The first aim of the research conducted as part of this thesis was to investigate the expression and activities of 11PHSD enzymes in porcine mural granulosa cells and COCs from small, medium and large antral follicles, as well as from ovarian cysts. Both cloned lipHSD enzymes (11 PHSD 1 and 11PHSD2) were expressed in porcine granulosa cells however the results of the expression studies in COCs ...

INTRODUCTION The aim of this retrospective case control study was to identify predictors of ovarian response and pregnancy outcomes in intrauterine insemination (IUI). MATERIAL AND METHODS One hundred women undergoing IUI cycles with clomiphene citrate were enrolled. The number of antral follicles and the total ovarian volume by ultrasound, and the basal levels of follicle-stimulating hormone...

the aim of this study was to investigate the in vitro developmental competence of isolated pre-antral follicles derived from vitrified ovaries in the presence of coenzyme q 10 (coq 10 ) . mice pre-antral follicles derived from fresh and vitrified-warmed ovarian tissues were in vitro cultured individually in α-mem medium supplemented with or without coq 10 , followed by adding human chorionic go...

BACKGROUND There is substantial evidence both in humans and in animals that a prolonged reduction in plasma thyroid hormone concentration leads to reproductive problems, including disturbed folliculogenesis, impaired ovulation and fertilization rates, miscarriage and pregnancy complications. The objective of the present study is to examine the consequences of chronic hypothyroidism, induced in ...

BACKGROUND The objective of our study was to identify the correlations between the tests currently used in ovarian reserve assessment: anti-Mullerian hormone (AMH), follicle stimulating hormone (FSH) and antral follicle count (AFC) and to distinguish the most reliable markers for ovarian reserve in order to select an adequate strategy for the initial stages of infertility treatment. MATERIALS...

Aim: We sought to create and describe a self-made simulator designed created for teaching purposes: high-fidelity ultrasound phantom demonstrating antral follicle count, supervision of controlled ovarian stimulation, ultrasound-guided oocyte retrieval. Materials methods: The uterus ovaries the were made from beef tongue, male condom, latex gloves, cotton suture threads, bi-distilled water, gel....

Our objective has been to compare the IVF and in vitro production (IVP) of embryos from low and high antral follicle count (AFC) heifers. This is the fourth year of the study with years 1 to 3 reported individually. For this report, we add data for the fourth year and present a combined analysis (years 1 to 4) for the first time. Each year, AFC was determined on ~120 Angus heifers using transre...

It is recognised that ovarian factors, including steroid and protein hormones, are critical in the feedback regulation of pituitary gonadotropins; however, their individual contributions are less defined. The aim of this study was to explore the reciprocal relationships between ovarian and pituitary hormones across the normal ovulatory menstrual cycle as women age. FSH, LH, oestradiol, progeste...
