Combined progesterone (IM + V) versus vaginal progesterone for luteal support in cleavage-stage embryo transfer cycles of good prognosis patients.

Many reports led to the consensus on the use of progesterone (P) for luteal-phase support. Vaginal P application is the method of choice due to its simplicity and high patient convenience but is hampered by application difficulties and personal or cultural aversions. Inappropriate vaginal P use may alter successful implantation, leading physicians to consider alternate P application routes. A worldwide survey revealed that intramuscular plus vaginal P (combined P) is the method used in nearly one-third of in vitro fertilization (IVF) cycles, particularly in Asia and North America; unfortunately, the outcomes of this approach have not been clearly elucidated. In the current analysis, we evaluated any additional benefit of short course parenteral P in addition to vaginal P capsules during a specific period in terms of implantation, pregnancy rates, miscarriages and ectopic pregnancies in cleavage stage embryo transfer (ET) cycles of good-prognosis patients. Despite significantly higher implantation rates in the combined arm, clinical and ongoing pregnancies were comparable in both groups, whereas a trend toward increased pregnancy rates was observed with combined support. The available data are too limited to draw conclusions.

Analysis of uterine and ovarian arterial blood flow and ovarian hormone levels prior to and after hysteroscopic endometrial resection.

The objective of this study was to evaluate the effect of hysteroscopic endometrial ablation on the ovarian and uterine artery blood flow and on follicle stimulating hormone (FSH) and oestradiol (E2) levels. A total of 26 consecutive women with abnormal uterine bleeding refractory to medical treatment had undergone hysteroscopic electrosurgical transcervical resection of the endometrium (TCRE). Ultrasonographic measurement of ovarian volumes and colour Doppler flow assessment of the uterine and ovarian arteries were performed on all patients before surgery (group 1) and 1 week (group 2) and 6 months (group 3) after surgery. Blood samples were also collected for determination of FSH and E2 levels, 4 weeks before and 1 month after surgery. No statistically significant change was observed between preoperative and postoperative (1st week and 3rd month) volumes of the ovaries. The mean pulsatility index (PI) of the uterine and ovarian artery did not show statistically significant differences between postoperative 1st week and 3rd month measurements of uterine and ovarian artery PI. The increase in serum levels of FSH and E2 after endometrial resection did not reach statistical significance. Although, women may present with climacteric complaints of hot flushes and nocturnal sweating after endometrial resection, this is probably a psychological response to hypomenorrhoea and amenorrhoea, as no statistically significant changes in FSH and E2 levels and uterine/ovarian blood flow were demonstrated in the early postoperative period.

Recurrent partial hydatidiform mole: a report of a patient with three consecutive molar pregnancies.

Hydatidiform mole (HM) is the most common form of gestational trophoblastic neoplasia and is characterized by atypical hyperplastic trophoblasts and hydropic villi. Recurrence of HM is extremely rare. Here, we report the case of a patient with three consecutive partial HMs without normal pregnancy. A 28-year-old woman with gravida 3, para 0, was referred to our hospital with a diagnosis of an invasive mole in December 2003. She had three consecutive molar pregnancies in 2000, 2001, and 2003. All three molar pregnancies were evacuated by suction curettage and the patient was followed by serial beta-human chorionic gonadotropin levels. All three moles were histologically confirmed as partial moles. In the first two molar events no additional treatment after evacuation was required, but in the last event, the beta-human chorionic gonadotropin levels increased and an invasive mole was suspected. Diagnostic workup ruled out an invasive mole and choriocarcinoma. Karyotypic analysis of the patient and her husband was normal. The patient required chemotherapy for treatment of persistent disease. Recurrent partial HM is a very rare clinical disorder. Repetitive molar pregnancy is not an indication for chemotherapy, but persistent disease does require chemotherapy.

The effect of the levonorgestrel intrauterine system on uterine artery blood flow 1 year after insertion.

OBJECTIVE: To assess whether the morphological alterations of the endometrium induced by the levonorgestrel intrauterine system affect the uterine artery vasculature. METHODS: Forty-eight premenopausal women attending our gynecology clinic because of menorrhagia were enrolled into the study. Clinical measures of menstrual bleeding, endometrial thickness and Doppler flow of the uterine artery (resistance (RI) and pulsatility (PI) indices) were evaluated before and 1 year after insertion of the levonorgestrel intrauterine system. Thirty-three (69%) women were available for re-evaluation at the end of the first year and the continuation rate was 76% (n = 25). A paired samples t-test and the Mann-Whitney U-test were used for comparison of values between groups. RESULTS: The mean age of the thirty-three patients was 44.3 +/- 7.6 years. Nine patients (27.3%) were amenorrheic and three patients were in menopause at the end of the year. After excluding the women in menopause, the increase in mean RI 1 year after insertion was statistically significant (0.86 +/- 0.07 vs. 0.81 +/- 0.08; P = 0.046), as was the decrease in uterine volume (736.9 +/- 276.9 mL vs. 972.75 +/- 465.71 mL; P = 0.029). The mean endometrial thickness decreased 1 year after insertion, but not significantly (4.6 +/- 1.6 mm vs. 6.6 +/- 3.5 mm; P = 0.07) and there was no statistically significant difference in mean PI between the groups (2.00 +/- 0.63 and 2.03 +/- 0.64 pre- and post-insertion, respectively; P = 0.83). CONCLUSION: The increase in mean RI of the uterine artery and the decrease in uterine volume 1 year after insertion of the levonorgestrel intrauterine system may be related to its progestational effect. This increase in RI may have a role in cessation of menstruation.
