However, in mid-2006 the fda cleared a device that allows embryologists to select mature sperm for icsi based on sperm binding to hyaluronan, the main constituent of the gel layer ( cumulus oophorus ) surrounding the oocyte. The device provides microscopic droplets of hyaluronan hydrogel attached to the culture dish. The embryologist places the prepared sperm on the microdot, selects and captures sperm that bind to the dot. Basic research on the maturation of sperm shows that hyaluronan-binding sperm are more mature and show fewer dna strand breaks and significantly lower levels of aneuploidy than the sperm population from which they were selected. A brand name for one such sperm selection device is picsi. 16 A recent clinical trial showed a sharp reduction in miscarriage with embryos derived from picsi sperm selection. 17 'washed' or 'unwashed' sperm may be used in the process.

A medical animation still showing icsi procedure. The procedure is done under a microscope using multiple micromanipulation devices ( micromanipulator, microinjectors and micropipettes ). A holding pipette stabilizes the mature oocyte with gentle suction applied by a microinjector. From the opposite side a thin, hollow glass micropipette is used to verkoop collect a single sperm, having immobilised it by cutting its laser tail with the point of the micropipette. The oocyte is pierced through the oolemma and the sperm is directed into the inner part of the oocyte (cytoplasm). The sperm is then released into the oocyte. The pictured oocyte has an extruded polar body at about 12 o'clock indicating its maturity. The polar body is positioned at the 12 or 6 o'clock position, to ensure that the inserted micropipette does not disrupt the spindle inside the egg. After the procedure, the oocyte will be placed into cell culture and checked on the following day for signs of fertilization. In contrast, in natural fertilization sperm compete and when the first sperm penetrates the oolemma, the oolemma hardens to block the entry of any other sperm. Concern has been raised that in icsi this sperm selection process is bypassed and the sperm is selected by the embryologist without any specific testing.

Quite often this can be corrected with the administration of various hormones and other medication. Diagnosis and treatment, in up to 97 of cases a diagnosis can be made. In all cases there are treatment options available to suit the needs of a specific couple. With advancing technologies, such as pgs (pre-implantation genetic screening which minimizes the risk of recurrent failed ivf treatment and miscarriage, more and more patients can nowadays benefit from treatment. Treatment options include the following: dna Cycle monitoring, intra-uterine insemination, in vitro fertilization. Icsi, sperm and egg donation, surrogacy, cycle monitoring This involves frequent ultrasound scans to determine when an egg is ready to be released from the ovary. Once the follicle (structure housing an egg inside the ovary) has reached a certain size, the egg is then released from within the ovary and patients are then advised when to have intercourse. Treatment can either be in a natural cycle,.

They allow us to move in three dimensions, so that there will be one on the left to control the holding of the micropipette and puberty another to the right for the injection micropipette. In addition, there is an electric manipulator for large movements and an hydraulic one for the finest (adjustment of the pipettes is done with the hydraulic and quick movements to place them with the electric). They are hermetic syringes filled with mineral oil controlled by the micromanipulators and connected to the microinjection pipettes (to aspirate and inject the spermatozoa) by a flexible tube. It has voetbed to contain hydrogen to assure the optimal work conditions. 14 Procedure edit icsi is generally performed following a transvaginal oocyte retrieval procedure to extract one to several oocytes from a woman. In icsi ivf, the male partner or a donor provides a sperm sample on the same day when the eggs are collected. 15 The sample is checked in the lab, and if no sperm is present, doctors will extract sperm from the epididymis or testicle. The extraction of sperm from epididymis is also known as percutaneous epididymal sperm aspiration (pesa) and extraction of sperm from testicle is also known as testicular sperm aspiration (tesa).

Obstructive causes are characterized by a blockage of the vas epididimys, which is the tube responsible for the outflow of sperm directly from the testis. This can be as a result of previous infection, severe trauma to the testis and scrotal area, male sterilization (vasectomy) and genetical,. Absent vas in cases of Cystic Fibroses. This type of azoospermia has the best prognoses as in 95 of cases sperm can directly be obtained from the testis by means of a minor surgical procedure, also known as ssr (surgical sperm retrieval.). Non-obstructive causes imply that the vas epididimys is open; however the cells in the testis itself are not functioning correctly and as a result sperm are not being produced. In the majority of cases this is genetical in origin and the man has simply been born with abnormal / no cells responsible for the production of sperm. Secondary testicular failure is due to factors outside the testis, including hormonal causes, whereby there is no development of sperm.

As an investigation for causes of infertility, the benefit of performing a laparoscopy is indispensable. It gives a direct, 3-dimensional overview of the abdominal and pelvic structures and can confirm possible anatomical distortion of these structures and diagnose the presence of certain diseases including endometriosis. These conditions can also be treated at the same time and therefore the diagnostic benefit also becomes therapeutic at the same time with uwv no need to return for follow-up surgery at al later stage. Recurrent miscarriage screen, due to the complexity of this condition, there are various tests and investigations that need to be performed in order to diagnose, or exclude certain underlying contributory factors. Some of the basic investigations include blood tests, analyses of the immune system, excluding certain medical first conditions including genetic disorders and finally, evaluation of the uterus. Follow-up consultations, having completed various investigations, patients are then seen during a follow-up consultation to discuss the results to date, possible factors influencing their infertility and a diagnosis and appropriate treatment can be planned.

For all other patients who had already been through treatment at the practice a follow-up consultation is often recommended as it allows for a more in depth discussion about their situation and response. Female patients: Surgery, depending on the underlying condition, could potentially offer a good solution as it makes an improvement to the underlying cause of infertility in both the short and long term. However it should not be seen as a permanent cure for all conditions, as some conditions can return in due time,. The surgery itself can either be done with endoscopic procedures such as hysteroscopy and laparoscopy, or alternatively an open abdominal procedure called laparotomy. Surgery can be applied for various conditions including endometrioses, tubal problems, fibroids of the uterus, distortion of the normal pelvic anatomy, adhesions with scar tissue formation, etc. Male patients: azoospermia is the term given to men with no sperm in their ejaculate sample and this can be classified as primary or secondary testicular failure. Primary testicular failure is where the problem is directly in the testis and can be due to obstructive or non-obstructive causes.

Hysterosalpingogram (hsg x-ray this is a very useful investigation, which involves taking x/rays of the pelvic area in which the uterus and Follapian tubes can be assessed. Contrast dye is inserted through the uterine passage, which enables the cervical canal, uterine cavity and Follopian tubes to appear on the x/ray. The shape and outline of the uterine cavity can be assessed, and also the cervix and any malformations including cervical incompetence. Conditions such as a septum in the cavity, or fibroids and polyps can be diagnosed this way. As the dye passes through the left and right Fallopian tubes, not only can patency of the tubes be confirmed but can the rate at which the dye passes through give some indication of tubal function. This procedure is also performed by the gynaecologist together with the radiographer.

Hysteroscopy, this procedure evaluates the cervical and uterine cavity by using fibre optic scopes that are inserted through the vagina into the cervix. The picture is then transferred from the fibre optic lenses to a colour monitor where it can be viewed under direct vision. Surgery can be performed on the cervical or uterine cavity by means of hysteroscopy in which case it requires the patient to be asleep under general anaesthetic. Patients are therefore admitted to hospital and discharged a few hours after their procedure. Laparoscopy, this procedure involves a general anaesthetic and is performed as day-case surgery in a hospital. A fibre optic scope is inserted through the abdomen and with the aid of more instruments that are inserted through other ports (openings) in the abdomen; surgical procedures and evaluation of the female pelvic anatomy can be performed. Patients are admitted as a day-case at the hospital and discharged within a few hours following their surgery. Albeit the procedure is quite simple with very few risks, the technology nowadays makes it possible for skilled gynaecologists to do extensive pelvic surgery with very little post operative discomfort to patients.

Anti-sperm antibodies (immunological defects on the sperm that result in poor function of sperm.). Hormone tests on female patients, rubella immunity (female patients chromosome analyses are advised in certain cases of severe male factor infertility, though not routinely. It is also applicable in couples with recurrent miscarriage loss. It allows for direct vision of the uterus and ovaries and shows up abnormalities such as ovarian cysts, fibroids, large polyps inside the uterine cavity, etc. From a ieper fertility perspective it enables one to see the development of follicles inside the ovary, which is a fluid-filled structure in which a single egg is maturing. The ultrasound cannot identify the egg itself, as it is too small and can only be viewed under a microscope. However there is a similarity between the size of the follicle and the maturity of the egg and by measuring the follicles growth throughout the menstrual (treatment) cycle we online can conclude when an egg is ready to be released. Uss is also used to evaluate a pregnancy and give valuable information from an early stage. Pregnancy scans can normally be performed between 2 3 weeks after a positive pregnancy test.

Initial consultation, the discussion focuses on your fertility history, previous investigations and treatments. An examination is performed and most often also an ultrasound assessment. To assist with making a diagnosis and to determine the various factors that may contribute to your infertility, certain investigations are tanden performed which may include some of the following: Semen analyses, hormone and other blood tests on female patients and sometimes male patients. Ultrasound scans, hysterosalpingogram (HSG). Hysteroscopy, laparoscopy, recurrent miscarriage screen, investigations, semen analyses. An ejaculatory sperm sample is to be obtained and handed in for analyses by the scientists (andrologists). The four main factors that are analyzed include: Sperm count, morphology (appearance of the sperm motility (movement) of sperm and progression (speed at which the sperm moves.).

inverted microscopes are used that help embryologists to choose and pick an individual sperm for icsi ivf ) was a child in Singapore-born in April 1989. 5 The technique was developed by gianpiero palermo at the Vrije Universiteit Brussel, in the center for Reproductive medicine headed by paul devroey and Andre van Steirteghem. 6 The procedure itself was first performed in 1987, 7 though it only went to the pronuclear stage. 8 The first activated embryo by icsi was produced in 1990, 9 but the first successful birth by icsi took place on January 14, 1992 after an April 1991 10 conception. 11 Sharpe et al comment on the success of icsi since 1992 saying, "thus, the woman carries the treatment burden for male infertility, a fairly unique scenario in medical practice. Icsis success has effectively diverted attention from identifying what causes male infertility and focused research onto the female, to optimize the provision of eggs and a receptive endometrium, on which icsis success depends." 12 13 Laboratory equipment edit There are some requirements that an ivf. There are basically 5 main elements: laminar flow cabinet, inverted microscope, micromanipulators, microinjectors and anti-vibration table. It has to contain a hot surface and an environment with 5 of CO2. It should have 20X and 40X lens, with Hoffman optics, and a 37 C surface to have an optimal maintenance of the biological material.

Once fertilized, the egg is transformed into a proembryo and it has to be transferred to the uterus to continue its development. Defective sperm function remains the single most important cause of human infertility. 1, although certain severe forms of male infertility have a genetic origin, others may be the result of environmental factors. During the past decade, icsi has been applied increasingly around the world to alleviate problems of severe male infertility in human patients who either could not be assisted by conventional ivf procedures or could not be accepted for ivf because too few motile and morphologically. 2, the first human pregnancy generated by ics was carried out in 1991, by the hand. Gianpiero palermo and his team. Contents, indications schouder edit, schematic image of intracytoplasmic sperm injection in the context. This procedure is most commonly used to overcome male infertility problems, although it may also be used where eggs cannot easily be penetrated by sperm, and occasionally in addition to sperm donation. 3, it can be used in teratozoospermia, because once the egg is fertilized, abnormal sperm morphology does not appear to influence blastocyst development or blastocyst morphology.

What Is icsi, and How does It Differ From ivf?

Intracytoplasmic sperm injection icsi /ɪksi ik-see ) is an in vitro fertilization (IVF) procedure in which a single sperm cell is injected directly into niet the cytoplasm of an egg. This technique is used in order to prepare the gametes for the obtention of embryos that may be transferred to a maternal uterus. With this method acrosome reaction is skipped. There are several differences within classic ivf and icsi. However, the steps to be followed before and after insemination are the same. In terms of insemination, icsi needs one only sperm cell per oocyte, meanwhile ivf needs between 50 and 100 thousands. This is due to the fact that in ivf acrosome reaction has to take place and thousands of sperm cells have to be involved.
