Intracytoplasmic sperm injection (ICSI)
Intracytoplasmic sperm injection (ICSI) is a form of IVF in which a single sperm is injected directly into an egg. This process is used in cases of male infertility.
As with ordinary IVF, the female partner takes fertility drugs to stimulate the production of several mature eggs, which are surgically removed. At the same time, sperm are collected from the male partner. In some cases, sperm are collected directly from the testicles by means of a fine-needle biopsy procedure.
Active sperm are chosen, and a single sperm is injected into an egg in a laboratory. After about 24 hours, a fertilized egg should have begun to divide and grow. On day 3, one or two fertilized eggs are transferred to the female partner’s uterus. Other fertilized eggs can be frozen for later use.
<< STEP I: Injection needle after collecting a single sperm from a testicular biopsy procedure.
<< STEP 2: Injecting the single sperm into the cytoplasm of an egg using a glass needle.
<< STEP 3: Pronuclei merge into one normal component of chromosomes. The ICSI procedure results in an average fertilization rate of 66%.
<< STEP 4: On day three the embryos
are transferred to the uterus. Thanks to ultrasound, the embryos can be
correctly placed in the endometrial cavity.Our embryologist may suggest waiting until Day 5 to transfer the embryos (Blastocyst option) which reduces the chance of triplets and increases pregnancy rate.
