Testing for Chemicals Products


Our testing solutions ensure the practical implementation of REACH requirements on developmental and reproductive toxicity testing requirements according tonnage marketed per year.


Where there are no concerns over reproduction or development REACH calls to start with the screening study (OECD421/422) at this tonnage.

Where there are serious concerns about the potential for adverse effects on fertility or development, either a pre-natal developmental toxicity study or a two- or extended one generation reproductive toxicity study may be proposed instead of the screening study.


REACH requires a pre-natal developmental toxicity study in one species (usually rat) If the 28-day or 90-day study indicates adverse effects on reproductive organs or tissues conduct a two-generation or extended one-generation reproductive toxicity study in one species.


REACH requires a pre-natal developmental toxicity study in one species (usually rat). Need for a second species judged on a case-by-case basis Two-generation or extended one-generation reproductive toxicity study in one species. Need for a second species judged on a case-by-case basis.

Our team and Experience

Vivotecnia offers the high level of scientific expertise needed to address special DART regulatory studies requirements, including fertility, developmental toxicity (teratology), juvenile studies and multigenerational reproductive studies. Tests can be performed by using a variety of administration routes ranging from dermal to intravenous infusion. These designs are customized to individual Sponsor needs aligned with regulatory guidance, including FDA, EMEA, and OECD standards.


At Vivotecnia we are experienced and skilled in assessing all necessary endpoints:

  • Necropsy
  • C-sections
  • Uterine examinations

Post-Life fetal evaluations in multiple species and strains

  • External morphology
  • Visceral
  • Skeletal

Neurobehavioral assessments

  • Motor activity
  • Learning
  • Memory
  • Acoustic startle response

Sperm assessments
