Intracytoplasmic sperm injection

Molecular and Cellular Endocrinology, 2002
Intracytoplasmic sperm injection (ICSI) with ejaculated, epididymal or testicular spermatozoa was first successful in 1992 and has since become the widely accepted treatment for couples with severe male-factor infertility. The outcome of several thousands of ICSI cycles in terms of fertilization, embryo cleavage and implantation is similar to that for ...

Intracytoplasmic sperm injection in the mouse*

Human Reproduction, 1995
Intracytoplasmic sperm injection (ICSI) into mouse oocytes involves a very low survival rate. This study was designed to determine why ICSI frequently fails in mice. Metaphase II oocytes were obtained from superovulated 4-6 week old F1 hybrid mice. Spermatozoa were retrieved from the epididymis of 12-14 week old F1 hybrid mice.

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 ...

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 – 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 ...

Intracytoplasmic sperm injection (ICSI)

Fertility and Sterility, 2008
Intracytoplasmic sperm injection (ICSI) is a component of in vitro fertilization (IVF), a standard clinical technique for many years, and is no longer considered experimental. ICSI has dramatically increased the ability of males previously considered infertile to father children.

Intracytoplasmic Sperm Injection

The Journal of Urology, 1996
We evaluated the efficacy of intracytoplasmic sperm injection in patients with extreme oligospermia.A total of 67 intracytoplasmic sperm injection cycles was attempted in 58 infertile couples in which the husbands had extreme oligospermia (less than 100,000 spermatozoa per ml. ejaculate).Fertilization was achieved in 65 of 67 cycles. Mean fertilization

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 ...

Intracytoplasmic Sperm Injection

2019
The main indication is severely impaired sperm parameters, severe oligozoospermia, severe asthenozoospermia, and severe teratozoospermia. Intracytoplasmic sperm injection (ICSI) has enabled clinicians to reach the same fertilization rates reached with in vitro fertilization (IVF) in cases without severe male factor parameters. According to the protocol
