Intrauterine insemination (IUI) involves a laboratory procedure to separate fast moving sperm from more sluggish or non-moving sperm. The fast moving sperm are then placed into the woman’s womb close to the time of ovulation when the egg is released from the ovary in the middle of the monthly cycle. After the IUI is completed, the patient can resume any activities.
In IVF, this process of fertilisation happens outside the woman’s body. IVF has changed the prospects in the female. A woman’s eggs are surgically removed and fertilised in a laboratory using sperm that has been given as a sperm sample. The fertilised egg, called an embryo, is surgically implanted into the woman's womb. One cycle of IVF takes between four and seven weeks.
Intra-cytoplasmic sperm injection (ICSI) differs from conventional in vitro fertilisation (IVF) in that the embryologist selects a single sperm to be injected directly into an egg, instead of fertilisation taking place in a dish where many sperm are placed near an egg. In cases of repeated failure with conventional In Vitro fertilization, ICSI could be considered to maximize the chances.
Embryo transfer takes place after eggs have been collected and fertilised in the laboratory.
Depending on the situation between one and three of the best quality embryos are selected and then transferred to the woman’s womb.
An embryo must successfully attach itself to the wall of the womb for pregnancy to begin.
Egg / Embryo donation are types of fertility treatment used to help couples to conceive.
Egg donation is when eggs from a donor are fertilised with your partner’s sperm in a laboratory dish. The resulting embryos are then transferred to your uterus (womb).
Embryo donation is an option if you and your partner require both egg and spermdonation, or if you are a single woman who cannot use your own eggs.
Surrogacy is an arrangement between a woman and a couple or individual to carry and deliver a baby. Women or couples who choose surrogacy often do so because they are unable to conceive due to a missing or abnormal uterus, have experienced multiple pregnancy losses.
The advantage of gestational surrogacy to the parents is that the embryo is created from the woman’s egg and the man’s sperm, so it is biologically theirs.
A blastocyst is an embryo which has been left to develop until day 5 or 6 and presents a complex cellular structure formed by approximately 200 cells. A blastocyst must successfully attach itself to the wall of the womb for a woman to become pregnant. The blastocyst phase is the development stage prior to implantation of the embryo in the mother’s uterus.
A sperm bank, semen bank or cryobank is a facility or enterprise that collects and stores human sperm from sperm donors for use by women who need donor-provided sperm to achieve pregnancy. Sperm donated by the sperm donor is known as donor sperm, and the process for introducing the sperm into the woman is called artifif icial insemination, which is a form of third party reproduction.
Andrology is the medical specialty that deals with male health, particularly relating to the problems of the male reproductive system and urological problems that are unique to men. It is also known as "The science of Men".
It is the counterpart to gynaecology, which deals with medical issues which are specf ic to the female reproductive system.
Testicular Sperm Aspiration (TESA) ocuurs when a fine needla is inserted into the testis and samples of tissue containing sperm are obtained by gentle suction. If insufficient sperms are obtained using this technique, then your Consultant amy decide that Testicular Sperm (TESE) is the best course of action. TESE involves taking a biopsy (tissue sample) through a small incision in the scrotum.
MESA involves aspiration of sperm from the epididymis with a fine needle. It is a surgical procedure and is carried out under a general anesthetic.
Sperm collected using this procedure are often of poor quality but are usually suitable for cryostorage. One aspiration may provide enough sperm for several attempts at IVF using ICSI. MESA can be performed well in advance of any proposed IVF procedure.
PESA is a simple technique to obtain sperm for Intra Cytoplasmic Sperm Injection (ICSI) in men who have an obstruction of the vas deferens, either due to vasectomy or other obstruction. To minimize scarring and damage, PESA usually is attempted on one side only. It is sometimes necessary to aspirate from both sides. Suffif f icient sperm for ICSI is obtained in 80% of attempts. In 10% of cases enough suitable sperm is found for cryopreservation.
