Background
Background

  • Texas Tech Device for Improved Semen Collection (TTU-DISC)

  • Design of the device: limit surface area, concentrate the sample, and provided a buffering agent

  • The device was found to improve semen parameters in animal trials.

  • Estimated one in seven couples in U.S. have difficulties conceiving.

  • Twenty percent of the time infertility linked to female, 25% of the time infertility linked to the male, 55% of the time factors associated with both partners, or, unknown.

  • Three main issues with male associated infertility: 1. count, 2. motility, 3. morphology

  • Human trials comparing the ReproMaX to the standard collection containers will take place.

  • Samples will be collected and tested for: standard semen parameters, acrosome reactions, lipid peroxidation, evaluation of plasma and mitochondrial membranes, assessment of sperm chromatin structure, and biocompatibility trials.
