Ovarian Ectopic Gestation after Assisted Reproductive Technique with Intracytoplasmic Sperm Insemination

Ectopic ovarian pregnancy after intracytoplasmic sperm injection with testicular spermatozoa - a case report

Ovarian ectopic pregnancy is a rare event in both natural and assisted human reproduction settings. There are few reports of this event after in vitro fertilization. Diagnosis can be challenging, since it requires specific medical expertise. Patients with this condition call for careful management during treatment so as to not affect their fertility potential. This paper describes the case of a...

Efficiency of laser-assisted intracytoplasmic sperm injection in a human assisted reproductive techniques program

OBJECTIVE Laser-assisted intracytoplasmic sperm injection (LA-ICSI), also known as micro-opening or thinning of the zona pellucida (ZP) prior to ICSI, may help to reduce mechanical damage to the oocyte during the procedure. The aim of the present study was to evaluate and analyze the efficacy of our institutional LA-ICSI program, which features laser-assisted ZP thinning prior to ICSI, in compa...

Freeze-dried primate sperm retains early reproductive potential after intracytoplasmic sperm injection.

Oocytes inseminated by intracytoplasmic sperm injection using fresh ejaculated or freeze-dried rhesus macaque sperm showed similar activation, sperm aster assembly, and male-female pronuclear apposition rates.

Cervical Ectopic Pregnancy following Assisted Reproductive Technology: A Case Report

Failed fertilization after clinical intracytoplasmic sperm injection.

Intracytoplasmic sperm injection (ICSI) has resulted in pregnancy and birth for many couples, including those with severe male factor infertility. However, even after ICSI, complete failure of fertilization occurs in 1-3% of cycles. Most cases occur due to low number of mature oocytes, failure of oocyte activation or non-availability of appropriate spermatozoa for injection. Given the significa...
