IVF terminology parsing
【Weekly】
It means that after the husband and wife have made sure to start IVF after the preliminary physical examination and various preparations, the doctor will formulate the most appropriate IVF cycle according to the results of the previous examination, which also means that the first step of the IVF journey has officially entered.
【Downgrade】
A process that temporarily reduces the natural production of reproductive hormones by intervening in the pituitary function of the reproductive endocrine system through artificial drugs is called hyporegulation. Downregulation allows for better control of the stimulation cycle and helps prevent early ovulation. The purpose is to promote the synchronous development of a batch of follicles, and strive to obtain more mature follicles at the same time, thereby improving the success rate of test tubes.
【Induction】
Ovulation induction is short for controlled hyperovulation induction in IVF. In order to ensure the success rate of IVF, it is necessary to use drugs to promote ovulation, with the purpose of making multiple eggs mature at the same time, ensuring the quality of eggs, and thus obtaining multiple embryos.
【Night Needle】
During IVF treatment, when the follicle grows to a certain stage, a special drug is needed to promote the eventual maturation of oocytes. Because the injection time of this needle is generally arranged in the evening, it is called "night needle".
【AMH】
AMH, known as "anti-Müller's tube hormone", is secreted by primary follicles and small sinus follicles in the ovaries, which can assess egg reserve in the ovaries, is one of the important hormones for follicular development, and is also known as a "monitor" of ovarian age.
【FSH】
FSH, full name "follicle-stimulating hormone or follicle-stimulating hormone", is an indispensable hormone for follicle development, and its physiological role is to directly promote the growth of follicles and sinus-like follicles in the sinuses of the ovaries.
【Fresh embryo】
Fresh embryo transfer refers to the fact that 3 days after the woman's egg retrieval, the egg and sperm are fertilized in vitro to form an early embryo, and the embryo is transferred directly in a fresh cycle, corresponding to the transfer of frozen embryos.
【Blastocysts】
The embryo formed on the 3rd day after fertilization is called the fissure embryo, and the stage of development to the 5th to 6th day is called the blastocyst. Embryos at this stage can be assessed for developmental potential, synchronized with the development of the endometrium, and more in line with the physiological state
