Recurrent implantation failure in IVF: features of cycles that eventually ended in conception.

PURPOSE: To evaluate the characteristics of patients and IVF cycles with recurrent implantation failure who eventually succeeded to conceive compared to those who failed to do so. METHODS: In a retrospective study, we explored our database for patients younger than 35 years old who underwent at least three unsuccessful fresh IVF cycles. The following parameters were analyzed: cause of infertility, FSH level, stimulation cycle characteristics, fertilization rate, the type of luteal support, and cycle outcome. Uterine cavity assessment was also included. The relationship between endometrial scratching and the outcome of the following IVF cycle was assessed for the subsequent pregnancy rate. RESULTS: The study included 184 patients who underwent 854 IVF cycles. There were no statistically significant differences between patients who eventually conceived and those who did not in terms of ovarian reserve and response to gonadotropin treatment. IVF cycles that eventually ended with conception were characterized by shorter stimulation (10.87 ± 2.17 versus 11.34 ± 2.33 days, p < 0.05), higher estrogen level on the day of hCG administration (1661 ± 667 versus 1472 ± 633 pg/ml, p = 0.009), more fertilized oocytes via ICSI (5.04 ± 4.29 versus 3.85 ± 3.45, p = 0.002), and more embryos available for transfer (5.98 ± 3.89 versus 5.12 ± 3.31, p = 0.002). Combined estrogen and progesterone luteal support combined with endometrial scratching prior to the subsequent IVF cycle has been positively related to increased pregnancy rates. CONCLUSIONS: Young patients with RIF having a normal ovarian reserve and satisfactory ovarian response to superovulation should be encouraged to pursue IVF, even though the probability to conceive is relatively low compared to the general IVF population.

Burning pain from chest to back · allodynia and hyperesthesia · extreme sensitivity at the left T5 dermatome · Dx?

A 27-year-old woman in the 21st week of her first pregnancy came to our clinic complaining of a constant burning pain that spread around her left chest wall to her back. She graded the pain as a 10 on a 0 to 10 visual analog scale. The pain, which began 3 months earlier, became worse when she took a deep breath, ate, or walked, but was alleviated by applying warm compresses. Our patient hadn't slept well since the pain began. Her medical history was noteworthy for chickenpox at age 5.
