Retrospective analysis to determine the size of follicles on day of trigger contributing most to the number of mature oocytes retrieved using generalized linear regression and random forest models applied to data from IVF cycles — in which either hCG, GnRHa, or kisspeptin trigger was used. Follicle sizes on the day of trigger most likely to yield a mature oocyte. Using simulated follicle size profiles of patients with 20 follicles on the day of trigger, our model predicts that the number of oocytes retrieved would increase from a mean 9. IVF treatment involves the administration of supra-physiological doses of follicle-stimulating hormone FSH to induce the growth of multiple ovarian follicles. Once ovarian follicles grow to an appropriate size, a trigger is administered to mature the oocytes in preparation for oocyte retrieval.
Follicle Size on Day of Trigger Most Likely to Yield a Mature Oocyte
Richmond, N. Deshpande, H. Lyall, R. Yates, R. No reliable datasets have shown clear criteria for predicting multiple pregnancy. The aim of this study was to eliminate a number of variables by examining only conception cycles to determine ultrasound criteria posing risks of multiple pregnancy. Analyses of ultrasound data on the day of hCG administration allowed study of the role of primary, secondary and tertiary follicle diameters FD.
What is a follicle and how many follicles do you need?
Follicles are not oocytes eggs. Many patients confuse these terms, believing that follicle equals oocyte. These are the cells involved in embryos obtained after fertilization. The follicle is a functional anatomical structure which forms part of the ovary and the egg is the cell that will mature in a microscopic part of inner wall of a follicle over spontaneous or stimulated ovarian cycle in normal conditions. Furthermore, the follicle contains other cell types which produce oestrogen required for normal development of the egg maturation.
F or many couples who pursue fertility treatments, especially for intrauterine insemination IUI or in vitro fertilization IVF , a common ritual becomes visits for morning monitoring during your treatment cycle. The goals of these sometimes frequent appointments are to make necessary mid-course adjustments to your treatment protocol and to determine the best timing for ovulation or egg retrieval by monitoring estrogen levels and follicle size. This helps us achieve the best possible outcome for you while avoiding potential complications.
