ICSI (Intracytoplasmic Sperm
Injection)
ICSI has been one of the greatest
advances in the treatment of male factor infertility. ICSI
involves injecting a single sperm into a mature egg. This
procedure involves an embryologist manipulating under a
microscope a mature retrieved egg while injecting a micro
needle loaded with a single sperm directly into the mature
egg. This advancement in the hands of an experienced
embryologist can increase the probability of fertilization to
as much as eighty five percent. Indications for the ICSI
procedure include couples with:
- Severely abnormal semen analysis, including low sperm
counts below 20,000,000, poor motility, and abnormal
morphology.
- Men requiring microsurgical epididymal sperm aspiration
(MESA) or testicular sperm aspiration (TESA).
- Failed fertilization of embryos on prior IVF
attempts.
Co-Culture of
Embryos
The embryos of some couples have cytoplasmic fragmentation resulting in
poor quality embryos. By culturing these embryos with
cells similar to those that line the woman’s fallopian tubes and
uterus the fragments can be reduced and the quality of the embryo
improved.
Preimplantation Genetic Diagnosis
(PGD)
Involves taking a single cell from a developing embryo and analyzing
its genetic makeup. This is done to find chromosomal and genetic
disorders early. PGD can be used for couples that are at risk for
transmitting a genetic disease to their children such as Cystic
Fibrosis, Sickle Cell, Tay Sachs, etc. It can also screen for
chromosomal abnormalities that can cause miscarriage or prevent
pregnancy from occurring while also checking for certain genetic
diseases, such as Down's syndrome-much like the amniocentesis test, PGD
does confirm the sex of the embryo as part of the complete chromosome
report but is not generally used for this purpose.
MicroSort® - Gender Selection
For decreased prevention of X-Linked Genetic Diseases. The male’s sperm determines the sex of the
baby, male or female. MicroSort is a patented process that separates the male
and female sperm prior to fertilization. After separation, the sperm is used in
conjunction with an IVF/ICSI procedure at our facility. For more information on MicroSort click on Education and/or go to microsort.net.
Assisted
Hatching
This technique is used to improve the embryo’s implantation. Assisted
Hatching involves opening a small hole in the outer membrane known
as the zona pellucida of the embryo. This opening allows the embryo to
leave its “shell” and implant into the uterine
lining.
Embryo and Gamete
Cryopreservation
Cryopreservation (freezing) of embryos
(fertilized eggs) is utilized when the number of embryos produced
during an IVF cycle exceeds the number of embryos placed in the
uterus on day three or five embryo transfer. Once
frozen, these embryos may be thawed and transferred in another cycle
at a later time. Gamete cryopreservation (freezing)
is used to freeze sperm so that it can be used at a later
time. Visit our cryopreservation website to learn more about egg and sperm freezing.
Semen
Analysis

A semen analysis measures the quantity and quality of the sperm. Several
characteristics are examined, including the ability of sperm to move
(motility), forward progression (the quality of movement), sperm
count (the number of sperm), volume of semen (the total amount of
ejaculate), as well as the size and shape of the sperm
(morphology).
The semen analysis must be collected within 1 hour prior to reaching the
laboratory or be collected onsite. The laboratory should provide a
sterile container and instructions on masturbation collection. The
specimen must be processed immediately. Many
laboratories do not have the ability to perform the semen analysis
onsite and may ship the specimen to another city or state, thus not
processing the specimen until several hours later or even the next
day. This delay would severely impact the accuracy of the
results. Complete Andrology services including Semen Analysis are
performed daily onsite at Houston Fertility Center.
Sperm Wash
This is a process to remove the sperm from the
ejaculate. This provides a highly concentrated amount of sperm that
can then be introduced into the cervix or the uterus.
