The induction of multiple follicular growth during ovarian stimulation for in vitro fertilization (IVF) implies follicular asynchrony. As a consequence oocytes of different quality are obtained. The maturity and fertilizability of oocytes cannot sufficiently be predicted by their morphological appearance under the light microscope. Looking for additional parameters of oocyte quality, FSH, hCG, estradiol (E2), progesterone (P), testosterone (T), prolactin (PRL) and cAMP were analysed in human follicular fluid (FF) containing a morphologically mature oocyte. The evaluation of the relationship between FF values and oocyte fertilization showed the following results: no differences of FSH, hCG, E2, P and T concentrations in FF between the group of fertilized and not fertilized ova. However, significant differences were detected for PRL and cAMP. In FF of fertilized oocytes PRL content was higher (38.8 +/- 2.2 vs 29.7 +/- 2.3 ng/ml, P less than 0.01) and cAMP level was lower (32.7 +/- 1.9 vs 59.8 +/- 7.4 pmol/ml, P less than 0.01) as compared with FF of unfertilizable oocytes. In conclusion PRL- and cAMP concentration of FF might be additional parameters of oocyte maturation and fertilizability.

UI MeSH Term Description Entries
D009865 Oocytes Female germ cells derived from OOGONIA and termed OOCYTES when they enter MEIOSIS. The primary oocytes begin meiosis but are arrested at the diplotene state until OVULATION at PUBERTY to give rise to haploid secondary oocytes or ova (OVUM). Ovocytes,Oocyte,Ovocyte
D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation. Radioimmunoassays

D004702 Endocrine Glands Ductless glands that secrete HORMONES directly into the BLOOD CIRCULATION. These hormones influence the METABOLISM and other functions of cells in the body. Endocrine Gland,Gland, Endocrine

D005306 Fertilization The fusion of a spermatozoon (SPERMATOZOA) with an OVUM thus resulting in the formation of a ZYGOTE.

D006080 Ovarian Follicle An OOCYTE-containing structure in the cortex of the OVARY. The oocyte is enclosed by a layer of GRANULOSA CELLS providing a nourishing microenvironment (FOLLICULAR FLUID). The number and size of follicles vary depending on the age and reproductive state of the female. The growing follicles are divided into five stages: primary, secondary, tertiary, Graafian, and atretic. Follicular growth and steroidogenesis depend on the presence of GONADOTROPINS.

D000328 Adult A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available. Adults
D012739 Gonadal Steroid Hormones Steroid hormones produced by the GONADS. They stimulate reproductive organs, germ cell maturation, and the secondary sex characteristics in the males and the females.
