2. Sample Size Used for the Test Set and Data Provenance

Sample Size: Not explicitly stated. The document mentions "a sperm recovery assay" that will be performed, but not the sample size for this assay or for the "variety of clinical settings" where the products were used.
Data Provenance: The document refers to "historical information contained in professional literature" and "used in a variety of clinical settings, for their intended use for a number of years." This suggests the data is retrospective, gathered over time from clinical use, rather than from a dedicated prospective study for this 510(k) submission. No specific country of origin is mentioned, but "clinical settings" implies real-world use.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Those Experts

This document does not describe the use of experts to establish a "ground truth" for a specific test set in the modern sense of algorithm evaluation. The assessment relies on the product's historical clinical use and a standard laboratory assay (sperm recovery).

4. Adjudication Method for the Test Set

Not applicable. There's no mention of a human expert adjudication process for a test set. The evaluation is based on product performance in clinical use and laboratory assays.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done, If So, What Was the Effect Size of How Much Human Readers Improve with AI vs Without AI Assistance

Not applicable. This is a submission for a reproductive media product, not an AI or imaging device that would involve human readers or AI assistance.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

Not applicable. This is not an algorithmic device. The "performance data" refers to the biological function of the media.

7. The Type of Ground Truth Used

The "ground truth" for the performance of these media is established by the biological outcome of sperm viability and recovery after exposure to the medium, as measured by a "sperm recovery assay," and indirectly by their successful use in "clinical settings" over time leading to them becoming "standard media." It also relies on compliance with a regulatory standard (Notice of Final Rule, 63 FR 48428).

8. The Sample Size for the Training Set

Not applicable. This is not a machine learning or AI device that requires a training set.

9. How the Ground Truth for the Training Set Was Established

Not applicable. There is no training set for this device.

April 20, 1999

Intended Use:

TYB Freezing Medium with Glycerol is intended for the cryopreservation of human semen samples prior to use in assisted reproductive technology procedures. TYB Refrigeration Medium is intended to protect human semen samples during refrigerated storage prior to use in assisted reproductive technology procedures.

Technological Characteristics:

TYB Freezing Medium with Glycerol and TYB Refrigeration Medium have utility for those situations where semen must be stored prior to use in assisted reproductive procedures such intrauterine insemination, in vitro fertilization or intracytoplasmic sperm injection (ICSI). TYB Freezing Medium with Glycerol is designed to protect semen samples during frozen storage, while TYB Refrigeration Medium is designed to protect semen samples during refrigerated storage.

Performance Data:

TYB Refrigeration Medium and TYB Freezing Medium with Glycerol will be assayed by a sperm recovery assay prior to release to market. The assay will ensure that the product functions appropriately and that no toxic components are present in the formulation. TYB Refrigeration Medium and TYB Freezing Medium with Glycerol have been used in a variety of clinical settings, for their intended use for a number of years. In that time, the products have become the standard media used for the low temperature storage and preservation of human semen samples.

Additional Information:

A sperm recovery assay will be performed as a condition of release for these products, as well as endotoxin and sterility testing. Results of all release assays performed will be reported on a lot-specific certificate of analysis, and will be indicated on the labeling.
