The long protocol is where the ovary is shut down for three weeks following which oestrogen tablets or patches are started and are taken for 10 to 14 days. Then the expected due date is 9 months from this date. The last menstrual period is calculated by moving two weeks backward from that date. You then move back by 5 days and consider that to be the day when the sperm and the egg were injected or IVF was done. An easy way to detect due date is to note the day of a blastocyst transfer. There are specific IVF due date calculators which can be used. How Do You Work Out Your Due Date With IVF? If a frozen cycle is planned then after three weeks from the start of stimulation embryos are frozen and can be replaced after preparation which may take a further 6 to 8 weeks. In a further two weeks, the results would be available. If a fresh transfer is planned then in approximately three weeks the embryos are transferred inside the womb.

This includes daily injections and is followed by oocyte (egg) retrieval. The stimulation of the ovaries which includes daily injections usually takes between 10 and 15 days.

Frequently Asked Questions About The IVF Process How Long Does The IVF Process Take? ICSI is where a single mature egg is confirmed and injected with a single sperm. Fertilitzation can then be observed the next day. It is then left to nature to fertilise the eggs. In IVF, the eggs are mixed with washed and ready sperm in the laboratory.

Day 5 embryos can be transferred or frozen.

Blastocyst form on day 5, day 6 or sometimes on day 7 These embryos have differentiated into cells that form the baby and cells that form the placenta. The ideal time for freezing or for transfer is at a blastocyst stage (day five embryos which have accelerated in growth and have between 100-250 cells).

Embryos are then cultured and observed for three to five days.

In some cases, there may be low fertilisation or no fertilisation. Usually, between 50 and 60% of eggs are fertilised.

The day after the procedure is the fertilisation check.

Then the IVF or ICSI procedure is performed.

Some follicles will be empty while others will contain eggs. Follicles may be flushed to try and see if an egg is detected.

Each follicle is drained and checked if eggs are present or not.

A small needle is inserted into the hand and anaesthesia (deep sedation) is given.

On the day of egg collection, identity checks are conducted prior to the procedure itself.

You’ll also be asked to come in early in the morning fasting and be prepared for an anaesthetic. You would be asked to fast from midnight preceding the egg collection date without taking any fluids or food.The day after the trigger injection they are no injections and in some cases, a blood test is required.This trigger injection is either Suprecur (if freezing of eggs is being undertaken) or HCG (when a fresh transfer is planned). During these injections, three to four ultrasound scans are needed to assist in the progress and to plan the day when oocyte retrieval will take placeģ6 hours before the egg retrieval, a trigger injection is given.

In antagonist protocol on day five or day six of FSH stimulation an additional injection is added which blocks ovulation.

Ovarian stimulation with FSH injections, when the long protocol is used this is preceded by three weeks of downregulation injection.

There are many stages in the process of IVF and ICSI treatments IVF and ICSI are assisted conception treatments where the sperm and eggs are treated outside the body, eggs are fertilised in the laboratory and embryos are then transferred when the embryo reaches a blastocyst stage IVF & ICSI Process Stages
