Frequently Asked Questions
ICSI (Intracytoplasmic Sperm Injection) is a laboratory fertilization technique used as part of an IVF treatment cycle. During ICSI, an embryologist selects a single sperm and injects it directly into an egg to facilitate fertilization. In conventional IVF, eggs and sperm are placed together in the laboratory and fertilization occurs without direct sperm injection.
ICSI may be considered for patients with significant male-factor infertility, very low
sperm counts or poor sperm motility, previous fertilization problems, or certain cases where sperm needs to be retrieved surgically. Your fertility specialist will assess your individual circumstances before recommending the most appropriate treatment approach.
In some cases, sperm may be retrieved directly from the epididymis or testicles using procedures such as PESA, TESA or TESE. If suitable sperm is retrieved, it may be used for ICSI depending on the individual circumstances and medical assessment.
An ICSI cycle generally includes ovarian stimulation, follicle monitoring, a trigger injection, egg retrieval and sperm collection. In the laboratory, a single sperm is injected directly into each suitable mature egg. The resulting embryos are then monitored as they develop, and embryo transfer is planned according to the individual treatment plan.
No. ICSI is designed to assist the fertilization process, but it cannot guarantee that every egg will fertilize or that an embryo will implant and result in a pregnancy. Treatment outcomes depend on several factors, including egg and sperm characteristics, embryo development and individual patient circumstances.
