In terms of outcome, "pregnancy" may refer to a positive pregnancy test, evidence of a pregnancy with a "viable" fetus or implantation. Furthermore, pregnancy rates can be influenced in IVF by transferring multiple embryos that may result in multiple births. A strict definition in the IVF setting would refer to the singleton pregnancy rate that ...
In vitro fertilization (IVF) is a process of fertilization in which an egg is combined with sperm in vitro ("in glass"). The process involves monitoring and stimulating a woman's ovulatory process, then removing an ovum or ova (egg or eggs) from her ovaries and enabling a man's sperm to fertilise them in a culture medium in a laboratory.
The benefits of using morphokinetics in terms of improving clinical outcomes of IVF is still very unclear. [9] A meta-analysis published in 2017, supported the idea of clinical benefits of time-lapse culture with morphokinetic embryo selection in IVF, reporting reduced early pregnancy loss, higher ongoing pregnancy and higher live birth rates.

The endocannabinoid system plays a vital role in this synchrony in the uterus, influencing uterine receptivity, and embryo implantation. [5] The embryo expresses cannabinoid receptors early in its development that are responsive to anandamide (AEA) secreted in the uterus. AEA is produced at higher levels before implantation and is then down ...
The success rate of reciprocal IVF heavily depends on the age of the birth mother. For women under age 35, there is a 41-43% success rate. For women over 40, there is a 13-18% success rate. [21] As IVF is not always successful on the first attempt, it is important that couples understand that multiple cycles may be required to achieve a ...
Freezing embryos for IVF became standard practice after the development of vitrification, a fast-freezing process that is safer for the embryo. While there’s still a risk of damage during the ...
On July 25, 1978, the world's first "test tube baby" was born. Louise Brown was the first person conceived through in vitro fertilization (IVF) and her birth eventually led to one of her doctors ...
A recent clinical trial showed a sharp reduction in miscarriage with embryos derived from PICSI sperm selection. [23] 'Washed' or 'unwashed' sperm may be used in the process. Live birth rate are significantly higher with progesterone to assist implantation in ICSI cycles. [24] Also, addition of a GNRH agonist has been estimated to increase ...
