Cytoplasmic transfer in the mouse in conjunction with intracytoplasmic sperm injection

Piezo-actuated Mouse ICSI (Intracytoplasmic sperm injection)

Intracytoplasmic sperm injection (ICSI) is not only used in human assisted reproduction (ART), but it is also widely employed for veterinary in vitro fertilization during rare species preservation, germ-line rescue of transgenic animals or for any veterinary assisted conception. Piezo-assisted ICSI, which was first described in 1995 [1], can be employed for assisted conception in animals in whi...

Sperm-induced oocyte activation in the rhesus monkey: nuclear and cytoplasmic changes following intracytoplasmic sperm injection.

Intracytoplasmic sperm injection (ICSI) has increased the potential of the assisted reproductive technologies to propagate mammalian species and has provided an opportunity for research into cell cycle control and the mechanisms involved in sperm-induced oocyte activation. We have investigated the efficacy of ICSI in the rhesus monkey, the mechanism of fertilization following sperm injection an...

Intracytoplasmic Sperm Injection

Intracytoplasmic Sperm Injection (ICSI) is an assisted reproductive technique [4] (ART) initially developed by Dr. Gianpiero D. Palermo [5] in 1993 to treat male infertility [6]. It is most commonly used in conjunction with in vitro [7] fertilization [8] (IVF) or a less commonly used technique called zygote intrafallopian transfer [9] (ZIFT). In natural fertilization [8], the sperm [10] must pe...

Intracytoplasmic sperm injection (ICSI)

IVF has become a well-established treatment for certain types of infertility, including long-standing infertility due to tubal disease, endometriosis, unexplained infertility or infertility involving a male factor. Soon it became clear that certain couples with severe male-factor infertility could not be helped by conventional IVF. Extremely low sperm counts, impaired motility and/or abnormal m...
