Document Type and Number:
WIPO Patent Application WO/2021/190644
Kind Code:
A1
Abstract:
A method for screening a sperm during artificial insemination, comprising: step 1, arranging a culture solution on a transparent material; step 2: arranging an ovum at a designated position, and arranging the transparent material under a microscope; and step 3: arranging the sperm on the other end of the transparent material, and performing observation until the artificial insemination is completed. The method can increase the screening of the sperm at least to a certain extent, and can avoid the phenomenon of polyspermy at least to a certain extent. One feature of the present invention is transforming the difficulty of insemination by extending the distance between the ovum and the sperm and adjusting the viscosity of the culture solution. The present invention can also be used for replacing other artificial insemination plans during surrogacy.
