Poor responder protocols for in-vitro fertilization: options and results.

PURPOSE OF REVIEW: To present the options and the results in the management of poor responders in in-vitro fertilization. RECENT FINDINGS: There is no controlled ovarian hyperstimulation protocol which is best suited for all poor responders. Low dose gonadotropin-releasing hormone agonist regimes appear to be most advantageous. Prediction of compromised response prior to cycle initiation by a thorough assessment of ovarian reserve as well as a careful review of past responses could allow for a more appropriate selection of a controlled ovarian hyperstimulation protocol for each individual patient. Optimistic data have been presented by the use of high doses of gonadotropins, flare up gonadotropin-releasing hormone agonist protocols (standard or microdose), stop protocols, luteal onset of gonadotropin-releasing hormone agonist, and short protocols. Natural cycle also seems to be an appropriate strategy to be considered. SUMMARY: There is no universal definition for the 'poor responder'. Numerous strategies have been proposed to improve ovarian stimulation in poor responders, but none of them is the ideal for all such patients. More data from good quality controlled trials are needed.

Luteal estrogen supplementation in stimulated cycles may improve the pregnancy rate in patients undergoing in vitro fertilization/intracytoplasmic sperm injection-embryo transfer.

OBJECTIVE: To evaluate the effect of estradiol addition to progesterone supplementation during the luteal phase on pregnancy and implantation rates in patients undergoing in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) cycles. METHODS: In this prospective, randomized study, carried out in an IVF unit of a university hospital, we studied patients who were undergoing IVF/ICSI with controlled ovarian hyperstimulation using a gonadotropin-releasing hormone agonist/human recombinant gonadotropin long protocol. The main outcome measures were the pregnancy and implantation rates measured in the two groups. RESULTS: Our results suggest higher pregnancy and implantation rates in IVF/ICSI-ET cycles that were supplemented with estradiol in the luteal phase. CONCLUSIONS: Estradiol supplementation during the luteal phase in women undergoing IVF/ICSI-ET has a beneficial effect on the outcome without (at least, as seems from this study) having any adverse effects.

Role of a bipolar resectoscope in subfertile women with submucous myomas and menstrual disorders.

AIM: To evaluate the role of the Gynecare (Ethicon, Somerville, NJ, USA) bipolar resectoscope in resecting fibroids, and the effect of hysteroscopic myomectomy on infertility and pregnancy outcomes. METHODS: From January 2000 to December 2005, we studied 59 women of reproductive age with menorrhagia, submucous myomas and one or more infertility factors. All women who participated had been subfertile for over 2 years. Fifteen of the 59 women displayed submucous myoma type O (intracavitary), 34 displayed submucous myoma type I (less than 50% within the myometrium) and the remaining 10 women displayed myoma type II (over 50% being within the myometrium). The mean age and standard deviation of these patients was 34.6 +/- 4.4 years and the average size of myomas was 15 +/- 10 mm. Treatment of these myomas was by hysteroscopic resection using a bipolar resectoscope. RESULTS: Menorrhagic incidents improved in 20 of 32 women (62.5%). Twenty-five women (42.4%) succeeded in becoming pregnant. The pregnancy rate was notably higher when the sole reason of subfertility was the presence of myoma (54.16%), and when the size of the myoma was equal to 2.5 cm (75%) or more. CONCLUSION: The use of the bipolar resectoscope in hysteroscopic removal of small submucous myomas is shown to be both feasible and effective in controlling menorrhagia and increasing the pregnancy rate in subfertile women, when submucous myomas are the only reason of infertility.
