The core of this method consists of facilitating the way of a sperm to the egg by injecting sperm, after special laboratory preparation, by means of a thin tube into the uterine cavity during the period of ovulation. The basic prerequisite for the application of this method is the preserved permeability of the Fallopian tubes. IUI can have a therapeutic effect in cases of disorders in male fertility, immunologically conditioned infertility and also in other indications.

Generally, an intrauterine insemination cycle starts with taking a medication to stimulate the ovaries. There are also ultrasounds to follow the development of the treatment and plan the date of insemination. Ovulation is initiated by medication and the insemination takes place 36 hours later. The day of the insemination, we perform an injection of the sperm, which has been washed to obtain the best quality sperm, into the uterus of the patient.

The first step would be to have a vasovasectomy to return fertility. If this intervention is successful, fertilisation can take place naturally or by insemination. If the reversal can not be performed, we can proceed with collecting sperm directly from the epidydimis or testicle with an aspiration technique. (PESA - TESA). However, the quantity recovered in this manner in not sufficient for intrauterine insemination, and only IVF is possible.

IUI is the use of husband or donor sperm to inseminate the uterus. The semen sample is washed, prepared and then placed into the uterus by passing a small plastic catheter through the cervix. This is an office procedure and is usually associated with no discomfort. The procedure places a large concentration of sperm into the upper uterus so the sperm are closer to the fallopian tubes where they can travel to fertilize an egg.

An intrauterine insemination consists of collecting a sample of sperm (or using the sperm of a donor) in order to inject the sperm directly into the uterus of the patient at the moment of ovulation. The fertilisation takes place in vivo, that’s to say in the body of the woman and not in the laboratory.

You will need to firstly undergo a reanastomosis, a surgery which can be performed in some cases, depending on which method was used to tie your tubes. This procedure is carried out in the hospital setting and is performed in certain hospitals only. Once this step is completed, pregnancy may be possible with natural methods or by insemination, depending on the results obtained.

IUI helps deliver much more motile sperm to the fallopian tubes at the critical times around ovulation, and is recommended to improve pregnancy rates in many instances, including: unexplained infertility; sperm issues (such as count, motility or morphology); when fertility medications (including Clomid or injectable medications) are being used; or when a cervical mucous abnormality blocks the ability of the sperm to swim in to the uterus.

Artificial insemination is now more commonly referred to as,IUI, Intrauterine insemination. It is a procedure used for couples with unexplained infertility, minimal male factor infertility, and women with cervical mucus problems. It is a procedure of using the husband's or donor sperm, washing and treating the sperm and injecting it into the woman during the time of ovulation. IUI

Artificial Insemination is allowed to be used as a breeding tool for animals that will be included in the Randall herdbook. The Registry encourages the use of live bulls to the extent possible as a means of increasing the number of sires used and thereby protecting the diversity of the gene pool. However AI can accomplish specific breeding objectives and may be the only option for breeders who are unable to keep a bull.

The number of straws required per insemination is determined by thawing a straw and rating its post thaw motility. For a frozen semen breeding you want to have a minimum of 100 million motile sperm per insemination. Each straw holds 50 million sperm but not all of them will survive the freezing process, hence the evaluation of "post thaw motility". The higher the percent post thaw motility the fewer straws are required.

Most doctors will do an intra-uterine insemination (IUI) the day after the LH surge, or about 36 hours after it is detected. With a vaginal insemination, or an intra-cervical insemination (ICI) in someone with good fertile mucus, the day of the surge may be preferable. Many doctors are now doing two inseminations per cycle. Check the IUI FAQ.

Insemination is a simple procedure, similar to a pelvic examination for PAP screening. Beyond simple discomfort, it is sometimes accompanied by mild uterine contractions (similar to menstrual pain), light staining and increased secretions.

Quality of the semen and timing of the bitch are key elements for success with using frozen semen. The largest litter we have had from a frozen semen insemination was a litter of 13 Irish Wolfhound puppies from semen that was frozen 10 years ago!

The insemination consists in placing the sperm preparation inside the uterus a few hours before the ovulation. The patient's doctor will establish the time of ovulation and subsequently evaluate the day when the insemination will take place. To do so, three methods are used: vaginal ultrasound, blood test and urine test. Stimulation with oral medicine or daily sub-coetaneous injections can be prescribed.

Today's breeding technology provides horse owners with more options than were available in the past. Artificial insemination and semen preservation techniques make it possible to ship stallion semen to mares nearly anywhere in the country. Success with transported semen will depend on the careful reproductive management of both stallion and mare. Only three registries do not currently allow AI: Thoroughbred, Miniature Horse, and Standard Jack and Jennet Registry.

Unlike fresh semen, which can live in the reproductive tract of a bitch for 5-7 days, frozen semen will only live 12-20 hours once thawed. It must preserve all it's energy to penetrate and fertilize the eggs, so the best conception rates (90% in our practice) are achieved with surgical insemination, where the semen is injected directly into the uterine horn. Since vaginal insemination has statistically low conception rates (under 20%), we do not suggest using your valuable semen in this fashion.
