In addition, we plan to explore expanded indications for the single or dual intrauterine directional delivery to instill therapeutic drugs for the treatment of ailments of the fallopian tubes, for which we have issued patents. 66 Table of Contents Factors Affecting Our Business There are a number of factors that have impacted, and we believe will continue to impact, our results of operations and growth.
Factors Affecting Our Business There are a number of factors that have impacted, and we believe will continue to impact, our results of operations and growth. These factors include: • Commencement and conduct of clinical trials for our product candidates .
In October 2022, we announced an updated study design for the pivotal trial, which will now focus on couples experiencing male factor infertility. This update reflects a revised strategy to address this underserved population experiencing infertility with a goal of facilitating accelerated enrollment.
In April 2021 we received an IDE approval from the FDA that allowed us to initiate a pivotal trial for the FemaSeed device. The first subject was enrolled in July 2021. In October 2022, we announced an updated study design for the pivotal trial to focus on couples experiencing male factor infertility, an underserved patient segment.

Research and development Research and development, or R&D, expense consist of engineering, product development, clinical, and regulatory expenses.
We expect cost of sales to increase in absolute terms as our revenue grows. Research and development Research and development, or R&D, expenses consist of engineering, product development, clinical, and regulatory expenses.
Our artificial insemination solution in development includes our proprietary FemaSeed product candidate for artificial insemination, which features single intrauterine directional delivery with sperm, offering significant advantages over existing artificial insemination solutions, including being the only approach that allows selective delivery of sperm locally and directly to the fallopian tube where conception occurs.
Our FDA-cleared artificial insemination solution features single intratubal sperm delivery directed to the selected fallopian tube, the natural site of conception, offering significant advantages over existing assisted reproductive approaches, including significant cost savings and reduction of safety risks.
