Pre-Programme Preparations

Blood tests have to be performed to exclude venereal diseases such as syphilis, HIV, Hep B and AIDS. A rubella antibody test will also be carried out. You will be advised to have a rubella vaccination before the IVF procedure if you have no immunity against it. Your husband will have a pre-IVF semen analysis to determine any need for the sperms to be frozen and stored. The wife should also start taking folate daily.

IVF ICSI Prgramme IVF programmes utilise Controlled Ovarian Hyperstimulation which results in more eggs and hence a better chance of pregnancy. Controlled Ovarian Hyperstimulation is carried out with GnRHa (e.g. Lucrin) and gonadotrophins (e.g. Gonal F or Puregon) injections. Various protocols are used. The protocol using GnRHa and gonadotrophins is described here:

1. Controlled Ovarian Hyperstimulation and Monitoring

a. GnRHa Injection

GnRHa treatment is given daily to prevent a spontaneous ovulation and to ensure that the ovarian follicles grow in synchronous fashion. It usually starts in the second half of your menstrual cycle and continues for about 14 to 20 days. Some patients may need to take this medication for longer periods.

Blood tests and ultrasound scans will be done to ensure that the optimum response is reached. Once this is achieved, you will proceed to the gonadotrophin injections.

b. Gonadotrophin Injection

Gonadotrophin is injected daily into the muscle/subcutaneous tissue of your thigh or buttock to stimulate the growth of the follicles in the ovaries. After several days of gonadotrophin injections, an ultrasound scan is performed to determine the number and size of the growing follicles. You will need additional injections if the follicles have not reached the desired size.

When the follicles have reached the desired size, an injection of HCG is given and GnRHa and gonadotrophin are discontinued. The HCG is required for the final maturation of eggs before the egg collection. The egg collection is scheduled about 36 hours after the HCG injection.

2. Sperm Preparation

During the gonadotrophin injections, your husband need not abstain from sexual intercourse before the egg collection. On the day of the egg collection, your husband needs to produce a fresh masturbated semen sample.

3. Egg Collection (Oocyte Pick Up)

The egg collection is performed at KKIVF. The eggs are collected through a special needle attached to an ultrasound vaginal probe. A mild sedative will be given to you, as only minimal discomfort will be experienced during the procedure.

After the egg collection, you will be observed for a few hours before going home. It is important to understand that not all follicles will necessarily contain an egg and that some of the eggs may not be ripe enough for fertilisation. An overnight fast is required before oocyte pick-up procedures.

4A. Fertilization

The sperm is added to the collected eggs in a dish to allow fertilisation to occur by natural selection in the laboratory. A check to confirm that fertilisation has occurred is carried out the following day.

Unfortunately, in about 10% of couples, there is no fertilisation at all.

4B. Intra-Cytoplasmic Sperm Injection

ICSI will be performed on the day of oocyte pick-up. During the procedure, a single sperm will be injected into each egg via a microneedle. On the following day, a check is made to confirm that fertilisation has occurred.

5. Embryo Transfer

A few days after the egg collection, you will need to return to KKIVF to have the embryos placed into your uterus. An overnight fast is recommended before the embryo transfer procedure.

Embryos are re-placed into the uterus using a fine catheter. This is usually painless and takes only a few minutes. Usually, two or three embryos are transferred. A smaller number may be transferred if there are insufficient embryos or in younger patients. We encourage your husband to sit in during the embryo transfer.

You may go home shortly after the embryo transfer. You will be given daily hormonal support (progesterone or HCG) to support the lining of the uterus and to enhance the chances of the embryos implanting.

There is no restriction on activities including sexual intercourse.

6. Freezing of Extra Embryos

A proportion of patients may have excess good quality embryos. These may be frozen for future use. Patients do not need to undergo Controlled Ovarian Hyperstimulation and egg collection again for these future thaw cycles.

There is an annual storage fee for these frozen embryos.

7. Pregnancy

You will need to come to KKIVF/ SGH Centre for Assisted Reproduction (CARE) 17 days after the embryo transfer for a pregnancy test. You should call KKIVF/ SGH CARE if you are menstruating so that further instructions can be given.

If you are pregnant, subsequent ultrasound scans and blood tests will be arranged to ensure that the pregnancy is proceeding normally.

8. Useful Information

Success rates (KKIVF rates)

Our overall clinical pregnancy rate is about 40-44% per cycle and the take-home-baby rate is about 30%.

Generally, patients who are below 36 years old have a better pregnancy chance. However, your chances of success will depend very much on your own individual circumstances.

Success rates (SGH Centre for Assisted Reproduction)

CARE reached an average of 41% pregnancy rate for fresh IVF cycles and 38% for frozen cycles in 2018, in comparison to the global average of IVF pregnancy results in 2018 of 36% for Europe.
