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]
The process of somatic cell nuclear transfer involves two different cells. The first being a female gamete, known as the ovum (egg/oocyte). In human SCNT experiments, these eggs are obtained through consenting donors, utilizing ovarian stimulation. The second being a somatic cell, referring to the cells of the human body.
In a 2013 meta-analysis of more than 2,200 cycles using frozen eggs, scientists found the probability of having a live birth after three cycles was 31.5% for women who froze their eggs at age 25, 25.9% at age 30, 19.3% at age 35, and 14.8% at age 40.
Activated clotting time (ACT), also known as activated coagulation time, is a test of coagulation. [1] [2]The ACT test can be used to monitor anticoagulation effects, such as from high-dose heparin before, during, and shortly after procedures that require intense anticoagulant administration, such as cardiac bypass, interventional cardiology, thrombolysis, extra-corporeal membrane oxygenation ...
The main methods of fertility preservation are ovarian protection by GnRH agonists, cryopreservation of ovarian tissue, eggs or sperm, or of embryos after in vitro fertilization. [16] The patient may also choose to use egg or sperm from a donor by third party reproduction rather than having biological children.
To reduce the risk of intraamniotic infection, antibiotics are supplied through the intravenous access about 30–60 minutes before the procedure. If movement of the fetus is a risk to the success of the procedure, the fetus may be paralyzed using a fetal paralytic drug. [10] This image shows anterior blood sampling from the umbilical cord.
They suit to diagnose the general state of the blood coagulation system and the intensity of pathologies, and to simultaneously record all attendant influences. Global methods play the key role at the first stage of diagnostics: they provide an integral picture of alterations within the coagulation system and allow predicting a tendency to ...
In norma-ovulatory women, the success rate of IVM is lower than conventional ovarian stimulation regimens with poorer implantation and pregnancy rates. IVM is suboptimal and influenced by several factors. However, IVM is a milder approach to assisted reproduction treatment and an alternative procedure for specific conditions.
