In Vitro Fertilisation (incomplete)

Question 1

What is IVF?

Answer 1

In vitro fertilisation involves fertilising an egg with sperm in a lab, then injecting the resulting embryo into the uterus.

Question 2

Success rate of IVF?

Answer 2

Each attempt has a roughly 25 – 30% success rate at producing a live birth.

Question 3

Difference between intrauterine insemination and IVF?

When is it used?

Answer 3

Intrauterine insemination (IUI) is different from IVF. It is a more straightforward process, and involves injecting sperm into the uterus, avoiding intercourse.

IUI is used in cases such as donor sperm for same-sex couples, HIV (avoiding unprotected sex) and practical issues with vaginal sex.

Question 4

How many embryos are transferred in IVF?

Answer 4

A cycle of IVF involves a single episode of ovarian stimulation and collection of oocytes (eggs). A single cycle may produce several embryos. Each of these embryos can be transferred separately in multiple attempts at pregnancy, all during one “cycle” of IVF. Embryos that are not used immediately may be frozen to be used at a later date. Frozen embryos can potentially be used years later, even after a successful pregnancy.

Question 5

What are the steps involved in the process of IVF?

Answer 5

Suppressing the natural menstrual cycle
Ovarian stimulation
Oocyte collection
Insemination / intracytoplasmic sperm injection (ICSI)
Embryo culture
Embryo transfer
