Abstract: Intracytoplasmic sperm injection (ICSI) has been widely used for generating offspring in human infertility clinics and in reproductive researched on mice. Many researchers engaged in animal transgenesis still consider it somewhat cumbersome. However, the greatest advantage of ICSI-mediated transgenesis is that it allows introduction of very large DNA transgenes (e.g., yeast artificial chromosomes), with relatively high efficiency into the genomes of hosts, as compared to pronuclear injection. Recently, researchers have developed an active form of intracytoplasmic sperm injection-mediated transgenesis (ICSI-Tr) with fresh sperm utilizing transposons. The transgenic efficiencies rival all transgenic techniques except that of lentiviral methods so that it is worthy of promotion and application in animal transgenic research.
