Excisional surgery versus ablative surgery for ovarian endometrioma.

Background: Endometrioma are endometriotic deposits within the ovary. Laparoscopic management of endometriomas is associated with shorter hospital stay, faster recovery, and decreased hospital costs compared with laparotomy. The previous version of this systematic review (2008), including randomised controlled trials (RCTs) of surgical interventions for endometrioma, concluded that laparoscopic cystectomy (excision) was preferable to drainage and ablation of endometrioma.

Dopamine agonists for preventing ovarian hyperstimulation syndrome.

Background: Ovarian hyperstimulation syndrome (OHSS) is a potentially serious complication of ovarian stimulation in assisted reproduction technology (ART). It is characterised by enlarged ovaries and an acute fluid shift from the intravascular space to the third space, resulting in bloating, increased risk of venous thromboembolism, and decreased organ perfusion. Most cases are mild, but forms of moderate or severe OHSS appear in 3% to 8% of in vitro fertilisation (IVF) cycles.

Endometrial preparation for women undergoing embryo transfer with frozen embryos or embryos derived from donor oocytes.

Background: A frozen embryo transfer (FET) cycle is when one or more embryos (frozen during a previous treatment cycle) are thawed and transferred to the uterus. Some women undergo fresh embryo transfer (ET) cycles with embryos derived from donated oocytes. In both situations, the endometrium is primed with oestrogen and progestogen in different doses and routes of administration.
