Transvaginal Aspiration – SEE VIDEO
With the advanced technique of aspirating small follicles, we are able to retrieve many oocytes per aspiration procedure. The immature oocytes are less fertile that the mature oocytes from preovulatory follicles, but the increase in number outweighs the decrease in fertility. When we only aspirated mature oocytes, we would get one egg 75% of the time. When we aspirate immature follicles, we averaged 6.6 oocytes from the 251 transvaginal aspirations this year. This gives us many more chances for a successful pregnancy.
