If the procedure uses a donor, they will provide the sample will to a sperm bank. The staff at the facility then quarantines the sample and tests it for any transmittable diseases. The facility keeps the sperm frozen and thaws it out before making any preparations.
Before the freezing process, they add a chemical called cryptoprotectant that protects the sperm in cold storage.
During the procedure, the fertility doctor implants the sperm directly into the uterus with a fine catheter, keeping the vagina walls open using a speculum. The catheter enters the uterus through the cervix, and the doctor pushes the sperm through the catheter.
For the best results, IUI normally occurs very soon after ovulation. The ovaries have only just produced eggs, at fertility is at its highest during this point in the menstrual cycle. The doctor may give the woman an ovulation prediction kit OPK. This is a device that detects hormone levels in the urine or saliva, giving an accurate prediction of the ovulation date. The risk of conceiving twins or triplets increases if a woman receives IUI at the same time as other fertility medication, such as gonadotrophin.
A pregnancy with more than one fetus increases the chances of complications, such as premature birth or miscarriage. Nowadays, doctors only prescribe fertility medication when there are difficulties with ovulation, or producing the egg cells from which an embryo develops. It is rare, and symptoms are usually mild-to-moderate, but it can sometimes have serious complications.
In mild cases of OHSS, symptoms include bloating, slight abdominal pain, and possibly nausea and vomiting. More severe cases may feature dehydration , chest pain and shortness of breath. Staying hydrated and taking paracetamol normally alleviates the pain, but more severe cases may require hospital treatment. While IUI is less effective than more intensive procedures, such as in-vitro fertilization IVF , it has a 5 to 15 percent chance of success during the first insemination.
This chance dramatically increases by the sixth insemination for women who are less than 40 years of age, according to a study in a German clinic. In the study, the average number of cycles before a successful conception, or one that led to a live birth, was 2. However, doctors do not recommend more than six cycles of IUI, as the chance of a successful conception after the sixth cycle are very small. Doctors will prepare a semen sample — either from the intended father or a donor — by separating the sperm from the seminal fluid, says Tanmoy Mukherjee, M.
Next, the doctor will mix the sperm with liquid, load it onto a catheter, and insert it inside of the vagina.
When the catheter reaches the uterus, doctors will dispense the sperm inside. Mukherjee says the process resembles a Pap smear. Here are Dr. A simpler artificial insemination method, intracervical insemination ICI imitates natural intercourse. Unwashed, liquified semen from either a donor or the intended father is loaded into a syringe specially designed for ICI. Then it's inserted inside of the vagina and slowly emptied near the cervix.
A woman should lie on her back during the procedure and a half hour afterwards. If all goes well, the sperm will travel to the fallopian tubes and form a pregnancy. ICI can be conducted at home or a medical center. Washing the sperm may also increase effectiveness. Health insurance may cover some of the price, including extra expenses like blood work, ultrasounds, and medications.
Unwashed sperm contributes to the cheaper price tag — but you can also use washed sperm for a premium. Donor sperm also raises the cost of ICI. After multiple failed attempts, they may try in vitro fertilization IVF to conceive a child. Line up the gun with the cervix and pass it through the canal, manipulating the cervix back over the tip of the gun. The semen should be deposited into the short chamber of the uterine horns, which are located on the other side of the cervix.
If you put your index finger over the end of the cervix, you will feel where the top pokes through and this is the area where the semen should be deposited. It is where the cervix ends and the uterus begins.
Care should be taken to avoid placing the semen into just one horn. In addition, the walls of the uterus are extremely delicate and easily damaged. Be careful to avoid blocking off one of the horns; this can occur if the cervix is gripped too hard or a finger gets in the way. Do not reuse sheaths; splitting straws increases the risk of disease spread and can reduce pregnancy rates. Soiled insemination guns should be cleaned after use and treated with boiling water every few weeks.
Disinfectant can damage sperm. Keep the flask in a secure, well-ventilated area, replacing the stopper quickly to reduce liquid nitrogen loss. If it is necessary to bring the goblet up into the neck of the flask, then following a period of sec maximum, move the canister to the bottom of the flask for at least one minute to recool, before returning it to the neck. If the gun is placed incorrectly, pull it back slightly as it will probably have become caught in a fold.
In this event, the semen can be deposited in the cervix. Cervical insemination will reduce conception rate but so will inserting the AI gun too far up one horn; this may cause bleeding and trauma. Serving a pregnant cow carries the risk of breaking the cervical seal and calves can be lost this way.
The cause of this problem can be a failure to properly co-ordinate a breeding strategy with the vet. To maximise the potential benefits of AI, check the information on the straw and record all details of the insemination as soon as possible after the procedure.
