![]() ![]() The vitrification process prevents the formation of damaging ice crystals, and 97% of embryos survive the process. The truth is that frozen embryo transfer is just as successful as using fresh embryos for IVF, and we at IVI have conducted studies that have proven this. After this, the remaining good quality embryos are vitrified so that if necessary they can be used in a later cycle without the need for further ovarian stimulation.Īt this point, we should address the myth that frozen embryo transfers are not as successful as ‘fresh’ embryos. The resulting embryos are observed in the laboratory, the most viable selected, and inserted into the patient’s uterus in a quick and painless procedure. ![]() The ova are then fertilised either with conventional IVF or by means of ICSI. 36 hours later, follicular puncture, in which the follicles are retrieved, takes place. When the follicles have reached an adequate size and a suitable number of oocytes is present, a hormone injection causes the follicles to mature as they would in a natural cycle. Ultrasound scans are undertaken during the process to check that the follicles are developing. It starts with ovarian stimulation consisting of the administration of daily injections which cause the ovaries, instead of producing a single ovum which is what they do naturally each month, to produce more oocytes so that a larger number of embryos can be obtained. In all our IVI clinics, if IVF is the recommended treatment in an individual case of infertility, the process is as follows: The selected sperm is then injected directly into the ovum to increase the likelihood of conception taking place.įor a step-by-step explanation of how the IVF process works, you may find the IVI YouTube video at IVI/In Vitro Fertilisation a helpful exposition. This is a process whereby the best spermatozoa are selected from a semen sample or if necessary via testicular biopsy. This development has extended the standard IVF definition. Where severe male factor infertility is involved, a refinement of IVF that may be recommended is a technique called Intracytoplasmic Sperm Injection (ICSI). It is also recommended when a limited number of oocytes is available and in cases of severe male infertility. This option is recommended for patients for whom previous simpler treatments such as artificial insemination have failed for women with various problems with their fallopian tubes and for women suffering from advanced endometriosis. This process was originally, and sometimes still is, carried out using the conventional IVF process, which involves placing an oocyte surrounded by spermatozoa in a culture plate and allowing the two to combine so that conception can take place. In a nutshell, an IVF definition refers to the process of putting together the ovum and the spermatozoon in the laboratory – that is in vitro – in order to obtain fertilised embryos for transfer to the patient’s uterus. These days IVF is one of those subjects we all think we know something about, picked up from an article or a friend of a friend… But how much do you really know, and can you differentiate the facts about In Vitro Fertilisation (IVF) treatment from the urban myths? In this article we take a look at the IVF definition, what exactly happens in the IVF process, the facts about multiple births and some of the other hot topics around the subject: IVF success rates, and how much does IVF cost. Not only has the science behind IVF developed and expanded during those years, but social attitudes to assisted reproduction of all kinds have also evolved. ![]() In that relatively short period of time, the individual herself has become a mother of two healthy children and what seemed then to be a miracle of futuristic science has moved on to become part of everyday life, albeit one involving highly specialised skills and techniques which are always evolving. It’s only been 40 years since the birth of Louise Brown, the very first human to be born following conception by In Vitro Fertilisation (IVF). IVI: one of the world’s largest egg banks.
