Does brown blood indicate that the embryo has been biochemical? Is the situation true? During IVF, many couples pay attention to their physical condition, especially when abnormal situations occur, which can lead to concerns and confusion. Among them, brown blood is a common question point, and many people believe that brown blood may be a manifestation of embryonic biochemistry. This article aims to scientifically interpret the meaning of brown blood and elaborate on related issues.

1、 Definition and causes of brown blood:

Brown blood refers to a mixture of bright red blood and old blood, exhibiting a characteristic of dark red to brown. The appearance of brown blood does not necessarily indicate that the embryo has undergone biochemistry, it may be the result of other physiological or pathological factors. The following are some possible reasons for the appearance of brown blood:

1. Endometrial exfoliation: Before and after menstruation, the endometrium will detach and discharge, which may be accompanied by the appearance of brown blood.

2. Suffering from gynecological diseases such as uterine fibroids and endometriosis, which may cause bleeding in the uterus and cause brown blood.

3. Excessive and intense sexual activity: Excessive and intense sexual activity may cause minor tears in the vagina or cervix, resulting in the discharge of brown blood.

4. Hormone therapy: The use of some hormone drugs, such as progesterone, may cause the appearance of brown blood.

2、 The relationship between brown blood and embryonic biochemistry:

Embryo biochemistry refers to the occurrence of abnormalities during the early embryonic development process after implantation of a fertilized egg, ultimately leading to the cessation of embryonic development and miscarriage. Brown blood is not a direct indicator of embryonic biochemistry, as it may be caused by other factors. During IVF, the appearance of brown blood may also be a normal reaction, such as implantation bleeding. During the implantation of a fertilized egg, a small amount of blood may seep out, which may cause the appearance of brown blood, but it does not necessarily indicate that the embryo has undergone biochemical changes.

3、 Diagnostic methods for embryonic biochemistry:

To confirm whether the embryo has undergone biochemistry, a series of tests and observations, such as HCG blood testing, ultrasound examination, etc., are required. HCG is a human chorionic gonadotropin that gradually increases after implantation of fertilized eggs. If the HCG level continues to increase, it indicates normal embryonic development; If HCG levels decrease or stagnate, it may indicate embryonic biochemistry. Ultrasound examination can observe the size and morphology of embryos, further confirming their development.
