Intracytoplasmic sperm injection (ICSI / ˈ ɪ k s i / IK-see) is an in vitro fertilization (IVF) procedure in which a single sperm cell is injected directly into the cytoplasm of an egg. This technique is used in order to prepare the gametes for the obtention of embryos that may be transferred to a maternal uterus.
Spermatozoa can be considered morphologically suitable for ICSI procedures when the sperm head is a regular oval, symmetric and has a smooth appearance. It should be 4.5–4.9 μm in length and 3.1–3.5 μm in width.
Assisted reproductive technology (ART) includes medical procedures used primarily to address infertility.This subject involves procedures such as in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), and cryopreservation of gametes and embryos, and the use of fertility medication.
The ICSI procedure is carried out on mature metaphase-II oocytes and fertilization is assessed 16–18 hours after. The embryo development is further evaluated every day prior to biopsy and until transfer to the woman's uterus.
Testicular sperm extraction (TESE) is a surgical procedure in which a small portion of tissue is removed from the testicle and any viable sperm cells from that tissue are extracted for use in further procedures, most commonly intracytoplasmic sperm injection (ICSI) as part of in vitro fertilisation (IVF).

There is gestational surrogacy [a procedure where a woman carries and gives birth to a baby for another person or couple but is not genetically related to the baby] and traditional surrogacy [a ...
Thus, when eggs are thawed and pregnancy is desired, a fertilization procedure known as intracytoplasmic sperm injection (ICSI) is performed by an embryologist whereby sperm is injected directly into the egg with a needle rather than allowing sperm to penetrate naturally by placing it around the egg in a dish.
Transvaginal oocyte retrieval (TVOR), also referred to as oocyte retrieval (OCR), is a technique used in in vitro fertilization (IVF) in order to remove oocytes from an ovary, enabling fertilization outside the body. [1]
