Causes of bleeding after IVF transplantation
IVF is an assisted reproductive technology, which helps infertile couples realize their desire for pregnancy and childbirth through in vitro fertilization and embryo transfer. However, bleeding sometimes occurs after IVF transplantation, which brings unnecessary concerns to patients. The causes of bleeding after IVF transplantation will be described in detail from several aspects.
1. Endometrial damage
Test tube baby transplantation needs to enter the uterine cavity through the cervix, and this process will inevitably cause some damage to the endometrium. When transferring embryos, inserting a catheter into the uterine cavity may scratch and compress the endometrium, causing local bleeding. In addition, after embryo implantation, blood vessels in the uterus may also be eroded by the embryo, causing bleeding.
Usually, the bleeding caused by such endometrial damage is not serious, but only causes slight bleeding traces. Bleeding will generally stop itself within hours or days, and will not have a significant impact on embryo implantation.
2. Uterine fibroids or polyps
Uterine fibroids and polyps are also one of the common causes of bleeding after IVF transplantation. Uterine myoma is a common uterine tumor, which is composed of uterine smooth muscle cells; Polyps are masses formed on the endometrium. These masses can lead to endometrial bulge or bulge, damage the integrity of the endometrium, and cause bleeding after transplantation.
If women with uterine fibroids or polyps are found, they should be treated or surgically removed in time before IVF transplantation to reduce the risk of postoperative bleeding.
3. Side effects of ovulation promoting drugs
In the process of IVF transplantation, in order to increase the number of patients' eggs, ovulation promoting drugs are often used to promote ovulation in vitro. These drugs can stimulate ovarian ovulation, increase the number of eggs, and improve the probability of pregnancy.
However, ovulation promoting drugs may also bring some side effects, such as ovarian hyperstimulation syndrome (OHSS). OHSS may lead to follicle rupture, exudation of follicular fluid, vascular leakage, etc., which may lead to post transplantation bleeding.
4. Existence of gynecological diseases
Some gynecological diseases, such as cervical erosion, cervical intraepithelial neoplasia, etc., often make the cervix more fragile due to the existence of lesions, which is easy to cause bleeding after transplantation.
If women with gynecological diseases want to have IVF transplantation, comprehensive examination and treatment should be carried out before the operation. This can reduce the risk of postoperative bleeding and improve the success rate of embryo transfer.
Summary
The causes of bleeding after IVF transplantation include endometrial damage, uterine fibroids or polyps, side effects of ovulation promoting drugs, and the presence of gynecological diseases. Although these causes may lead to bleeding, in most cases the bleeding is not serious and will stop itself within hours or days. Before IVF transplantation, patients should be comprehensively examined and evaluated to reduce the risk of bleeding and improve the success rate of embryo transfer.
