In Vitro Fertilization
In vitro fertilization (IVF) involves ovarian stimulation, collection of eggs and sperm and fertilization of the eggs with the sperm in the laboratory. Fertilized eggs are cultured to form embryos before they are transferred into the uterus.
Intra-cytoplasmic Sperm Injection(ICSI)
Intra-cytoplasmic sperm injection (ICSI) involves the injection of a single sperm with good vitality and normal morphology into the inner part of an egg. The day after sperm injection, fertilization and mitosis of oocytes were assessed and in vitro development was monitored. Then the fertilized egg will be transfer to the uterine cavity to continue to grow and develop into a fetus. ICSI works on infertility caused by male factors.
percutaneous epididymal sperm aspiration, PESA
testicular sperm aspiration, TESA
fine needle aspiration mapping, FNA-mapping
Fine needle aspiration mapping (FNA mapping) is to obtain sperm from testis / epididymis through testicular biopsy and fine needle aspiration. Then the sperm from puncture can be used for intracytoplasmic sperm injection. It is a good option for patients with obstructive azoospermia and ejaculatory disorder.
Intrauterine Insemination (IUI) is a fertility treatment that involves placing sperm inside a woman’s uterus to facilitate fertilization. According to the source of sperm, it can be divided into artificial insemination by husband and artificial insemination by donor.
The IUI procedure takes only a few minutes and involves minimal discomfort. It is a less invasive and less expensive option compared to in Vitro Fertilization. IUI may be selected as a fertility treatment for any of the following conditions: Cervical infertility, immune infertility, poor semen quality of husband, poor semen liquefaction, oligospermia and asthenospermia
We can use vitrification to successfully freeze eggs immediately after the collection procedure, store the egg/sperm in liquid nitrogen, and then thaws the egg/ sperm when it needs to be used.
Assisted hatching is a technique by which a tiny aperture or slit is made in the zona pellucida (translucent outer layer) of the embryo by physical or chemical means to facilitate the release of the developing embryo and its subsequent implantation after transfer into the uterus.
Embryo vitrification allows us to freeze any good quality embryos that remain after embryo transfer or if transfer needs to be delayed. For IVF-ET failure patients, they can thaw these embryos in their next cycle and conduct frozen-thawed embryo transfer (FET).
