Gamete
intrafallopian transfer (GIFT)
Here the egg and the sperm are placed in the fallopian tube. Eggs
are retrieved under ultrasound guidance and evaluated. A semen sample
is collected two hours prior. The best eggs and the sperms are mixed
and transferred into the distal end of the fallopian tube by ultrasound-guided
transcervical tubal transfer. Other alternative methods are hysteroscopic
tubal cannulation with transfer, and falloposcopic transfer of gametes.
The process of fertilization and transport down the tube into the
uterus is allowed to proceed naturally.
As
a logical alternative, the zygote (fertilized egg before division)
is placed in the fallopian tube after uniting the sperm and the
egg in vitro. This technique is called Zygote intrafallopian tube
transfer (ZIFT).
Semen Intrafallopian transfer (SIFT)
BACC pioneered this ART technique in India. The center adopts a
simplified cost-effective technique called the translaparoscopic
semen intrafallopian transfer. Here prepared semen is directly introduced
via the laparoscope into one or both the fallopian tubes, in time
with ovulation. It eliminates the use of expensive equipment required
for IVF or GIFT.
Blastocyst
transfer
The
blastocyst is a fertilized egg, which has undergone divisions. In
this technique the fertilization of the ovum or the egg and the
sperm is undertaken under optimal conditions in the laboratory.
When the blastocyst stage is reached it is transferred into the
uterus. This procedure is indicated in older women and those with
previous ART failures
Donor
programs
The
donor identity is kept in strict confidence at the ART center and
never revealed to the couple. Only a description and the medical
history of the donor may be provided.
Embryology
This
division was set up with a view to improve success rates in assisted
reproduction techniques, by selecting the best embryos for implantation
inside the uterus. Embryo freezing, a means of preserving embryos
with no loss to their structural or functional integrity is also
undertaken at BACC. The purpose of this is to utilize the embryos
at a later date, in cases of failed fertilization by ART, thereby
reducing cost to the patient.
Fetal
therapy
Procedures
are performed on the fetus with the intent to give it the optimal
in utero milieu to develop and grow. The indications are Rhesus
incompatibility, multifetal pregnancy and oligohydramnios.
Rhesus
incompatibility - The fetus is severely handicapped due to a
mismatch in the blood groups of the mother and the fetus. A suitable
blood type is injected under ultrasound guidance into the fetal
peritoneal cavity or into the umbilical circulation of the fetus.
Multifetal
pregnancy where there is a space constraint in the uterus for
normal growth of the fetuses. Selective
reduction is undertaken to leave behind only two fetuses. This
is performed in the first trimester of pregnancy. Selective reduction
is also an option for selectively terminating a fetus with a genetic
defect.
Oligohydramnios
- The amount of fluid in the amniotic cavity is decreased to the
extent that the intrauterine environment becomes unfavorable to
the fetus. Normal saline is instilled into the uterine cavity transabdominally.
