Description
Curator's Comment: Description was created based on several sources, including https://de.wikipedia.org/wiki/4-tert-Octylphenol

4-tert-octylphenol (OP) is a compound of the class of endocrine disruptors. In 2011 it was added to the list of Substances of Very High Concern (SVHCs) based on the results of an evaluation of the effects of 4-tert-octylphenol (OP) on the growth, survival, and steroid hormone and cAMP production by isolated 14-day-old rats (Sprague-Dawley) ovarian follicles. During a 5-day culture with isolated ovarian follicles, OP decreased estradiol and testosterone secretion in a dose-dependent manner, decreased forskolin-induced cAMP levels, and showed no effect on aromatase activity.
