1. Ultrasonography: This method involves using an ultrasound machine to visualize the embryo and determine its sex based on the presence or absence of certain anatomical features, such as the presence of testicles or ovaries.
2. DNA analysis: This method involves extracting DNA from the embryo and analyzing it to determine the presence of specific sex chromosomes, such as the presence of a Y chromosome indicating a male embryo.
3. Hormone analysis: This method involves analyzing hormone levels in the embryo to determine its sex. For example, higher levels of testosterone may indicate a male embryo.
4. Biopsy: This method involves taking a small sample of cells from the embryo for analysis to determine its sex. This can be done using techniques such as preimplantation genetic testing (PGT).
5. Microscopic examination: This method involves examining the embryo under a microscope to look for specific sex characteristics, such as the presence of sperm cells in a male embryo.
6. Fluid analysis: In some cases, the sex of an embryo can be determined by analyzing the fluid surrounding it, such as in the case of amniotic fluid analysis.
