OHSS has been characterized by the presence of multiple luteinized cysts within the ovaries leading to ovarian enlargement and secondary complications, but that definition includes almost all women undergoing ovarian stimulation. The central feature of clinically significant OHSS is the development of vascular hyperpermeability and the ...
While serious complications are possible, "the majority of OHSS is mild or moderate, with recovery soon after egg retrieval," says Dr. Stephanie Thompson, a reproductive endocrinology and ...
Theca lutein cyst is a type of bilateral functional ovarian cyst filled with clear, straw-colored fluid. These cysts result from exaggerated physiological stimulation (hyperreactio luteinalis) due to elevated levels of beta-human chorionic gonadotropin (beta-hCG) or hypersensitivity to beta-hCG.
Severe cases often require hospitalization, removal of fluid from the abdomen, and replacement of fluid in the blood. OHSS is most prevalent in very high responders, almost always those with more than 20 developing ovarian follicles, who are triggered with hCG. One means of greatly reducing OHSS risk is to trigger with GnRH agonist instead of hCG.
There can be short-term complications, and despite the practice growing in popularity, little is known about the long-term risks to egg donors. ... (OHSS), which can be life-threatening in severe ...
On the other hand, the GnRH antagonist protocol has a lower risk of ovarian hyperstimulation syndrome (OHSS), which is a life-threatening complication. [45] For the ovarian hyperstimulation in itself, injectable gonadotropins (usually FSH analogues) are generally used under close monitoring.
Ovulatory disorders result in infrequent ovulation (Oligoovulation) or absent ovulation (anovulation) which causes infertility. The World Health Organisation (WHO) has classified anovulation into three main classes, which are hypogonadotropic hypogonadal anovulation (Class 1), normogonadotropic normoestrogenic anovulation (Class 2), and hypergonadotropic hypoestrogenic anovulation (Class 3).
The main risk associated with the administration of medications to stimulate the ovaries is ovarian hyperstimulation syndrome (OHSS). This is a transient syndrome in which there is increased permeability of the blood vessels, resulting in fluid loss from the vessels into the surrounding tissues.
