Follicle and oocyte growth is under the control of systemic gonadotropins and various local intraovarian factors. The present study was undertaken to examine the efficacy of peptide(s) isolated from ovine follicular fluid on preantral and antral follicles, oocytes, cumulus and granulosa cells, and oviductal epithelial cell growth in vitro in a heterologous species (Bubalus bubalis). Follicular ...
Pregnancy success results from the interaction of multiple factors, among them are folliculogenesis and early embryonic development. Failure during these different processes can lead to difficulties in conception. Alternatives to overcome these problems are based on assisted reproductive techniques. Extracellular vesicles are cell-secreted vesicles present in different body fluids and contain b...
BACKGROUND Fatty acids are known to be critically important in multiple biological functions. Phospholipid fatty acids of follicular fluid, an important microenvironment for the development of oocytes, may contribute to the women's fertility and the efficacy of assisted reproduction techniques. The aim of this study was to investigate the effect of fatty acid composition of follicular fluid pho...
background: some evidences showed that the secretion of uterine tube vagina and follicular fluid (ff) affects x and y-chromosome populations. sperm selection with x or y chromosome can added to oocyte for gender desired. the isolation of x y sperm have done and all efforts in this field are done to make culture media similar to in vivo condition. the objective of this study was to find if the f...
The genetic and molecular mechanisms that control the development of capillary blood vessels during follicular development are beginning to be elucidated. Ovarian follicles contain and produce angiogenic factors that may act alone or in concert to regulate thecal angiogenesis. These factors are ultimately controlled by endocrine, paracrine and autocrine regulation in the ovary. Our recent study...
The biochemical components and factors like protein and enzyme components of follicular fluid like lipase, amylase and creatinine phosphokinase concentration show an increasing trend as the follicles mature, while some other components like Alpha-fetoprotein, Acid Phosphatase and Alkaline Phosphatase concentration decreases with increase in follicular size. Moreover, presence of amylase, lipase...
The main objective of the study was to asses whether the environmental cadmium exposure in the Czech Republic is high enough to be able to affect significantly the human reproduction. Cadmium levels were measured in the blood and follicular fluid of 220 women in in vitro fertilization (IVF) therapy, using atomic absorption spectrometry. The mean value of cadmium in venous blood was 0.85 ng x ml...
The frequency of endocrine abnormalities during the follicular phase in non-pregnant women with a history of recurrent abortion was investigated in a case-control study. A total of 42 consecutive women with recurrent spontaneous abortion (three or more consecutive abortions, mean +/- SD: 3.9 +/- 1.1 range 3-8) with no parental chromosome rearrangement or uterine abnormality were studied during ...
