![]() So not only we are going to see the progesterone levels, but also the estrogen levels. ![]() We shouldn’t proceed with fresh embryo transfer if, for example, we’ve been having loads of follicles growing during the simulations, more than 15 follicles of 16 millimetres on the day of the trigger, it’s better to freeze the embryo and do a transfer later on so that we don’t get that risk of hyperstimulation syndrome.Īlso, hormones are going to help us to know if there is an added risk. no risk of having a Hyperstimulation syndrome (OHSS).blood progesterone levels, less than 1 ng /ml the day of the trigger (if they are higher, it means that the window of implantation could be affected, and therefore, it’s not good to go ahead with fresh embryo transfer).3 layer endometrium, more than 7 millimetres of thickness.What are the requirements for a fresh embryo transfer to take place? It can be during a substituted cycle with hormonal treatment, or sometimes we can also do a natural modified cycle. We can prepare the endometrium for a fresh embryo transfer during an IVF and for a frozen embryo transfer, in which there are 2 basic options of preparation. There are different ways in which we can prepare the endometrium for an embryo transfer. This is a very important part of a woman’s organism during her fertility treatment. Afterwards, we also need progesterone, which is produced after ovulation, and this hormone helps supply the lining and stimulates the glands to grow and nourish the early embryo. First, the oestrogens are the highest levels of hormones, and they help the lining to thicken for a potential pregnancy. Due to the ovarian hormones produced during a natural cycle, the endometrium is changing. So there are different moments where we get different types of the endometrium, but everything is thought so that we can get pregnant. This tissue is special in women’s organisms because it changes depending on the timing of the ovarian cycle. ![]() The endometrium is a tissue that we have inside the uterus, it is the innermost layer where the embryo implantation and the fetus development take place. She finished by explaining the meaning of endometrial tests that can be done to see when it’s indicated or not. After that, she focused on different types of preparation for fresh embryo transfers and frozen embryo transfers. She started with the definition of the endometrium. In this webinar session, Dr Elena Santiago, Fertility Specialist at Clinica Tambre, Madrid, explained what tests can be performed and what can be improved to increase the chances of successful embryo transfer.ĭr Elena Santiago started her presentation by explaining what she’d like to discuss during this webinar.
