Assisted reproductive technology
Assisted reproductive technology (ART) is any fertility treatment in which the egg and s***m are handled. There are several types of ART.
In vitro fertilization (IVF) is the most common ART technique. IVF involves stimulating and retrieving multiple mature eggs, fertilizing them with s***m in a dish in a lab, and implanting the embryos in the uterus several days after fertilization.
The indications include:
• Blocked /damaged Fallopian tubes, Inoperable tubes or where the tubes have been removed due to ectopic pregnancy.
• Endometriosis
• Mild- Moderate Male factor infertility.
• Unexplained infertility.
Other techniques are sometimes used in an IVF cycle, such as:
• Intracytoplasmic s***m injection (ICSI). A single healthy s***m is injected directly into a mature egg. ICSI is often used when there is poor semen quality or quantity, or if fertilization attempts during prior IVF cycles failed.
It is indicated in:
• Couples who have failed to achieve fertilization or poor fertilization after conventional IVF treatment.
• Men with abnormal s***m parameters.
• Azoos***mic men.
• Assisted hatching. This technique assists the implantation of the embryo into the lining of the uterus by opening the outer covering of the embryo (hatching).
• Donor eggs or s***m. Most ART is done using a couple's own eggs and s***m. However, if there are severe problems with either the eggs or the s***m, you may choose to use eggs, s***m or embryos from a known or anonymous donor.
• Gestational carrier. Women who don't have a functional uterus or for whom pregnancy poses a serious health risk might choose IVF using a gestational carrier. In this case, the couple's embryo is placed in the uterus of the carrier for pregnancy.
