Intracytoplasmic sperm injection in the rat

Zygote, 1998
We applied intracytoplasmic sperm injection (ICSI) to the rat comparing three different sperm injection techniques: conventional setup with a sharp needle bearing a spike (method 1), combination of partial zona dissection (PZD) needle and blunt pipette (method 2) and piezo-injection using a blunt pipette (method 3).

Intracytoplasmic Sperm Injection in Mice

Cold Spring Harbor Protocols, 2018
Intracytoplasmic sperm injection (ICSI) is the injection of a single spermatozoon directly into the cytoplasm of an oocyte using an injection pipette. Spermatozoa that are used for ICSI do not need to be motile or alive. Indeed, for mouse ICSI, the sperm tail is typically broken off before injection into the oocyte, resulting essentially in a nuclear ...

Is Intracytoplasmic Sperm Injection Overused?

Journal of Urology, 2012
We determined whether the use of intracytoplasmic sperm injection in couples who previously underwent intracytoplasmic sperm injection cycles elsewhere could be decreased without compromising the pregnancy rate.At our university in vitro fertilization-embryo transfer center we retrospectively analyzed the records of 149 fresh, in vitro fertilization ...

Intracytoplasmic Sperm Injection

2007
As illustrated in this book, many medical and surgical options improve male factor infertility and permit couples to conceive naturally, or with minimal medical intervention. But there are still many conditions where sperm function will remain compromised and thus prevent the fertilization of an egg.

Intracytoplasmic sperm injection – an update

Reproductive Medicine Review, 2001
Infertility, a failure of conception after at least 12 months of unprotected intercourse, will affect 14–17% of couples at some time in their reproductive lives. The types of infertility, with their respective frequencies, are tubal and pelvic pathology (35%), male problems (35%), anovulation (15%), unexplained infertility (10%) and other infrequent ...

Safety of Intracytoplasmic Sperm Injection

2014
Early follow-up studies of IVF children showed that the frequency of birth anomalies resembled those arising with natural conception. More detailed analyses confirmed these findings, reinforcing the concept of the preimplantation period as teratologically "safe." The use of intracytoplasmic sperm injection (ICSI) to achieve fertilization introduced ...

In vitro fertilization by intracytoplasmic sperm injection

BioEssays, 1999
Intracytoplasmic sperm injection (ICSI) is the latest, and by far the most efficient, variant of micromanipulation-assisted fertilization, whereby a single spermatozoon is selected, aspirated into a microinjection needle and injected to the oocyte cytoplasm.
