AI Technical Summary
Technical Problem
Existing sperm measurement systems fail to evaluate the fertilization ability of spermatozoa based on factors other than sperm concentration, leading to insufficient evaluation accuracy.
Method used
A system and method that detects the short-axis line image in sperm head images to generate fertilization ability information, using an imaging unit to capture sperm head images and an image processing device to analyze and output this information, which includes a short-axis image detection unit and a fertilization ability information generation unit.
Benefits of technology
Improves the accuracy of evaluating sperm fertilization ability by quantitatively assessing the presence and ratio of short-axis images, providing objective indicators of fertilization capacity.

Abstract
Provided are: a fertility information generation system, a fertility information generation method, and a fertility information generation computer program that can improve the accuracy of sperm fertility evaluation. This fertility information generation system 100 comprises: a short axis line image detection unit 124 that detects a short axis line image 210, composed of two substantially parallel lines or a single belt-like line extending in the short axis direction of a head part of a spermatozoon 90, in a sperm head part image 200 obtained by capturing an image of at least the head part of the spermatozoon 90; a fertility information generation unit 125 that generates fertility information usable for fertility evaluation on the basis of the results of the detection of the short axis line image 210 performed by the short axis line image detection unit 124; and a storage unit 123 and a display device 122 that store or output the fertility information generated by the fertility information generation unit 125.
