Oocyte follicle
Oocytes are rich in cytoplasm, which contains yolk granules to nourish the cell early in development. During the primary oocyte stage of oogenesis, the nucleus is called a germinal vesicle. The only normal human type of secondary oocyte has the 23rd (sex) chromosome as 23,X (female-determining), whereas sperm can have 23,X (female-determining) or 23,Y (male-deter… WebFour studies reported on the main result of live birth rate. It is uncertain whether follicular flushing has an impact on live birth rate compared with aspiration alone. This suggests that if a live birth rate of approximately 30% is seen with aspiration alone, the equivalent live birth rate with follicular flushing lies between 20% and 39%.
