Oocytes are immature egg cells that develop to maturity within a follicle in the ovary. Oocyte abnormalities can occur due to several factors, including premature ovarian insufficiency (POI), other maturation abnormalities, maternal ageing, and mitochondrial abnormalities.
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. Follicular Development
An oocyte (/ ˈ oʊ ə s aɪ t /, oöcyte, or ovocyte is a female gametocyte or germ cell involved in reproduction. In other words, it is an immature ovum, or egg cell. An oocyte is produced in a female fetus in the ovary during female gametogenesis. The female germ cells produce a primordial germ cell (PGC), which then undergoes mitosis ...
The postcoital test (PCT), also known as the Sims test, Hühner test ,Sims–Hühner test, or cervical mucous penetration assay is a test in the evaluation of infertility. The test examines interaction between sperm and mucus of the cervix .
An immature ovum is a cell that goes through the process of oogenesis to become an ovum. It can be an oogonium , an oocyte , or an ootid . An oocyte, in turn, can be either primary or secondary, depending on how far it has come in its process of meiosis .
Seminal fluid contains several proteins that interact with epithelial cells of the cervix and uterus, inducing active gestational immune tolerance. There are significantly improved outcomes when patients are exposed to seminal plasma around the time of oocyte retrieval, with statistical significance for clinical pregnancy , but not for ongoing ...
Antral follicles are cells early in the process of developing from an oogonium into a mature oocyte. A physician may use a transvaginal ultrasound to visualize and count the number of antral follicles in each of a woman's ovaries in order to determine her ovarian reserve; however AFC is not predictive of embryo quality.

Supravital stain of a smear of human blood from a patient with hemolytic anemia. The reticulocytes are the cells with the dark blue dots and curved linear structures (reticulum) in the cytoplasm. The normal fraction of reticulocytes in the blood depends on the clinical situation but is usually 0.5% to 2.5% in adults and 2% to 6% in infants.
