Women with high telomerase activity in luteinised granulosa cells have a higher pregnancy rate during in vitro fertilisation treatment

Regulation of telomerase activity in ovarian granulosa cells.

Follicular development is characterized by intensive proliferation and differentiation of granulosa cells. It was reported that during follicular growth granulosa cells arise from the population of stem cells. One of the main evidences for stem characteristics of the cell is the ability to express telomerase--an enzyme complex responsible for integrity and stability of chromosome ends (telomere...

Need for Consultation and Training during Bed Rest in Women with High Risk Pregnancy Experience: a Qualitative Study

Background:  Pregnancy in a woman's life is a unique experience. But due to high risk pregnancy and the need to rest in bed, the women and her family are faced with different challenges and needs. The inability to manage these needs will result in crisis and understanding the needs of pregnant women during bed rest is essential to provide comprehensive health care for them. So this qualitative ...

Treatment outcome of women with a single ovary undergoing in vitro fertilisation cycles.

INTRODUCTION Women with a single ovary present a unique problem in assisted reproductive techniques. The aim of our study was to compare the ovarian response and pregnancy rates of women with one ovary and those with two ovaries in assisted reproduction. METHODS A total of 18 consecutive women with a single ovary (n is 22 cycles) were identified. The control group included 44 women with two o...

Pregnancy Rate after First Intra Cytoplasmic Sperm Injection-In Vitro Fertilisation Cycle in Patients with Endometriomawith or without Deep Infiltrating Endometriosis

In Vitro Cell Cycle Synchronization of Sheep Granulosa Cells

Purpose: To investigate the effect of different methods of synchronization on sheep granulosa cell cycle. Materials and Methods: Granulosa cells were aspirated from ovarian follicles and plated in a DMEM medium containing 15% FBS. Upon 70-80% confluency, the medium of the primarycultured as well as the passaged-5 cells were replaced with the medium containing either 0.5% FBS for 24, 48 and 72 h...
