OECD 443: Extended one-generation reproductive toxicity study (EOGRTS)
OECD 443: Extended one-generation reproductive toxicity study (EOGRTS)
The objectives of the extended one generation study (OECD 443) are to determine the adverse reproductive and developmental effects that may occur as a result of pre- and postnatal chemical exposure as well as an evaluation of systemic toxicity in pregnant and lactating females and young and adult offspring.
This study evaluates reproductive performance, necropsy, organ weights, sperm motility/counts/morphology, histopathology and ovarian follicle counts of the offspring (F1 generation). The OECD 443 study is primarily conducted in rats via dietary or oral gavage routes of administration.
About our nonclinical animal research models: We provide the utmost care for our research animals and actively pursue advances in animal welfare. As well as ensuring the highest scientific, ethical and regulatory standards, selection of appropriate animal research models for development research is critical to developing safe and effective treatments, devices and products that protect and save lives. Just as we have ethical committee oversight for human trials, we have ethical committees overseeing all aspects of our global animal care and use programs. All of our core, nonclinical facilities are accredited by AAALAC. Learn more about our commitment to replacing, reusing and refining nonclinical research models.
