Prediction of ovarian reserve based on day-3 serum follicle stimulating hormone concentrations during the pituitary suppression cycle using a gonadotropin releasing hormone agonist in patients undergoing in vitro fertilization-embryo transfer.

Satisfactory results following in vitro fertilization-embryo transfer (IVF-ET) treatments depend on retrieving an appropriate number of mature oocytes without causing the development of ovarian hyperstimulation syndrome (OHSS). The present study was carried out to investigate whether the ovarian reserve is predictable based on the day-3 serum concentration of follicle stimulating hormone (FSH) during the pituitary suppression cycle using a gonadotropin releasing hormone (GnRH) agonist (defined as day-3 FSH) in patients undergoing IVF-ET treatment. Day-3 FSH before the administration of gonadotropin was assessed in 72 IVF-ET cycles from 59 infertile women. The mean+/-SD of day-3 FSH, the total amount of FSH plus human menopausal gonadotropin (hMG) administered, and the total number of oocytes retrieved was 5.5+/-2.6 mIU/ml, 2834.2+/-1236.5 IU and 7.7+/-5.8, respectively. There were significant correlations between day-3 FSH and the total amount of FSH-hMG administered (p < 0.001), and day-3 FSH and total number of oocytes retrieved (p < 0.001). There was a significant difference of day-3 FSH between patients who subsequently conceived (4.4+/-1.3 mIU/ml) and those who did not conceive (6.1+/-2.9 mIU/ml) (p = 0.001). There was also a significant difference of day-3 FSH between patients who developed moderate or severe OHSS (4.5+/-1.2 mIU/ml) and those who did not (5.9+/-2.8 mIU/ml) (p = 0.003). Receiver-operator characteristic curve analysis showed that the significant cut-off point for day-3 FSH for predicting ovarian reserve was 5.25 mIU/ml. These findings indicate that day 3-FSH is usefulfor predicting ovarian reserve during the pituitary suppression cycle using a GnRH agonist in patients undergoing IVF-ET.     

Prediction of ovarian reserve based on day-3 serum follicle stimulating hormone concentrations during the pituitary suppression cycle using a gonadotropin releasing hormone agonist in patients undergoing in vitro fertilization–embryo transfer

Satisfactory results following in vitro fertilization–embryo transfer (IVF-ET) treatments depend on retrieving an appropriate number of mature oocytes without causing the development of ovarian hyperstimulation syndrome (OHSS). The present study was carried out to investigate whether the ovarian reserve is predictable based on the day-3 serum concentration of follicle stimulating hormone (FSH) during the pituitary suppression cycle using a gonadotropin releasing hormone (GnRH) agonist (defined as day-3 FSH) in patients undergoing IVF-ET treatment. Day-3 FSH before the administration of gonadotropin was assessed in 72 IVF-ET cycles from 59 infertile women. The mean?±?SD of day-3 FSH, the total amount of FSH plus human menopausal gonadotropin (hMG) administered, and the total number of oocytes retrieved was 5.5?±?2.6 mIU/ml, 2834.2?±?1236.5?IU and 7.7?±?5.8, respectively. There were significant correlations between day-3 FSH and the total amount of FSH–hMG administered (p?<?0.001), and day-3 FSH and total number of oocytes retrieved (p?<?0.001). There was a significant difference of day-3 FSH between patients who subsequently conceived (4.4?±?1.3 mIU/ml) and those who did not conceive (6.1?±?2.9 mIU/ml) (p?= 0.001). There was also a significant difference of day-3 FSH between patients who developed moderate or severe OHSS (4.5?±?1.2 mIU/ml) and those who did not (5.9?±?2.8 mIU/ml) (p?=?0.003). Receiver-operator characteristic curve analysis showed that the significant cut-off point for day-3 FSH for predicting ovarian reserve was 5.25?mIU/ml. These findings indicate that day 3-FSH is useful for predicting ovarian reserve during the pituitary suppression cycle using a GnRH agonist in patients undergoing IVF-ET.

Predicting poor ovarian response in IVF: use of repeat basal FSH measurement

OBJECTIVE: To evaluate the additional value of a second basal follicle stimulating hormone (FSH) level, in a different cycle, in the prediction of poor response in in vitro fertilization (IVF) by a single basal FSH measurement. STUDY DESIGN: In 120 patients, basal FSH was determined prospectively in 2 spontaneous cycles. The additional value of a second basal FSH measurement in the prediction of poor ovarian response in IVF by a single basal FSH measurement was studied. RESULTS: Due to chance variation, the predictive accuracy of a poor response of the first and second basal FSH measurement differed (ROC(AUC) .84 and .74, respectively). In a multivariate analysis, the higher of the first and second basal FSH levels provided the best predictive accuracy (ROC(AUC) .85). In terms of clinical relevance, however, a predictive model with the highest basal FSH level provided only slightly more correct predictions of poor and normal ovarian response than did models based solely on a single basal FSH measurement. CONCLUSION: Using basal FSH, a substantial number of patients will be misdiagnosed with regard to their ovarian response potential in IVF, even if repeat measurement is performed.     

Natural cycle as first approach in aged patients with elevated follicle-stimulating hormone undergoing intracytoplasmic sperm injection: a pilot study.

BACKGROUND: Poor ovarian response to standard in vitro fertilization-embryo transfer (IVF-ET) protocols or different regimens of treatment, as consequence of a diminished ovarian reserve, correlates strictly with patient age, elevated follicle-stimulating hormone (FSH) and reduced antral follicle count. The aim of the present pilot study was to evaluate the outcome of patients with poor prognostic features undergoing IVF-ET with natural cycles as a first approach and not as a consequence of a previous failure treatment. MATERIALS AND METHODS: Eighteen aged patients (mean +/- standard deviation 40.2 +/- 0.7 years, range 37-43 years) with elevated serum FSH and reduced antral follicle count underwent intracytoplasmic sperm injection (ICSI) after spontaneous ovulation. RESULTS: A total of 26 natural cycles with ICSI were analyzed. Pregnancy was observed in three patients, of which two were ongoing as assessed by fetal heart beat at ultrasound scan performed 4-5 weeks after ET. CONCLUSION: The overall pregnancy rates achieved (11.5% per cycle, 20.0% per ET) are comparable with those of conventional IVF-ET in aged patients, and not impaired by a single embryo transferred. Better embryo quality, as a consequence of natural selection of oocytes, better endometrium receptivity and monthly repeatability of the procedure, can balance the relatively low chance to perform ET.
