3-dimensional [18 F]FDG-PET image with 3D ROI generated by a threshold based algorithm.The blue dot in the MIP image bottom right marks the maximum SUV within the ROI.. The standardized uptake value (SUV) is a nuclear medicine term, used in positron emission tomography (PET) as well as in modern calibrated single photon emission tomography (SPECT) imaging for a semiquantitative analysis.

An ovarian pregnancy can be mistaken for a tubal pregnancy or a hemorrhagic ovarian cyst or corpus luteum prior to surgery. [8] Sometimes, only the presence of trophoblastic tissue during the histologic examination of material of a bleeding ovarian cyst shows that an ovarian pregnancy was the cause of the bleeding.
In 2015 a research was done on the role of autoimmunity in premature ovarian failure. [11] In 2014 there was an ovarian autoimmune disease research that revealed at least two mechanisms that protect the ovary from an autoimmune attack. [12] Research showed that Theca cells were targeting the autoimmune deficiency within the ovary.
Four criteria for differentiating ovarian from other ectopic pregnancies: The gestational sac is located in the region of the ovary. The ectopic pregnancy is attached to the uterus by the ovarian ligament. Ovarian tissue in the wall of the gestational sac is proved histologically. The tube on the involved side is intact.
In vitro fertilisation (IVF) is a process of fertilisation in which an egg is combined with sperm in vitro ("in glass"). The process involves monitoring and stimulating a woman's ovulatory process, then removing an ovum or ova (egg or eggs) from her ovaries and enabling a man's sperm to fertilise them in a culture medium in a laboratory.
Montevideo units are a method of measuring uterine performance during labor.They were created in 1949 by two physicians, Roberto Caldeyro-Barcia and Hermogenes Alvarez, from Montevideo, Uruguay.
The decline in ovarian reserve appears to occur at a constantly increasing rate with age, [17] and leads to nearly complete exhaustion of the reserve by about age 52. As ovarian reserve and fertility decline with age, there is also a parallel increase in pregnancy failure and meiotic errors resulting in chromosomally abnormal conceptions.
In vitro maturation (IVM) is the technique of letting the contents of ovarian follicles and the oocytes inside mature in vitro.It can be offered to women with infertility problems, combined with In Vitro Fertilization (IVF), offering women pregnancy without ovarian stimulation.
