IVF - In vitro Fertilization

IVF or In vitro Fertilization is a treatment that is offered to couples with unexplained fertility, endometriosis or the female has blocked or an absence of fallopian tubes. The female will be advised by one of the medical staff when in her cycle to start medication. All treatment centres use different drug protocols, the following example is a standard long cycle.

IVF Stage 1

The first stage of IVF treatment involves taking a nasal spray or subcutaneous injection of GnRH or Gonandotrophin releasing Hormone analogue. This drug temporarily stops the normal activity of the ovary so that ovulation does not occur when the ovaries are being stimulated. It shuts down the ‘normal’ ovarian function. Some women may experience side effects from the nasal spray or injection. These can be headaches, hot flushes or mood swings. The symptoms can be similar to that of PMT. The nasal spray or injection is taken for approximately two weeks. An ultra sound scan will then be performed to ensure that the ovaries are inactive.

IVF Stage 2

Following the scan and confirmation that the nasal spray or injection has worked, the second drug will be introduced. These are administered by subcutaneous injection. These drugs are known as FSH or Follicle Stimulating Hormones. These will be administered on a daily basis and a scan will be scheduled between Day 6-Day 9 to check the response. FSH stimulates the ovaries to produce multiple follicles. The progress will be assessed by ultra sound scans. There can also be some side effects with these drugs such as tiredness, feeling bloated or breast tenderness.
