When the cell mass is fully implanted in the uterus it is called a?
When the cell mass is fully implanted in the uterus, it is called a blastocyst. This is an early stage of development in mammalian embryos, just before the embryo begins to form distinct structures.
When doctors freeze embryos how do they know when to thaw embryos so they can be implanted at the correct stage in the women's reproductive cycle?
Doctors typically time the thawing and implantation of frozen embryos based on the woman's menstrual cycle. This is usually done by tracking her natural hormones and performing ultrasounds to monitor the development of her uterine lining. Once the lining is at the appropriate stage for implantation, the embryos are thawed and transferred.
What could happen to these embryos if they were not used in such treatments?
If the embryos are not used in such treatments, they may be preserved indefinitely in a frozen state, donated for scientific research, or discarded according to the clinic's policies and the wishes of the individuals who created them.
Can an artificially implanted embryo grow inside a male?
No, an artificially implanted embryo cannot grow inside a male as the male body does not have the necessary biological structures, such as a uterus, needed for embryo implantation and growth. Embryos require a female reproductive system to develop and grow into a fetus.
What is the grading of embryos?
Embryos are typically graded based on their developmental stage, cell number, and overall quality. Grading systems can vary depending on the laboratory or clinic, but commonly include categories such as quality (e.g. good, fair, poor), stage of development, and cell symmetry. The grading helps to predict the viability and potential success of an embryo for implantation.
