Teratogenicity / Reproductive Toxicity Study
Aprofood's toxicology team runs teratogenicity and reproductive toxicity studies on raw pollen, wall-broken pollen, extracts and finished products, supplying the evidence that peony pollen products do not harm reproduction or fetal development. Each study reports fertility, pregnancy outcome and offspring development together with a clear interpretation. Product developers can use these results with confidence for ingredient development, registration and market entry.
About Teratogenicity & Reproductive Toxicity
Abnormal development of the embryo or fetus caused by a substance is known as teratogenicity. Reproductive toxicity is the broader term, covering harm to fertility, mating behavior, pregnancy, lactation and offspring growth. A sensitive window of development can be affected permanently by exposure, which is why food ingredients meant for long-term or general use are expected to undergo these studies. The designs follow the reproductive cycle step by step, from germ cell formation and fertilization through implantation, organ formation and birth to weaning. Although peony pollen has a long tradition as a food and health material, wall-broken pollen, extracts and concentrates contain more active compounds, such as flavonoids and plant hormone-like substances, and their composition differs from that of raw pollen. For this reason, documented reproductive safety data are still requested by regulators, since a history of use cannot prove safety and only a standardized study can exclude risks to fertility and fetal development.
Our Service
With extensive toxicological expertise, Aprofood designs studies to address industry standards and regulatory requirements. Testing follows internationally recognized frameworks, such as OECD Test Guidelines and applicable national food safety standards, while study parameters are tailored to the test material, intended use, and target market. For peony pollen products, multiple study approaches can be selected to evaluate potential teratogenic and reproductive toxicity, as outlined below.
| Test Method |
Description |
| Prenatal Developmental Toxicity Study |
- Guideline: OECD 414
- Test system: pregnant rats or rabbits dosed orally during the period of organ formation
- Outcome: detects maternal toxicity, embryo-fetal death, growth retardation and external, visceral and skeletal malformations
- Application: core teratogenicity assessment of all peony pollen products
|
| Two-Generation Reproduction Toxicity Study |
- Guideline: OECD 416
- Test system: rats dosed orally across two generations, from premating through weaning
- Outcome: evaluates fertility, gestation, lactation and offspring growth and development
- Application: full reproductive assessment for products intended for long-term use
|
| Reproduction/Developmental Toxicity Screening Test |
- Guideline: OECD 421 / 422
- Test system: male and female rats dosed before mating, during mating and through early lactation
- Outcome: preliminary information on fertility, pregnancy and early offspring development
- Application: initial screening of extracts and concentrated products
|
| Extended One-Generation Reproductive Toxicity Study |
- Guideline: OECD 443
- Test system: rats dosed before mating through weaning of the first generation, with extended offspring assessment
- Outcome: evaluates reproductive performance, offspring development, and neurological and immune endpoints
- Application: efficient alternative to the two-generation study when regulators accept it
|
| Fertility and Early Embryonic Development Study |
- Guideline: ICH S5(R3) design principles
- Test system: male and female rats dosed before mating and until early pregnancy
- Outcome: detects effects on mating, fertility and implantation
- Application: targeted evaluation of fertility effects
|
| Pre- and Postnatal Development Study |
- Guideline: ICH S5(R3) design principles
- Test system: pregnant rats dosed from implantation through weaning
- Outcome: evaluates maternal function and offspring survival, growth and development
- Application: assessment of late pregnancy and lactation effects

Our Applications of Teratogenicity / Reproductive Toxicity Studies
Teratogenicity and reproductive toxicity studies can support peony pollen products throughout development, safety assessment, and regulatory evaluation. Aprofood provides study options suited to different product types, development stages, intended uses, and target markets, helping generate relevant safety data for product advancement and regulatory needs.
| Application |
Description |
| Raw Material & Processing Safety |
Safety confirmation for wall-broken pollen, ensuring that mechanical cell disruption or high temperature processing creates no genotoxic degradation byproducts. |
| Extract Safety Profile |
Evaluation of concentrated extraction fractions to determine safe exposure thresholds and verify that concentrated active compounds do not trigger DNA damage. |
| Novel Food Registration |
Mandatory genotoxicity data packages required for regulatory approval submissions across target international markets. |
| Finished Product Verification |
Assessment of final commercial forms including tablets, capsules, powders, and beverages to confirm that matrix mixing and excipients do not induce genotoxic effects. |
| Formulation Screening |
Comparison of different processing routes, regional origins, or production batches to select the safest formulation prior to large scale investment. |
Our Workflow of Teratogenicity / Reproductive Toxicity Study
01
Study Design
We review the test material, intended use, target market, and study objectives, then develop a study protocol and quotation for confirmation. The protocol specifies dose levels, animal numbers, study duration, and applicable guidelines.
02
Sample Preparation
The test material is characterized and prepared into a suitable dosing formulation. Homogeneity and stability are assessed to ensure consistent and representative dosing throughout the study.
03
Animal Acclimation
Healthy animals are acclimated under controlled laboratory conditions before dosing. Temperature, humidity, lighting, diet, housing, and general health are monitored throughout the acclimation period.
04
Dosing & Observation
Animals receive the test material by oral gavage at the specified dose levels and are monitored throughout the study period. Clinical signs, behavior, food intake, body weight, and other relevant observations are recorded at scheduled intervals.
05
Necropsy & Data Analysis
Gross necropsy is performed at study completion, with histopathological evaluation conducted when required. Study data are analyzed to identify treatment-related findings and assess overall toxicity.
06
Final Reporting
A comprehensive report summarizes study procedures, observations, toxicity findings, and conclusions. Raw data and recommendations for further safety or toxicological studies are provided where applicable.

Frequently Asked Questions (FAQs)
Q1: Is my peony pollen product suitable for a reproductive toxicity study?
A1: Raw pollen, wall-broken pollen, extracts, powders, tablets and capsules are all accepted. Solubility and physical properties decide how each material is turned into a dosing formulation. If your product has an unusual form, send us the details and we will advise on the preparation the study needs.
Q2: Do I need a developmental study, a reproduction study, or both?
A2: Product type, intended use and target market drive the decision. Most projects begin with a prenatal developmental toxicity study, and a reproduction study is added for long-term use products or at a regulator's request. Our team can propose a design that suits your regulatory pathway.
Q3: How much material should I prepare before shipping samples?
A3: Species, the number of dose groups, the dosing period and retained samples together determine the quantity. A multi-generation study needs far more material than a prenatal developmental study. Because the exact amount is fixed in the protocol before work starts, you have time to prepare enough.
Q4: When will I receive the final report?
A4: From animal acclimation to the final report, a prenatal developmental study generally takes a few months. Two-generation and extended one-generation studies run considerably longer, since the dosing period and required examinations also affect the timeline. The quotation confirms the full schedule.
Q5: How are adverse findings reported and interpreted?
A5: Dose levels at which effects appear are identified in the report, which also separates maternal toxicity from direct fetal effects and sets a no-observed-adverse-effect level where possible. You can then adjust the formulation or define safe use levels. We are happy to go through the findings and next steps with you in detail.
