Article: Low-molecular-weight heparin in the treatment of recurrent IVF-ET failure and thrombophilia: a prospective randomized placebo-controlled trial.
[show abstract] [hide abstract]
ABSTRACT: Recently, thrombophilia (acquired and inherited) has been implicated in recurrent IVF-ET failure. The objective of this study was to determine the effect and safety of thromboprophylaxis using low-molecular-weight heparin (LMWH) in women with recurrent in vitro fertilization (IVF)-embryo transfer (ET) failure and thrombophilia. Eighty-three women with history of three or more previous IVF failures and who had at least one thrombophilic defect were eligible for this study. Patients were randomly allocated into two groups: Group A (n = 42) received enoxaparin 40 mg/day, and group B (n = 41) received placebo (NaCl 0.9%). Both treatments started on the day of ET and continued until delivery or foetal demise was diagnosed. The primary outcomes were the implantation, pregnancy and live birth rates. Patients who received LMWH for thromboprophylaxis had a significant increase in the implantation and pregnancy rates compared with the placebo group (20.9% vs. 6.1% and 31% vs. 9.6%, respectively; p < 0.001 and p < 0.05, respectively). A significant increase in the live birth rate was observed in the heparin-treated group compared with placebo (23.8% vs. 2.8%, respectively; p < 0.05). The abortion rate was significantly higher in the placebo-treated group compared to the heparin-treated group (p < 0.05). The frequency of treatment complications did not differ between the two study groups. LMWH is a safe and effective thromboprophylactic treatment for women with thrombophilia and recurrent IVF-ET failures. The implantation rate, pregnancy and live birth rates are significantly increased with such treatment.Human Fertility 12/2008; 11(4):246-53. · 1.38 Impact Factor -
Article: Luteal phase support with GnRH-a improves implantation and pregnancy rates in IVF cycles with endometrium of <or=7 mm on day of egg retrieval.
[show abstract] [hide abstract]
ABSTRACT: The objective of this study was to examine the use of gonadotrophin-releasing hormone agonist (GnRH-a) for luteal phase in a group of patients with thin endometrium (<or=7 mm) after IVF treatment. One-hundred-and-twenty women were eligible for this study. Patients were randomly allocated into two groups: group A (n = 60) received triptorelin 0.1 mg on the day of ovum pickup (OPU), on the day of embryo transfer (ET) and three days thereafter, and group B (n = 60) received placebo. The primary outcomes were implantation and pregnancy rates. Although there was no significant difference in the number of good quality embryos transferred in both groups, the implantation and pregnancy rate were significantly higher in the GnRH-a - treated group compared with placebo controls. Furthermore, Estradiol (E(2)), progesterone (P) levels and endometrial thickness were significantly more elevated in patients who received GnRH-a for luteal phase support. The administration of GnRH-a at the time of OPU significantly improves the implantation and pregnancy rates in patients with thin endometrium (<or=7 mm).Human Fertility 04/2008; 11(1):43-7. · 1.38 Impact Factor -
Article: Luteinized unruptured follicle syndrome: incidence and recurrence rate in infertile women with unexplained infertility undergoing intrauterine insemination.
[show abstract] [hide abstract]
ABSTRACT: The objective of this study was to determine the incidence and recurrence rate of luteinized unruptured follicle (LUF) syndrome in women with unexplained infertility undergoing intrauterine insemination (IUI). A total of 167 women with unexplained infertility who underwent 292 cycles of IUI were enrolled in the study. All patients were treated with clomiphene citrate, 50-150 mg/daily from day 5 to 9 of their menstrual cycle. Ultrasound examination to confirm ovulation was performed on the day of IUI (day 0) and every day thereafter for another 3 days (days 1, 2 and 3). A total of 69 women who failed to conceive in the first cycle and 56 women who failed to conceive in the second cycle underwent second and third cycles, respectively. Of the total 167 patients who underwent first cycle, 42 (25%) had LUF. The incidence of LUF was 56.5% in 69 patients who underwent a second cycle of IUI treatment, of whom 33 patients had LUF in the first cycle with recurrence rate of 78.6%. In 56 patients who underwent 3 consecutive cycles, the incidence of LUF was 58.9% and recurrence rate of 90%. No pregnancies were recorded in patients with LUF during the study period. The incidence and recurrence rate of LUF are significantly increased in subsequent cycles of IUI. In these patients, other options of infertility treatment might be justified.Human Reproduction 09/2006; 21(8):2110-3. · 4.47 Impact Factor
