In vitro fertilisation (IVF) is a process of fertilisation 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.
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 transferred to a maternal uterus.
[1] Embryos which reach the day 3 cell stage can be tested for chromosomal or specific genetic defects prior to possible transfer by preimplantation genetic diagnosis (PGD). Embryo culture until the blastocyst stage confers a significant increase in live birth rate per embryo transfer , and there is no evidence of a difference between the ...
Assisted reproductive technology (ART) includes medical procedures used primarily to address infertility.This subject involves procedures such as in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), cryopreservation of gametes or embryos, and/or the use of fertility medication.
In vitro fertilization: once the egg is obtained it is fertilized with the donor sperm in a laboratory. [7] This can be done by ICSI technique or regular In vitro fertilization. Once the egg is fertilized, embryos are obtained that are kept in the lab for 3 to 5 days, when they develop to blastocysts. [ 8 ]
HFEA has estimated the live birth rate to be approximately 1.3% per IVF cycle using no hyperstimulation drugs for women aged between 40–42. [5] There is also a small risk of spontaneous ovulation before egg collection. As a consequence, there is a need for a much larger number of cycles before achieving a live birth on average, in turn ...
Veterans in the Inland Northwest seeking in vitro fertilization can be referred to the University of Washington Reproductive Care Clinic by the Mann-Grandstaff VA Medical Center in Spokane.
Chance of fertilization by menstrual cycle day relative to ovulation [15] Pregnancy rates for sexual intercourse are highest during the menstrual cycle time from some 5 days before until 1 to 2 days after ovulation. [16] For optimal pregnancy chance, there are recommendations of sexual intercourse every 1 or 2 days, [17] or every 2 or 3 days. [18]
