The day after egg collection (about 16-18 hours after collection), embryologists will assess how many of the eggs are fertilised before storing them, in an appropriate environment for daily assessment of embryo development under a microscope. Transfer usually takes place 3 to 5 days after egg collection. However, on some occasions embryos will be frozen because the transfer might have to be postponed due to multiple egg development (OHSS) and high Oestradiol levels. The patient’s bladder must be full for the procedure as this assists to straighten the cervix for ease of transfer and highlights the endometrium better. Once the patient is on the examination table, under sterile conditions a speculum will be inserted into the vagina to reveal the cervix. Embryos are then transferred into the uterus using a very fine specialised catheter. The transfer procedure is painless and does not require anaesthesia (slight sedation-anaesthesia might be necessary for patients who will not even allow vaginal examination- like patients suffering from vaginismus). After the transfer it is better to rest for between 30- 60 minutes, during this time the patient will be provided with detailed information about points of consideration and medication. A pregnancy test (Beta Hcg) or early morning pregnancy test may be performed 12 days after the transfer to determine if conception has been achieved.

IUI method is an assisted reproductive method performed on patients who have not been able to fall pregnant despite regular unprotected sexual activity for a year and has received the diagnosis that they are infertile. Insemination method is quite simple and is almost painless application compared to other methods. Once the necessary controls and checks are in place i.e. the fallopian tubes are checked and are clear and open (with the aid of an HSG), sperm is active with a high count and motility and the ovaries seem to be developing follicles and there is no problem with ovulation. The next process would be to track follicular development after 7 days of a bleed and when ovulation occurs to inject the prepared sperm (prepared in the laboratory) via the uterus. If the sperm fertilises the egg itself then IVF is not necessary.

IVF is the procedure of creating an embryo in laboratory conditions and transferring the embryo to the uterus. In the conventional IVF method the egg collected from the female is brought together with an adequate quantity of sperm from the male in special laboratory conditions allowing the fastest and most fertile sperm to enter the egg naturally. About 16-18 hours will be allowed for fertilisation and then the situation will be evaluated under microscope. However this treatment method requires an adequate quantity of sperm and eggs. The method may fail if sperm quality or quantity is poor or if egg quantity is inadequate

The IMSI method allows a much more accurate sperm selection by examining the sperm under considerably greater magnification (x6000-x8000). By doing this IMSI increased chances of success for couples suffering especially from sperm defects. Remaining IVF stages and microinjection procedures are exactly the same.
