Causes of massive hemorrhage in test tube infants
In vitro fertilization (IVF) is the process of cultivating embryos in the laboratory through in vitro fertilization (IVF) technology, and then transferring the embryos back to the mother's uterus. Although this technology has become an effective means to solve the problem of infertility, compared with conventional pregnancy, IVF is at risk of massive bleeding. Massive bleeding may have serious effects on the embryo and mother. The following are the main causes of IVF massive hemorrhage.

1. Endometrial abnormalities
Endometrial abnormalities may be a major cause of massive hemorrhage in IVF. The endometrium is the place where the embryo is implanted. If the endometrium is abnormal, the embryo cannot be implanted correctly, which is easy to lead to bleeding. Endometrial abnormalities can be caused by pathological conditions such as endometriosis, polyps or fibroids. In addition, excessive or insufficient endometrial hyperplasia may also lead to massive bleeding in IVF.
Medical research shows that after IVF transplantation, women with endometriosis are prone to massive bleeding due to the stimulation of ectopic endometrium. Therefore, before IVF transplantation, doctors usually conduct endometrial pathological examination to exclude such pathological conditions.
2. Abnormal blood coagulation
Abnormal blood coagulation is also one of the common causes of massive hemorrhage in test tube infants. In the process of IVF, doctors usually give hormone treatment before embryo transfer to help the embryo implant smoothly. However, these hormones may also affect the coagulation function of blood, resulting in too thin blood, increasing the risk of IVF bleeding.
In addition, some hereditary diseases, such as coagulation factor defect or abnormal platelet function, may also lead to massive hemorrhage in IVF. Therefore, before the IVF process, the doctor will check the patient's blood coagulation function to rule out abnormal blood coagulation.
3. Abnormal uterine artery
Abnormal uterine artery is also a common cause of massive hemorrhage in IVF infants. Long before IVF surgery, doctors usually use ultrasound to assess the condition of the patient's uterine artery. If the uterine artery is abnormal, such as artery rupture or aneurysm, it may cause massive bleeding during IVF transplantation.
The abnormality of uterine artery may be congenital, or it may be caused by other diseases or surgery. Therefore, doctors will pay close attention to the situation of uterine artery during IVF, and take timely measures to avoid massive bleeding.
4. Improper embryo implantation technology
Improper embryo implantation technology in IVF surgery is also a potential cause of massive hemorrhage. The process of embryo transfer requires the doctor's precise operation to ensure the successful implantation of the embryo and avoid bleeding. If the position of embryo implantation is not accurate, it is easy to cause bleeding.
In addition, in the process of embryo implantation, if the surgical tools used are not suitable, or there is accidental injury during the operation, it may also lead to massive hemorrhage of IVF. Therefore, doctors need to be very careful in the operation and follow the relevant operating specifications to ensure the safety of embryo implantation.
summary
There are various reasons for massive hemorrhage during IVF. Abnormal endometrium, abnormal blood coagulation, abnormal uterine artery and improper embryo implantation technology may lead to massive hemorrhage in IVF. In order to reduce the risk of massive bleeding, doctors usually carry out relevant examinations and assessments before the IVF process, and select appropriate treatment methods according to the special conditions of patients. Although IVF faces a high risk of massive bleeding, with the continuous progress of medical technology, most IVF babies can be born successfully, bringing new hope to infertile patients.
