OECD Test Guideline 416: What is a Two-Generation Reproductive Toxicity Study?
The internationally recognized OECD Test Guideline 416 – Two-Generation Study on Reproductive Toxicity is a comprehensive test protocol that allows for a detailed examination of both the parent generation and subsequent generations.
Purpose of the audit
The purpose of this study is to determine the following effects of a chemical substance or product:
- Effects on the reproductive capacity of men and women
- Effects on mating and fertility
- Effects on the development and survival rate of the offspring
- Potential harmful effects on the next generation
This is done using scientific methods.
In this respect, the OECD Test Guideline 416 is an important tool to determine not only short-term effects, but also long-term and hereditary damage.
How is the OECD Test Guideline 416 on reproductive toxicity carried out over two generations?
The test is usually performed on mammalian models such as rats and includes the following phases:
- Preparation of the parents' generation (F0): Female and male animals are treated with the test substance before mating.
- Mating and pregnancy: The F0 generation is mated, the course of pregnancy and birth are observed.
- Investigation of the first generation (F1): The development, survival rate, sex distribution and health status of the born young animals are observed. F1 individuals who have reached a sufficient size are also paired and the process is repeated.
- Second generation (F2) study: The F2 generation is born and detailed health and development assessments are also carried out.
Importance of the two-generation reproductive toxicity test
This comprehensive study is particularly important in the following areas:
- Drug Safety Assessments
- Authorisation procedure for plant protection products and biocidal products
- Analyses of chemical substance and environmental toxicity
- Determination of the effects of cosmetic products on reproductive health
