Pesticide registration toxicology test method
Part 24. Two generations of reproductive toxicity test
1 Scope
This part of GB/T 15670 specifies the basic principles, methods and requirements for the two generations of reproductive toxicity tests.
This section applies to two generations of reproductive toxicity tests for pesticide registration.

3 terms and definitions
The following terms and definitions apply to this document.
3.1
Reproductive toxicity reproductivetoxicity
The parental or male reproductive function damage or reproductive capacity caused by the test substance decreased.
3.2
Developmental toxicity
The offspring of a pregnant animal exposed to the test substance are at birth, perinatal and postnatal manifestations of the body defect or dysfunction.
4 Purpose of the test
Used to detect the impact of the test substance on female and male animal reproductive function, such as gonadal function, estrous cycle, mating behavior, pregnancy, childbirth,
Breastfeeding and weaning and the growth and development of offspring. And may provide information on the developmental toxicity of the test substance, such as birth defects, death and abnormalities
Shape and so on.
5 Test Overview
The male and female animals were divided into several dose groups, in order to evaluate the effect of the test substance on the sperm production, the exposure period is the parent male animal (P) to
Less covering a complete sperm formation cycle (mice about 56 days, rats about 70 days). The parental female (P) animal has at least two complete hairs
Love cycle. Thereafter, the mating animals (P) were given the test substance, and the female parent continued to administer the test substance until the F1 generation of weaning during pregnancy. F1 break
After the milk, the test substance was continuously administered from the offspring of F1, adolescence, mating, generation F2 of the offspring until the F2 generation weaned to evaluate the test
Two generations of reproductive toxicity effects.
