Human Sperm Survival Assay (HSSA)
Ensuring Product Compatibility and Reproductive Safety
The Human Sperm Survival Assay is an in vitro test used to assess the effect of materials, devices, or media on sperm motility and viability over time. It is an essential bioassay for verifying the biocompatibility and safety of products used in reproductive applications such as IVF culture media, catheters, and medical-grade plastics.
In this assay, motile sperm are incubated with the test sample under controlled laboratory conditions, and motility is measured at defined intervals (typically 24–48 hours). Any reduction in motility compared to control samples indicates potential cytotoxic or spermicidal effects.
Sperm Motility Index (SMI) Assay
Quantitative motility - strength assessment for experimental and comparative studies (Not for clinical diagnostic use)
The Sperm Motility Index (SMI) Assay provides a consolidated quantitative score representing overall sperm movement quality, efficiency, and functional motility. The index integrates key motility parameters into a single value, enabling simplified comparison across samples, treatments, time points, or experimental conditions.
The SMI is particularly useful in research settings where a standardized motility performance metric is required to compare media conditions, drug effects, cryopreservation protocols, toxicology exposure, or experimental treatments affecting sperm function.
Sperm Lubricant Biocompatibility Assessment
Evaluation of how personal lubricants, gels, or related products affect sperm quality under controlled laboratory conditions
The Sperm Lubricant Biocompatibility Assessment evaluates how different lubricants influence sperm viability, motility, and functional performance in a research environment. This service is designed to help researchers understand the compatibility of various formulations with human sperm and to determine whether certain products preserve, impair, or alter functional parameters.
The assay is frequently used in reproductive research, product development, toxicology studies, and formulation optimization for fertility-friendly lubricants.
Lubricant Barrier Assay
Evaluation of the physical and functional barrier properties of personal lubricants in relation to sperm movement and penetration
The Lubricant Barrier Assay examines how a lubricant’s physical characteristics such as viscosity, consistency, structural spread, and film formation affect the ability of sperm to move through or interact with it under controlled research conditions. This assay focuses on the barrier effect of lubricants rather than cellular toxicity, assessing whether the lubricant forms a physical obstruction that alters movement patterns or restricts forward progression.
This service is commonly used in studies related to reproductive safety testing, formulation development, evaluation of product effects on sperm transport, and research on mechanical obstacles in sperm microenvironments.
Cytotoxicity Testing
Evaluating Biological Safety and Cellular Response
Our Cytotoxicity Testing service assesses the potential toxic effects of materials, devices, or compounds on cultured cells. It is a critical step in determining the biocompatibility and safety of medical products used in reproductive and clinical applications.
Using standardized in vitro assays, Spermatica Laboratories measures cell viability, morphology, and metabolic activity following exposure to test samples. Any reduction in these parameters indicates potential cytotoxic effects.
Reproductive Biology Analysis
Comprehensive Testing for Fertility and Toxicology Research
Spermatica Laboratories offers a suite of reproductive biology assays tailored to evaluate gamete function, media performance, and toxicological impact in both research and product validation contexts.
Our customized analyses help clients study fertility parameters, cellular integrity, and product compatibility, enabling a deeper understanding of reproductive outcomes.
