Gamete Intrafallopian Transfer
A technique that came into use in the mid-1980's for assisted conception in infertile women with normal fallopian tubes. The protocol consists of hormonal stimulation of the ovaries, followed by laparoscopic follicular aspiration of oocytes, and then the transfer of sperm and oocytes by catheterization into the fallopian tubes.
Transfer of preovulatory oocytes from donor to a suitable host. Oocytes are collected, fertilized in vitro, and transferred to a host that can be human or animal.
Female germ cells derived from OOGONIA and termed OOCYTES when they enter MEIOSIS. The primary oocytes begin meiosis but are arrested at the diplotene state until OVULATION at PUBERTY to give rise to haploid secondary oocytes or ova (OVUM).
A type of chromosome aberration characterized by CHROMOSOME BREAKAGE and transfer of the broken-off portion to another location, often to a different chromosome.
Zygote Intrafallopian Transfer
A technique in assisted reproduction (REPRODUCTIVE TECHNIQUES, ASSISTED) consisting of hormonal stimulation of the ovaries, follicular aspiration of preovulatory oocytes, in-vitro fertilization, and intrafallopian transfer of zygotes at the pronuclear stage (before cleavage).
The aim of the study was to evaluate the efficacy of melatonin administration on oocyte quality in women underwent in vitro fertilization (IVF) cycles. Eighty-five women undergoing IVF cycles were ran...
The objective of this study is to compare the pregnancy and live birth rates of a natural cycle in vitro fertilization (IVF) combined with in vitro maturation (IVM) treatment (natural cycle IVF/M) by...
Oocyte quality is one of the most important aspects of in vitro embryo development. Extensive epigenetic programming must occur during oocyte growth and maturation. A specific DNA methylation pattern...
SummaryWhale oocytes recovered from follicles can be matured in vitro. Whale sperm and mature oocytes can be used for in vitro fertilization (IVF), and IVF embryos have the ability to develop to morul...
PURPOSE: The cryopreservation of immature oocytes permits oocyte banking for patients at risk of losing their fertility. However, the optimum protocol for such fertility preserva...
The aim of this study is to aspirate immature oocytes from antral follicles and mature the oocytes in vitro. These mature oocytes will serve for fertilization and the creation of embryos w...
Retrieval of immature oocytes from women with polycystic ovaries, their in-vitro maturation, fertilization and embryo transfer can prevent hormonal treatment that can lead to ovarian hyper...
The objective of this study is to evaluate the efficacy of embryo transfer procedure guided by transvaginal ultrasound versus abdominal ultrasound in recipients of oocytes as well as the a...
Various morphological abnormalities of human oocytes were reported to detrimentally affect embryo development. We observed development of frozen thawed embryos derived from oocytes with no...
There is a considerable concern about the effects of controlled ovarian hyperstimulation (COH) for In Vitro Fertilization- Embryo Transfer (IVF-ET) on embryo quality and on the incidence o...
