Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is observing the relation between serum Vitamin D levels and morphokinesis of time lapse monitored Day 5 embryo in between 18 and 38 years age women undergoing controlled ovarian hyperstimulation (COH) because of unexplained or tubal factor infertility. Individuals will be divided into 2 groups according to serum vitamin D levels as normal or low , and the influence of those levels in morphokinetic parameters of embryos will be identified.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Up to date there are few studies questioning the serum Vitamin D deficiency as a negative factor for pregnancy rates in women undergoing COH cycles and also are displaying different and inconclusive results. This dedicated negative affects may be mediated through endometrial and/or ovarial factors. In experimental animal models Vitamin D receptors have been found in endometrium and ovaries and deficient levels might have been a cause of impaired folliculogenesis. In one of human study Vitamin D has been suggested as a positive regulator of anti- Mullerian hormone (AMH) production. Therefore, we aimed to clarify the affects of Vitamin D on folliculogenesis, oogenesis and embryo quality in COH cycles by using time lapse monitoring.
