Artificial insemination with the partner's sperm (AIH)

IntrauterineWithin the uterine cavity. inseminationProcess to facilitate the meeting of spermatozoon and oocyte (egg). Using a catheter, semen prepared for this purpose is brought directly into the uterus. (IUI) with the partner's spermEjaculated spermatozoa and secretions during the male orgasm. is generally the first treatment proposed when the spermEjaculated spermatozoa and secretions during the male orgasm. or the cervical mucusMucous secretion of the cervix of the uterus, through which the migration of spermatozoa into the uterus and fallopian tubes occurs. The amount and consistency of cervical mucus changes at the time of ovulation to allow sperm access to the fallopian tubes where fertilization of the egg takes place. are the cause of subfertilityReduced fertility..

Medical indications for IUI: pathological spermEjaculated spermatozoa and secretions during the male orgasm.-mucus compatibility test, unexplained infertilityDifficulty for a man or a woman to procreate as a result of a functional disorder or an organic lesion of the reproductive system, generally acknowledged after one year of regular, unprotected sexual relations. of more than 2 years, decreased semen volume or a reduced number, mobility and / or morphologyShape, conformation. of the spermatozoa (male factor, known as the oligo-terato-asthenozoospermiaReduction in sperm motility. Sperm are either stationary or slower than normal sperm. syndrome  (OTA)).

Ovarian stimulationMedical treatment designed to stimulate the ovaries, the follicular growth and development. This treatment usually allows several oocytes to become mature. may be associated with the inseminations with the partner's spermEjaculated spermatozoa and secretions during the male orgasm. (AIH). This allows to solve some hormonal problems and is intended to restore ovulationThe release of the egg from the ovary. A mature follicle bursts, expelling the egg it contains into the fallopian tube. This usually occurs around the middle of the menstrual cycle. or to increase the number of follicles reaching maturity. It also supports the preparation of the endometriumMucous membrane of the inner wall of the uterus. During the menstrual cycle, the uterine lining builds up to the time of ovulation. If fertilization occurs, the egg may implant in the uterus, otherwise, the periods appear. The mucosa which had thickened for the implantation of the fertilized egg degenerates and is expelled from the uterus in the form of bleeding. for embryoTerm designating the early stages of development from conception to the eighth week of pregnancy. From the first cell division on, the two-cell stage, one uses the term embryo. implantationInstallation of the embryo in the uterine lining.. StimulationOvarian stimulation. Medical treatment designed to stimulate the ovaries, the follicular growth and development. This treatment usually allows several oocytes to become mature. involves drugs such as clomiphene citrate, or injections of hormonesSubstances secreted by the endocrine glands. Hormones act as chemical messengers for regulating metabolic processes throughout the body. (follicleFluid-filled sac in the ovary containing and nourishing the egg during its maturation. During ovulation, the follicle bursts and releases the egg. stimulating hormone, FSHFollicle stimulating hormone. Hormone secreted by the pituitary stimulating in the woman the growth of follicles inside the ovary and in the man the development of spermatozoa., luteinizing hormone, LHLuteinizing hormone. Hormone secreted by the pituitary gland, triggering on the one hand the expulsion of the ovum by the mature follicle and stimulating on the other hand the production of progesterone by the corpus luteum.; pregnancy hormone, HCGHuman chorionic gonadotropin. Hormone produced by the placenta during pregnancy. It causes the secretion of estrogen and progesterone by the corpus luteum to support the growth of the uterine lining. It also prevents menstruation in the first days of pregnancy.). 
 These injections are given subcutaneously, usually by the patient herself or her partner. In all cases, after the StimulationOvarian stimulation. Medical treatment designed to stimulate the ovaries, the follicular growth and development. This treatment usually allows several oocytes to become mature. is initiated, ultrasound scans will allow the doctor to ensure that the ovarian response is controlled and the risk of a multiple pregnancy is within acceptable limits.

The optimal time for inseminationProcess to facilitate the meeting of spermatozoon and oocyte (egg). Using a catheter, semen prepared for this purpose is brought directly into the uterus. is determined by testing hormonesSubstances secreted by the endocrine glands. Hormones act as chemical messengers for regulating metabolic processes throughout the body. in the blood, by one or more vaginalRelating to the vagina. ultrasounds or qualitative LHLuteinizing hormone. Hormone secreted by the pituitary gland, triggering on the one hand the expulsion of the ovum by the mature follicle and stimulating on the other hand the production of progesterone by the corpus luteum. tests in the morning urine. Once the date and time of inseminationProcess to facilitate the meeting of spermatozoon and oocyte (egg). Using a catheter, semen prepared for this purpose is brought directly into the uterus. have been set by the physician in charge, the FERTAS laboratory gives an appointment to the partner for spermEjaculated spermatozoa and secretions during the male orgasm. collection (obtained by masturbation) one to two hours before the planned inseminationProcess to facilitate the meeting of spermatozoon and oocyte (egg). Using a catheter, semen prepared for this purpose is brought directly into the uterus.. The semen is to be prepared in the laboratory by detecting the motile spermEjaculated spermatozoa and secretions during the male orgasm. and eliminating the seminal fluid. The inseminationProcess to facilitate the meeting of spermatozoon and oocyte (egg). Using a catheter, semen prepared for this purpose is brought directly into the uterus. is performed at the CPMA by the physician in charge and consists of introducing the suspension of spermatozoa into the uterusPear-shaped organ that contains and nourishes the fetus during pregnancy, which contracts in a powerful and rhythmic manner at birth to expel the fetus. using a flexible catheterSmall tube that can be inserted into organs., while the patient is in the classical gynecological position. This medical procedure is painless.

The patient can perform a urinary pregnancy test 14 days after the inseminationProcess to facilitate the meeting of spermatozoon and oocyte (egg). Using a catheter, semen prepared for this purpose is brought directly into the uterus. . She will then communicate the positive or negative result by telephone to the CPMA in order to receive further instructions.
