Human follicular fluid levels of calcium, copper and zinc. 1987

Human follicular fluid was collected under laparoscopic vision from 33 follicles in patients stimulated with clomiphene-human menopausal gonadotrophin in an IVF programme. Thirty-one oocytes were obtained from 26 follicles from which clear follicular fluid was obtained, and 16 oocytes fertilized and cleaved. The follicular fluid was analysed for calcium, copper and zinc using atomic absorption spectroscopy. The mean levels of calcium, copper and zinc were 86.9 +/- 11.6, 1.16 +/- 0.29, and 0.72 +/- 0.12 micrograms/ml, respectively. Their levels were not significantly different in the follicular fluid collected from follicles of different sizes, with or without oocyte, and follicles with oocytes that were fertilized and were unable to be fertilized. Therefore, the concentrations of these elements do not seem to reflect oocyte status or maturity.

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
D002118 Calcium A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes. Coagulation Factor IV,Factor IV,Blood Coagulation Factor IV,Calcium-40,Calcium 40,Factor IV, Coagulation
D003300 Copper A heavy metal trace element with the atomic symbol Cu, atomic number 29, and atomic weight 63.55. Copper-63,Copper 63
D005260 Female Females
D005307 Fertilization in Vitro An assisted reproductive technique that includes the direct handling and manipulation of oocytes and sperm to achieve fertilization in vitro.

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.

D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D015032 Zinc A metallic element of atomic number 30 and atomic weight 65.38. It is a necessary trace element in the diet, forming an essential part of many enzymes, and playing an important role in protein synthesis and in cell division. Zinc deficiency is associated with ANEMIA, short stature, HYPOGONADISM, impaired WOUND HEALING, and geophagia. It is known by the symbol Zn.
