Fertility and Early Embryo Development Toxicity Evaluation
Fertility and early embryo development (FEED) toxicity evaluation is the first segment of developmental and reproductive toxicology evaluation. Our company has many years of experience in rare disease drug safety evaluation services and has the resources and capabilities to provide clients with custom study designs. Our safety evaluation experts provide unparalleled fertility and early embryotoxicity evaluation services.
Introduction to Fertility and Early Embryo Development Toxicity Evaluation
Fertility and early embryonic development (FEED) toxicity evaluation refers to the evaluation of effects on mating, estrous cyclicity, spermatogenesis, and ability to produce a viable implant, thereby evaluating their reproductive toxicity to animals and providing a reference for related research. In fertility and early embryonic development toxicity evaluation, body weight and food intake should be paid special attention. Abnormalities in body weight and food intake will directly affect subsequent mating behavior.
Toxicity Symptoms of Fertility and Early Embryo Development
The toxicity of drugs can interfere with any aspect of reproductive development and cause damage. It may have indirect toxic effects through the endocrine system, or it may regulate the endocrine system through the nervous system and act on the reproductive development process through the hypothalamus. Drug toxicity can cause the following common symptoms of fertility and early embryonic development:
- Sexual dysfunction
- Abnormal ovulation
- Menstrual disorders
- Ovarian atrophy
- Fewer pregnancies
- Embryonic death
- Infertility
- Testicular atrophy
- Low sperm count

With many years of experience, our company provides clients with reasonable fertility and early embryonic development toxicity evaluation protocols. Our animal platform provides mice, rabbits, rats, and other experimental animals and combine the protocols to develop different administration routes, including dietary, dermal, gavage, vaginal, intramuscular, intraperitoneal, intravenous, subcutaneous, rectal, etc. Combined with our bioanalytical platform, we provide clients with a one-stop evaluation service.
