Abstract The purpose of this study is to develop a novel method for the cryopreservation and efficient post-thaw recovery of individual or small numbers of human spermatozoa. Spermatozoa equilibrated in cryoprotectant bu
Objective: To develop an efficient cryopreservation method using a single sperm. Design: Experimental study. Setting: Laboratory of a private institute. Patient(s): A fertile donor. Intervention(s): We produced hollow-co
Abstract. Herein, we report the birth of two healthy babies to a woman following intracytoplasmic sperm injection (ICSI) using motile spermatozoa vitrified without permeable cryoprotectants. Spermatozoa (in a case of oli
Abstract Cryopreservation of human spermatozoa free from cryoprotectant can avoid toxicity caused by highly concentrated cryoprotectant and a series of specific carriers have been previously explored, except for PDMS chi
