Heavy bleeding and lots of blood clots after transplantation

Transplantation. The transplantation mentioned here does not refer to the transplantation of flowers, plants or trees, but the transplantation of embryos. This is a highly technical job that can only be carried out when the medical level reaches a certain level. Embryo transplantation can also be described as fertilized egg transplantation. The simple explanation is that the male embryo is transplanted into the female's body for further development. Embryo transplantation is a major operation, so why does heavy bleeding and blood clots occur after the operation?

First of all, you should go to the hospital for treatment as soon as possible.

Embryo transplantation, also known as fertilized egg transplantation, refers to the technology of transplanting early embryos of female animals, or embryos obtained through in vitro fertilization and other methods, into the body of a female animal so that it continues to develop into a new individual.

nature

The process by which a donor who produces embryos and a recipient who bears the embryos work together to reproduce offspring.

significance

The reproductive capacity of excellent female individuals can be fully utilized.

Greatly shortens the reproductive cycle of the donor itself

Increases the number of offspring that the donor can reproduce throughout his or her lifetime

Physiological basis

(1) The physiological changes in the reproductive organs of donor and recipient animals of the same species are the same, providing the same physiological environment for the donor embryo to be transplanted into the recipient.

(2) Early embryos are in a free state for a certain period of time, which makes it possible to collect embryos.

(3) The recipient has basically no immune rejection reaction to the foreign embryo transplanted into the uterus, which provides the possibility for the embryo to survive in the recipient.

(4) The donor embryo can establish normal physiological and tissue connections with the recipient uterus, but the genetic characteristics of the donor embryo will not be affected in any way during the gestation process.

The offspring produced by embryo transplantation receive nutrition from the recipient and develop into a new individual, but their genetic material comes from their true parents, the donor animal and the male animal that mates with it. Embryo

When the fetus is transferred into the uterus, the highest pregnancy success rate is during the blastocyst stage.

By using embryo transplantation, we can develop the reproductive potential of female livestock with excellent genetic characteristics and expand the breeding herd more quickly. Under natural conditions, female livestock such as cattle and horses usually give birth to one baby a year and only produce about 16 offspring in their lifetime; there are no more than a hundred pigs. The use of embryo transplantation saves high-quality female animals from the lengthy gestation period. Soon after the embryo is removed, they can go into estrus, mate and be fertilized again, thus producing more offspring within a certain period of time. If gonadotropin is injected into female animals, they can be induced to release more eggs than naturally during one estrus period, and multiple embryos can be obtained for transplantation. In addition, since embryos can be stored for a long time and transported over long distances, they also provide better conditions for the establishment of livestock gene banks, the introduction and exchange of breed resources, and the reduction of disease transmission.
