When it comes to the various examinations in the IVF cycle, everyone is no stranger to the six hormone tests, AMH tests, yin ultrasound tests and routine examinations for men, which are important indicators to evaluate the feasibility of doing IVF. For many patients, not only these tests should be done, but also a series of tests should be done according to the actual situation of the individual, such as hysteroscopy. So, when is this test done? What are the requirements for the intrauterine environment in an IVF?
When should a hysteroscopy be done?
Hysteroscopy is also a more routine procedure. Usually, when women undergo general anesthesia ** egg retrieval, they will undergo hysteroscopy at the same time, that is, through the fiberoptic light source endoscope, observe the woman's intrauterine environment to understand whether her endometrium is complete, whether there are lesions or abnormalities, etc., so that the IVF doctor can evaluate and diagnose the uterine conditions and prepare for the next step of blastocyst transfer.
As for why you choose to do hysteroscopy at the same time as egg retrieval, the reason why you choose to do hysteroscopy at the same time as egg retrieval is mainly to improve the success rate of IVF. Hysteroscopy can help doctors observe the ovaries and uterine cavity more accurately, provide more accurate navigation and guidance, and at the same time check for abnormalities inside the uterus, such as polyps, fibroids, etc., and carry out corresponding **. This can reduce the stimulation of the ovaries and help improve the success rate of IVF.
Significance of hysteroscopy:
Creating a good gestation environment for blastocysts before transfer is the key to ensuring the success rate of IVF. If some lesions are found during hysteroscopy, hysteroscopic resection can be performed in time to restore the uterine function and morphology well, and ensure the successful implantation and pregnancy of the blastocyst; If the woman's intrauterine disease is serious and beyond the indication range of hysteroscopy, the patient needs to be given time to recover and wait for the intrauterine environment to meet the requirements for pregnancy before transplantation.
Understanding hysteroscopy: Hysteroscopy is an endoscope with a fiber light source, which uses uterine distension medium to expand the uterine cavity, and directly observes the physiological and pathological changes of the cervical canal, uterine cavity and fallopian tube opening through the light guide fiberglass speculum inserted into the uterine cavity, which can not only intuitively and accurately take materials from the lesion tissue for pathological examination, but also directly perform surgery under the microscope**. Hysteroscopy can be described as "one lens with multiple functions", which is suitable for the diagnosis and ** of a variety of intrauterine diseases. At the same time, it can take materials or locate the curettage under direct vision, which updates, develops and makes up for the shortcomings of traditional diagnosis and treatment methods.
What are the requirements for IVF in the intrauterine environment?
The requirements for IVF for the intrauterine environment include good uterine size and shape, appropriate endometrial thickness, no uterine dysplasia, no uterine malformations, no endometritis or endometriosis, no adhesions and other injuries.
At the time of embryo transfer, an endometrial thickness between 8-12mm is optimal, and neither too thin nor too thick is conducive to embryo implantation. At the same time, if there are polyps or fibroids that occupy space, adhesions and other injuries, it may also affect the implantation and development of embryos.
