Reproductive Techniques, Assisted Categories.
 |
Embryo Transfer - The transfer of mammalian embryos from an in vivo or in vitro environment to a suitable host to improve pregnancy or gestational outcome in human or animal. In human fertility treatment programs, preimplantation embryos ranging from the 4-cell stage to the blastocyst stage are transferred to the uterine cavity between 3-5 days after FERTILIZATION IN VITRO. |
|
Fertilization in Vitro - An assisted reproductive technique that includes the direct handling and manipulation of oocytes and sperm to achieve fertilization in vitro. |
|
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. |
|
Oocyte Donation - 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. |
|
Ovulation Induction - Techniques for the artifical induction of ovulation, the rupture of the follicle and release of the ovum. |
|
Posthumous Conception - Conception after the death of the male or female biological parent through techniques such as the use of gametes that have been stored during his or her lifetime or that were collected immediately after his or her death. |
|
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). |
