IVF - Huntington Reproductive California Fertility Clinics
|
|
IVF or, in vitro
fertilization, was first successfully performed
in 1978 and resulted in the birth of the first baby born
on July 25, 1978. When Louise Brown's mother gave birth
to her daughter at Oldham Hospital near Manchester,
England, the world reacted as if she, and IVF, were a creation
of science fiction.
IVF was a major breakthrough in treating infertility and is responsible for the birth
of more than 500,000 healthy children around the world. IVF and donor egg success
rates have improved consistently over the last several
years. New procedures, such as ICSI, have evolved to treat conditions such as male infertility and have enabled thousands of otherwise infertile men to father children.
Huntington has six
IVF clinics located in southern California staffed by Fellowship trained and board certified infertility doctors. IVF requires a team of experts, takes several
weeks, and consists of five basic steps.
IVF
- Ovarian Follicle Development
IVF requires numerous follicles (eggs), however, women usually grow
a single egg each month. The patient undergoes ovulation induction with FSH which can
be used alone, or in combination with other medications,
to induce several follicles to develop. The monitoring of egg development
is accomplished in three ways:
- Cycle ultrasound
monitoring of follicles their during growth
- Cycle monitoring
of blood or urinary estrogen (E2), progesterone
(P4), and luteinizing hormone (LH)
- Cycle data is interpreted
by the infertility specialist
The team evaluates
cycle data on an ongoing basis for the appropriate timing
of the administration of the human chorionic gonadotropin
(hCG) injection that triggers the final stages of ovulation.
The hCG injection is usually given about 35 hours before
egg retrieval is scheduled.
Egg Harvesting, Oocyte Retrieval
IVF originally required
that the eggs be retrieved by laparoscopy. Today, they
are collected by transvaginal ultrasound-guided oocyte
aspiration. This is a simple technique that involves
the introduction of a small needle through the vaginal
wall guided by an ultrasonic probe. Egg harvesting
is conducted at our clinic under local
anesthesia and IV sedation.
IVF Laboratory
The eggs must be combined with sperm for fertilization to occur. After the oocyte collection
procedure, a "baby incubator" which houses
a powerful dissecting microscope receives the follicular
fluid containing the eggs. This fluid is placed in a
special culture medium which consists of several essential
chemicals. At this point in the cycle, the eggs remain in the carefully-controlled
extracorporeal system for 4-6 hours before the embryologist
adds the specially-processed sperm to allow the fertilization
process to occur.
IVF - Uterine
Embryo Transfer
IVF embryo
transfer is not a complicated procedure and is performed
in our office without anesthesia. The embryos are placed
in a tiny catheter and then introduced by the infertility specialist into the uterus through the cervix into the endometrial
cavity.
We require the patient remain lying down for about an
hour.
Patients
are told to absolutely restrict their physical activities
for the first 24-72 hours and moderately restrict them until a pregnancy test is performed approximately
9-12 days post transfer.
Luteal
Phase Monitoring & Support
The luteal
phase of the cycle consists of monitoring of blood levels
of progesterone, estradiol, and BhCG (pregnancy tests).
If there is a positive pregnancy test, close monitoring
of the early pregnancy is highly advisable. We continue
to perform the blood tests plus the first pregnancy
ultrasound for detection of the baby's heartbeat and
evaluation of the number of embryos implanted is usually
done between the 4th and 6th week post transfer.
ICSI, TESA, MESA
ICSI is employed
in cases of male factor infertility. ICSI entails inserting
a single sperm directly into each egg. TESA and MESA are
used to extract sperm directly from the males reproductive
tract. Your infertility doctor will discuss ICSI with you prior to starting the IVF cycle.
Embryo Cryopreservation
Embryo
cryopreservation
is possible when
there are extra embryos remaining after incubation.
Embryo cryopreservation means that embryos can be thawed
and used in future cycles thus reducing medication
costs.
Donor Egg IVF
IVF with Donor eggs is used when a woman cannot use
her own eggs. This may be due to age, disease, cancer treatments such as radiation
or chemotherapy, and other factors. In vitro fertilization
success rates using donor eggs are typically high. See
the donor egg pages.
Success Rates
IVF success rates vary
according to variables including the cause(s) of a couple's infertility, whether or not male factor is present, in
which case ICSI is recommended, female age and others.
IVF success rates are discussed on a separate Web page. We
also feature an excellent article covering factors that
can improve success rates by Dr. Wilcox.
