Polycystic ovaries were defined with ultrasound imaging in a series of 173 women who presented to a gynaecological endocrine clinic with anovulation or hirsutism. Polycystic ovaries were found in 26% of women with amenorrhoea, 87% with oligomenorrhoea, and 92% with idiopathic hirsutism--that is, hirsutism but with regular menstrual cycles. Fewer than half the anovulatory patients with polycysti...

Unlike adult Drosophila ovaries, pupal ovaries are relatively difficult to access and examine due to their small size, translucence, and encasing within a pupal case. The challenge of dissecting pupal ovaries also lies in their physical location within the pupa: the ovaries are surrounded by fat body cells inside the pupal abdomen, and these fat cells must be removed to allow for proper antibod...

BACKGROUND The objective of this study was to perform complex characterization of cryopreserved and then autotransplanted ovaries including determination of the ability to respond to in vivo follicle stimulating hormone (FSH)-treatment, fertilizability of retrieved oocytes, and morphology, vascularization, cellular proliferation and apoptosis in sheep. METHODS Mature crossbred ewes were divid...

The present study aims to investigate if Cimicifuga racemosa (L.) Nutt extract (CIMI) reduces deleterious effects of dexamethasone (DEXA) in ovaries cultured vitro. Mouse were collected and DMEM+ only or supplemented with 5 ng/mL CIMI, 4 DEXA, both CIMI DEXA. at 37.5°C 5% CO2 for 6 days. Ovarian morphology, follicular ultrastructure, the levels mRNA Bax, Bcl-2, Caspase-3 evaluated. results show...

background: retinoids have been suggested to play a role in oogenesis and oocyte survival. objective: in the present study the effects of retinol palmitate were investigated on differential follicular counts in response to superovulation as well as follicle quality after vitrification of ovaries. materials and methods: ten, 4 week old female balb/c mice were randomly assigned to either paraffin...

Objective: To assess the response to superovulation for in vitro fertilization (IVF) in patients with unilateral endometriomas with diameter ≥ 5 cm and in the contralateral healthy ovary. Study design: This retrospective analysis of a prospectively collected database included patients who underwent superovulation for IVF/ICSI cycles and had unoperated single unilateral endometrioma with diamete...

We investigated aromatization and the mechanism of action of epidermal growth factor (EGF) and transforming growth factor alpha (TGFalpha) on oestradiol biosynthesis in freshly prepared granulosa cells from polycystic ovaries. Freshly prepared granulosa cells from polycystic ovaries incubated for only 3 h under basal conditions secreted significantly (P< 0.001) greater amounts of oestradiol-17b...

Lily tepals have a short lifespan. Once the tepals senesce, the ornamental value of the flower is lost. Some cultivars have attractive purple ovaries and fruits which greatly enhance the ornamental value of Asiatic hybrid lilies. However, little is known about the molecular mechanisms of anthocyanin biosynthesis in Asiatic hybrid lily ovaries. To investigate the transcriptional network that gov...
