A comparison of the phases in IVF and ICSI treatment

1.- Ovarian stimulation in the patient is carried out by administering doses of hormones that stimulate ovarian function with the aim of achieving sufficient oocytes. The doses of the aforementioned hormones are personalised to each patient depending on her ovarian reserve and based on the results of antimullerian hormone levels in a blood test and a follicle count for each ovary using a vaginal ultrasound scan. Controlling each patient’s ovarian response is done over a series of vaginal ultrasound scans (an average of 3) and, in some cases, by checking oestradiol (the hormone produced by the ovary) levels in blood. Once the checks indicate that the ovary is ready, oocyte retrieval is scheduled. This period of ovarian stimulation lasts between 8 and 10 days in most women and does not affect the patient’s daily routine. […]

Pre-implantation genetic diagnosis (PGD) consists of studying chromosomal abnormalities and genetic abnormalities in the embryo prior to transfer to the mother. Its purpose is to ensure that children are healthy and put an end to the transmission of a specific condition.
There are two types of PGD: the PGD aimed at selecting embryos that are free of a genetic disorder affecting a single gene (PGD) and the PGD that analyses genetic diseases affecting one or more chromosomes (PGS/PGT-A/CCS or PGS). Their names are sometimes a cause for confusion. The post entitled Are PGD, PGS and CCS all one and the same? clarifies the differences between them. […]
