The ICMART glossary on ART terminology.

The International Committee Monitoring Assisted Reproductive Technologies (ICMART) is an independent, international non-profit organization that has taken a leading role in the development, collection and dissemination of worldwide data on ART. Information on availability, efficacy and safety is provided to health professionals, health authorities and the public. The glossary facilitates dissemination of ART data through a set of agreed definitions as seen in the most recent World Report on ART. It provides a conceptual framework for further international terminology and data development of ART.

World collaborative report on in vitro fertilization, 2000.

The International Committee for Monitoring Assisted Reproductive Technology's 7th World Report for the year 2000 analyzes wide variations in live and multiple birth rates from 49 countries and six regions by type of assisted reproductive technology, age, number of embryos transferred, and multiple births. More than 460,157 procedures resulted in delivery rate per aspiration for conventional in vitro fertilization (IVF) of 18.6%; for intracytoplasmic sperm injection (ICSI), 20.4%; for egg donation, 32.3% per transfer; and for frozen ET, 12.0% per transfer. Conventional IVF and ICSI twin rates were 26.9% and 26.2%, respectively, and triplet rates were 2.8% and 2.9%, respectively, for an estimated total of approximately 197,000 to 220,000 babies worldwide.

Clomiphene citrate challenge test predicts outcome of intrauterine insemination in women aged under 37 years.

The clomiphene citrate challenge test is a tool to predict ovarian reserve and fertility. It has mainly been used as a predictor of success of IVF/intracytoplasmic sperm injection (ICSI) cycles. Infertile young women with diminished ovarian reserve have a worse prognosis than women with adequate ovarian reserve attempting IVF/ICSI cycles. Nothing is known regarding the outcome of young women with diminished ovarian reserve undergoing low-complexity assisted reproductive treatment such as ovulation induction plus intrauterine insemination (IUI). This study included all women under 37 years who consulted in the authors' centre between May 2004 and August 2005 who underwent ovulation induction and IUI. Ninety-six women younger than 37 years with adequate ovarian reserve, and 50 women with diminished ovarian reserve were found. The pregnancy rate and pregnancy rate per cycle in the adequate ovarian reserve group were significantly higher than those of the diminished ovarian reserve group (46.7% versus 25%, P < 0.02 ; 15.9% versus 7.6%, P < 0.02 respectively). It is concluded that the clomiphene citrate challenge test is a good predictor of low-complexity infertility intervention outcome, and represents an effective tool to establish a prognosis. Therefore, it is very useful in planning therapy, and advising the infertile couple.

The cesarean delivery scar pouch: clinical implications and diagnostic correlation between transvaginal sonography and hysteroscopy.

OBJECTIVE: We sought (1) to describe an anatomic defect of the uterine cavity in the anterior isthmus diagnosed by transvaginal sonography in a group of premenopausal women with previous cesarean deliveries, (2) to establish whether there is an association between the presence of the pouch and a bleeding disturbance, and (3) to compare the diagnostic efficacy of transvaginal sonography versus hysteroscopy for the detection of this defect. METHODS: We performed a retrospective study of 92 premenopausal women with histories of at least 1 cesarean delivery. Age, number of previous cesarean deliveries, time elapsed between last cesarean delivery and first consultation, and total area of the pouch were recorded in groups of women with and without abnormal bleeding. Hysteroscopy was also performed in 43.8% of the patients who had abnormal bleeding. RESULTS: In all women, transvaginal sonography revealed the presence of a pouch on the anterior uterine segment at the site of the expected previous cesarean delivery scar. Hysteroscopy showed 100% correlation with transvaginal sonography in detection of this pouch. CONCLUSIONS: The high correlation between bleeding disturbances and the presence of a pouch, in the absence of other pathologic entities, suggests this anatomic defect as the possible cause, especially in view of the fact that women who had heavier and longer bleeding episodes tended to have a larger pouch. Transvaginal sonography is a very simple, noninvasive, low-cost examination that should be considered as the first choice for screening, because it highly correlates (100%) with hysteroscopy in the diagnosis of this defect and may help rule out other causes.
