Background: Due to the seasonality reproduction of albino hamster (April to October in the Northern Hemisphere) and the need to produce blastocysts for research applications, producing and collecting blastocysts by natural mating in non-breeding season is complex in this species. In the present study in vivo blastocysts production and collection using super-ovulation and intrauterine inseminati...

OBJECTIVE To compare the outcomes of single versus double intrauterine insemination. MATERIALS AND METHODS This prospective randomized study was carried out in 100 infertile patients. One intrauterine insemination was applied 36 hours after human chorionic gonadotropin (hCG) injection to 50 patients in the first group. To 50 patients in the second group, two intrauterine inseminations were ap...

In all domestic species, acceptable pregnancy rates with frozen-thawed semen are only achievable with intrauterine insemination. Unlike the cow and the goat, the cervix of the ewe is a formidable barrier to penetration for transcervical intrauterine insemination not only due to the physical size of the canal and a narrow luminal diameter (even at estrus), but also due to it’s caudally facing, e...

In an experiment involving the artificial insemination of 312 Merino ewes, fertilization, early (18 day), and late (100 day) pregnancy rates were examined after intrauterine insemination with frozen semen using a laparoscope. Oestrus was synchronized in ewes by progestagen sponge/PMSG treatment. After cervical insemination of fresh semen (control) 55 hrs after sponge removal, the fertilization,...

Intrauterine insemination is a common procedure used for the treatment of different causes of infertility. Adverse reactions associated with this procedure are very rare and usually the procedure is well tolerated by the patient. We report a case of an allergic reaction after intrauterine insemination. The patient developed fever, difficulty breathing and wheezing in both lung fields. Although ...

The objective of this study was to determine the clinical pregnancy rate with 2 inseminations compared to a single intrauterine insemination (IUI) in a given cycle using frozen-thawed donor sperm. This was a retrospective study at a university practice; patients were women using donor sperm. We conducted a comparison of single IUI, intracervical insemination (ICI) followed by an IUI on the...

Adult East Freisan crossbred (n = 220) and Chios ewes (n = 105) were divided into four groups and inseminated with chilled semen, which had been stored for 7, 13, 20 or 26 h at 5°C. Unilateral intrauterine insemination (50 x 10 6 spermatozoa in 0.25 ml) was performed with the aid of a laparoscope. Inseminations were carried out 48 – 52 h after pessary removal (30 mg FGA) without detecting estru...

Stimulated intrauterine insemination (IUI) should be the first choice treatment for mild male factor infertility, unexplained infertility or minimal to mild endometriosis. In mild male factor infertility, unexplained infertility, IUI is as effective as IVF & at 1/3 of the cost per pregnancy. In couples with the most severe semen defects, IUI in natural cycle should be the treatment of choice. I...

To explore the related factors on the clinical pregnancy outcome in intrauterine insemination, a retrospective study was conducted on the clinical data of 580 cycles for 301 infertile couples who were treated with intrauterine insemination. The female age, male age, duration of infertility, treatment protocols, endometrial thickness and sperm parameters were compared between pregnant group and ...

OBJECTIVE We evaluated the efficacy of fresh versus frozen sperm in therapeutic donor insemination. STUDY DESIGN Fifty-seven women underwent 72 courses of treatment (a maximum of six therapeutic donor insemination cycles--three fresh and three frozen) totaling 198 cycles. Each woman served as her own control and was prospectively randomized to receive a single, timed insemination of either fr...
