The vaginotrophic and uterotrophic activities of 1-OH-8-alpha-E2 and its acetate in comparison with E2 and E3 were assessed on the basis of the effect on weights, water/fat-and RNA/DNA-contents of mouse vagina and uterus. The multiple doses of 8 alph
