The progesterone positive feedback effect in women after ovariectomy
(2013)
Various ovarian substances regulate the secretion of gonadotrophins during the menstrual cycle, but there are still several unclarified issues. The aim of this study was to investigate the positive feedback effect of ...
The role of gonadotropins in the follicular phase
(2010)
Folliculogenesis in humans is a lengthy process that involves several regulators. Pituitary gonadotropins play crucial roles in the late stages, particularly in the last 15 days of follicle maturation. During the intercycle ...
Effect of ghrelin on gonadotrophin secretion in women during the menstrual cycle
(2009)
It has been suggested that ghrelin may affect reproduction in animals by decreasing pituitary LH secretion. The role of ghrelin on LH secretion in women has not been investigated. Our aim was to assess the effect of ghrelin ...
Genes and Conditions Controlling Mammalian Pre- and Post-implantation Embryo Development
(2015)
Embryo quality during the in vitro developmental period is of great clinical importance. Experimental genetic studies during this period have demonstrated the association between specific gene expression profiles and the ...
Prognostic value of follicular fluid 25-OH vitamin D and glucose levels in the IVF outcome
(2010)
Objectives: The aim of the present study was to measure serum and follicular fluid 25-OH vitamin D and glucose levels in women who underwent IVF-ET treatment and to further investigate whether the circulating 25-OH vitamin ...
Sperm DNA fragmentation measured by Halosperm does not impact on embryo quality and ongoing pregnancy rates in IVF/ICSI treatments
(2015)
Sperm DNA fragmentation (SDF) has been proposed to be one of the main markers regarding male infertility. A prospective study was performed to assess primarily whether sperm DNA damage has any impact on embryological data ...
The impact of cigarette smoking and alcohol consumption on sperm parameters and sperm DNA fragmentation (SDF) measured by Halosperm(A (R))
(2014)
Both cigarette smoking and alcohol consumption are somehow implicated in sperm function, but the impact of these two lifestyle factors on sperm parameters remains controversial. The present study is focused on the impact ...
Effect of the Position of the Polar Body During ICSI on Fertilization Rate and Embryo Development
(2010)
This prospective study was designed to evaluate and clarify further whether the position of the polar body (PB) in relation to injection site during intracytoplasmatic sperm injection (ICSI) has an impact on fertilization ...
