'invitro fertilization'

This was a breakthrough in infertility treatment. The eggs are retreived by vaginal route (Ultra sound guided ovum pickup) and invitro insemination is done with washed sperm in the laboratory. Fertilization is achieved within 24 hours, Day 3 embryo transfer is done and the 4 to 8 cell embryos are carefully placed back in to the uterus

• This technique has revolutionized treatment of male factor sterility. • A single sperm is injected in to the oocyte using a robotic micromanipulator to achieve fertilization. • Even in patients with nil sperms we can retrieve few sperms from the testis using methods such as PESA (Percutaneous epididymal sperm aspiration, MESA (Micro epididymal sperm aspiration) and TESE (Testicular sperm extraction) • Impossible cases have become pregnant using the above techniques.

A recent advance in infertility treatment involves growing human embryos in the laboratory to a later "blastocyst" stage before transferring them into the uterus following in vitro fertilization.
