Contemporary Management of Unexplained Infertility.

Infertility is estimated to affect about 10% to 15% of couples. Most cases of infertility have etiologies that can be attributed to tubal factors, ovulatory dysfunction, endometriosis, uterine factor, male factor, or diminished ovarian reserve, while the remainder often do not have a known attributable cause, that is, unexplained infertility. The current manuscript summarizes the contemporary management of unexplained infertility.

Role of NOD2 in antiphospholipid antibody-induced and bacterial MDP amplification of trophoblast inflammation.

Women with antiphospholipid antibodies (aPL) are at high risk for pregnancy complications, such as preeclampsia. We previously demonstrated that aPL recognizing βGPI promote an extravillous trophoblast pro-inflammatory, anti-migratory and anti-angiogenic profile similar to that seen in preeclampsia. Since preeclampsia in the absence of aPL may have an underlying infectious element, women with aPL may be at increased risk for preeclampsia or other adverse outcomes if an infection is present.

Combined GnRH-agonist and human chorionic gonadotropin trigger improves ICSI cycle outcomes in patients with history of poor fertilization.

Purpose: The purpose of this study was to investigate the utility of a combined GnRH-agonist (GnRH-a) and human chorionic gonadotropin (hCG) trigger in improving ICSI cycle outcomes in patients with poor fertilization history after standard hCG trigger in prior ICSI cycles.

Methods: Retrospective cohort study. Patients with a fertilization rate of <20% in at least two prior ICSI cycles who subsequently underwent another ICSI cycle with hCG trigger were compared to those who underwent another ICSI cycle with a combined GnRH-a and hCG trigger.

A series of malignant ovarian cancers arising from within a mature cystic teratoma: a single institution experience.

Background: Mature cystic teratoma (MCT) is the most common germ cell tumor. It accounts for 10% to 20% of all ovarian masses. The likelihood of malignancy arising from within an MCT is low, and prognosis is poor.

Past, present and future targets for immunotherapy in ovarian cancer.

Ovarian cancer is the leading cause of death from gynecologic malignancy in the US. Treatments have improved with conventional cytotoxic chemotherapy and advanced surgical techniques but disease recurrence is common and fatal in nearly all cases. Current evidence suggests that the immune system and its ability to recognize and eliminate microscopic disease is paramount in preventing recurrence.

An unexpected mass of the urachus: a case report.

The urachus is a remnant of the urogenital sinus and allantois, which persists after antenatal involution. Despite its rudimentary postnatal presence, it can undergo metaplasia and tumor formation. Malignant transformation of the urachus is rare.
