ICSI sperm injection into oocyte. Oocyte cryopreservation (commonly referred to as OC or egg freezing) is a form of assisted reproductive technology (ART) used to preserve human eggs . The technique is often used to delay pregnancy. When pregnancy is desired, the eggs can be thawed, fertilized, and transferred to the uterus as embryos.
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]
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.
Egg donors are resources for women with no eggs due to surgery, chemotherapy, or genetic causes; or with poor egg quality, previously unsuccessful IVF cycles or advanced maternal age. In the egg donor process, eggs are retrieved from a donor's ovaries, fertilized in the laboratory with the sperm from the recipient's partner, and the resulting ...
There are a number of steps that are followed before a genetically modified organism (GMO) is created. Genetic engineers must first choose what gene they wish to insert, modify, or delete. The gene must then be isolated and incorporated, along with other genetic elements, into a suitable vector. This vector is then used to insert the gene into ...
A young woman, who planned to die under the Netherlands’ assisted dying laws, revealed she “changed [her] mind” at the very last minute and decided to live.“I don’t regret the journey.
A transvaginal oocyte retrieval is then performed at a time usually between 34 and 36 hours after hCG injection, that is, shortly before when the follicles would rupture. A retrieval at 36 hours after final maturation induction appears to result in optimal embryo quality and pregnancy outcomes. [ 9 ]
Ovulation is an important part of the menstrual cycle in female vertebrates where the egg cells are released from the ovaries as part of the ovarian cycle.In female humans ovulation typically occurs near the midpoint in the menstrual cycle and after the follicular phase.
