Oxidative stress markers in preovulatory follicular fluid in humans.

Relationship between Energy Expenditure Related Factors and Oxidative Stress in Follicular Fluid

Oxygen and steroid concentrations in preovulatory follicles of lactating dairy cows exposed to acute heat stress.

Maternal heat stress reduces oocyte competence for fertilization and post-fertilization development, but the mechanism is unknown. The present experiment investigated two potential mechanisms: (1) reduced oxygen delivery to the preovulatory follicle (due to increased thermoregulatory vascular perfusion of skin and respiratory tract); (2) reduced follicular steroid synthesis. These hypotheses we...

O-30: Impact of Environment Tobacco Smoke Exposure on Oxidative Stress in Antral Follicle and Assisted Reproduction Outcomes

Background: Cigarette smoke contains many oxidants and may alter the human reproduction by inducing oxidative stress (OS) in both active and passive smokers. This study was designed to evaluation the effect of environment tobacco smoke (ETS) exposure on oxidative stress in follicular follicle and assisted reproduction outcomes. Materials and Methods: A prospective study was carried out on 236 i...

Evaluation of the relationship between follicular fluid oxidative stress, ovarian hormones, and response to gonadotropin stimulation.

OBJECTIVE To investigate the relationship between oxidative stress and the underlying causes of infertility, preovulatory ovarian hormones, and ovarian response to gonadotropin stimulation in patients undergoing assisted reproductive techniques. DESIGN Prospective, cross-sectional study. SETTING Assisted conception unit, university hospital. PATIENT(S) One hundred thirty women presenting ...

Does dietary fat intake influence oocyte competence and embryo quality by inducing oxidative stress in follicular fluid?

BACKGROUND Fat-rich diet may alter oocyte development and maturation and embryonic development by inducing oxidative stress (OS) in follicular environment. OBJECTIVE To investigate the relationship between fat intake and oxidative stress with oocyte competence and embryo quality. MATERIALS AND METHODS In observational study follicular fluid was collected from 236 women undergoing assisted r...
