Insemination (IUI)

Σπερματέγχυση (IUI)


Insemination is a rather simple infertility treatment during which suitably processed and prepared sperm is placed with a catheter directly into the endometrial cavity on the day of ovulation. The purpose of insemination is to maximize the number of sperm reaching the woman's fallopian tubes and hence increase the chance of fertilizing the egg. The fertilization is achieved naturally, without any interference.

Therefore, if you are interested in an assisted reproductive method, insemination can be your first choice, since it is much easier and less costly than the in vitro fertilization process.


Insemination can be applied to couples with unexplained infertility, ovulation disorders, in low and mild endometriosis, in mild male infertility, in women with cervical mucus problems, as well as immune-induced infertility. Insemination provides the sperm with an advantage, giving it a lead but still requires a good quality of sperm to be able to reach and fertilize the egg by itself.


Insemination is performed on the ovulation day. The sperm sample will undergo full testing and suitable processing from the laboratory, in order to separate sperm and seminal fluid. After the sample is processed, with the help of a flexible plastic catheter, endometrial infusion of a small amount of sperm (0.5 ml) containing sperm with the highest mobility. In cases of male azoospermia, insemination can also be performed using donor sperm. 

Insemination usually takes a little time and is usually painless. The wife should remain relaxed and calm for a small amount of time, in order to avoid any uterine contractions and semen excretion. Then the couple can return to their home. You will be able to do a pregnancy test about two weeks later.


The success rates depend on the infertility problem as well as the age of the couple. Most couples that choose insemination have 15% to 18% chance of success in every cycle. The chance of success increases to about 25%, when insemination is combined with fertility medications.
