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.
Repeated implantation failure (RIF) is the repeated failure of the embryo to implant onto the side of the uterus wall following IVF treatment. [1] Implantation happens at 6–7 days after conception and involves the embedding of the growing embryo into the mothers uterus and a connection being formed. [ 2 ]
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. [13]
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 ...
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
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 ...
Autoimmune disorders can lead to complications in implantation of the egg in the uterus, which may be the immune system's attack response to an established embryo on the uterine wall. [35] Cancer ultimately affects fertility and may lead to birth defects or miscarriages. Cancer severely damages reproductive organs, which affects fertility.
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 ...
