IVF for infertility
Infertility can be encountered when a couple faces problems deriving from the woman’s or the man’s reproductive system.
In vitro fertilization is a widely implemented procedure where woman’s eggs get fertilized by the sperm of her partner in an embryology laboratory. In several cases, donor egg or donor sperm may be used to deal with some particular infertility causes.
Causes leading to IVF
The main indications for an IVF procedure are:
- Obstructed fallopian tubes
- Low sperm counts
- Polycystic ovary syndrome (PCOS)
- Severe endometriosis
- Inherited disorders requiring thorough investigation (pre-implantation genetic diagnosis)
- Unexplained infertility for more than 6 months or one year, depending on couple’s age.
Most of women who chose to undergo IVF will have to be administrated hormones to produce more than one egg from their ovaries. In this way we are in position to control in a better way the production of oocytes (eggs) and collect them when time is adequate. We mainly use two types of hormonal preparations (GnRH agonist or GnRH antagonist).
Depending on the results of your exams you will receive a combination of injected GnRH agonist with ovary-stimulating hormone injections. After that you will be closely monitored for several days, to insure that your eggs growth as desired before egg retrieval.
Several blood tests (blood oestrogen levels, as well as ultrasound scanning) will be required to insure that your eggs are maturing in the follicles. The sperm are collected usually by masturbation on the day the eggs are also collected. In some particular cases, sperm may have been collected and frozen at an earlier time. IVF process may be modified, according the individualized needs of each couple.
After that, in vitro fertilization takes place and embryos are incubated under certain conditions for few days. At this point we have to select the best fertilized embryos to be transferred back in uterus (usually from 1 to 3 embryos), using an ultra thin flexible catheter that is inserted through the cervix. The rest of the embryos are cryopreserved, in order to be used for future attempts, if needed.
Two weeks later, a pregnancy test will confirm if the procedure has been successful or not. The success rate depends on the age of the couple, the leading cause of infertility, etc.
Frozen or fresh embryos are selected according the particularities of each case and donor eggs or donor sperm may be needed to increase the chances for a successful result.
In order to increase the chances of getting pregnant many women choose to transfer more than one embryo in their uterus. This decision increases the probability for multiple gestations, with all possible risks that we encounter in such cases. Thus the number of embryos to be transferred must be discussed with the IVF experts.
