ASSISTED CONCEPTION TECHNIQUES

The birth of Louise Brown on July 25th 1978 was a landmark in the treatment of infertility.
Initially, women with tubal damage were considered for IVF-ET during spontaneous cycles. The technique is now offered for a number of other indications and generally carried out in cycles with ovarian stimulation.
In vitro fertilization and embryo transfer (IVF-ET) involves the fertilization of gametes in the laboratory and transfer of embryos to the uterus. There are a number of related techniques that are carried out to overcome barriers to enhance fertilization. The com¬monly used techniques are listed below.
IVF in vitro fertilization
DI donor insemination
GIFT gamete intrafallopian transfer
ZIFT zygote intrafallopian transfer
SUZI subzonal insemination
ICSI intracytoplasmic sperm injection
TESA testicular sperm aspiration
PESA percutaneous sperm aspiration
MESA micro-epididymal sperm aspiration

Of all the techniques described above, IVF and ICSI are the most commonly used techniques
Indications of IVF include:
• Tubal damage
• Unexplained infertility
• Endometriosis
• PCOS
• sperm disorder:
• non-obstructive azoospermia
• obstructive azoospermia
