After some necessary examinations in the early stage of IVF assisted conception, the doctor will formulate a plan, and the formulation of the plan needs to be combined with the specific situation of the patient's body to make it, and then the necessary ** will be carried out. When communicating between different patients, it is easy to find that there is a big difference in the choice of cycle plan, why is the artificial cycle of IVF so different, and what is going on.
IVF artificial cycles.
The artificial cycle mainly includes two different regimens of hormone "replacement cycle" and "direct replacement cycle" after the use of effective gnrha lowering regulation.
Labor cycles are mainly applicable to:
Ovulation disorder is a common "artificial cycle" scheme for patients who do not ovulate normally during the natural cycle, especially for women who do not respond well enough to ovulation induction, and who have long-term persistent anovulation, as well as stubborn polycystic ovary syndrome (PCOS).
There are also patients with endometriosis, and sometimes the doctor may also recommend them to control the lesion through GNRHA downregulation and then use estrogen to "replace the cycle".
The purpose of artificial cycle hormone replacement is to simulate the endocrine state in the natural cycle, which requires the use of large doses (6 8mg days) of exogenous hormones over a longer period of time, which will take longer and cost more than the natural cycle and the microstimulation cycle.
In general, the intimal preparation programs of the three FETs, natural cycle, microstimulation cycle and artificial cycle, each of which is aimed at different patients and has its own advantages, the clinical pregnancy rate of the three ** regimens is relatively the same, about 50% to 60%, and there is no difference compared with fresh cycle transplantation, and the doctor will recommend the use of a more appropriate regimen according to the specific situation of different patients.
Finally, we need to remind patients and friends that the thickness of the female endometrium is not an effective reference index for the receptivity of the female endometrium, and the female endometrium reaching more than 8mm can achieve a better embryo implantation rate, clinical pregnancy, etc., while the miscarriage rate does not increase. We need to work as hard as possible to improve the quality of embryos, so as to effectively increase the planting rate of thawed embryos.
