The impact of cigarette smoking and alcohol consumption on sperm parameters and sperm DNA fragmentation (SDF) measured by Halosperm(A (R))
Anifandis, G.; Bounartzi, T.; Messini, C. I.; Dafopoulos, K.; Sotiriou, S.; Messinis, I. E. (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 ... -
Inhibin secretion in women with the polycystic ovary syndrome before and after treatment with progesterone
Dafopoulos, K.; Venetis, C.; Messini, C. I.; Pournaras, S.; Anifandis, G.; Garas, A.; Messinis, I. E. (2011)Objectives: It has been suggested that inhibin secretion is altered in women with the polycystic ovary syndrome (PCOS). However, the contribution of a preceding luteal phase has not been taken into account. The aim of the ... -
Inhibitory Effect of Submaximal Doses of Ghrelin on Gonadotropin Secretion in Women
Messini, C. I.; Dafopoulos, K.; Malandri, M.; Georgoulias, P.; Anifandis, G.; Messinis, I. E. (2014)The effect of ghrelin on gonadotropin secretion has been equivocal. Recent data have shown an inhibitory effect of repeated injections of ghrelin on nocturnal LH and FSH secretion in women. The aim of this study was to ... -
Intraperitoneal Dissemination of Endometrial Cancer Cells After Hysteroscopy A Systematic Review and Meta-Analysis
Polyzos, N. P.; Mauri, D.; Tsioras, S.; Messini, C. I.; Valachis, A.; Messinis, I. E. (2010)Introduction: Hysteroscopy is a diagnostic procedure with a high accuracy in diagnosing endometrial cancer. Because of the increase of intrauterine pressure during distention media inflation, several retrospective studies ... -
Luteal-phase endocrinology
Messinis, I. E.; Messini, C. I.; Dafopoulos, K. (2009)The corpus luteum is formed from the pre-ovulatory follicle under the action of the mid-cycle LH surge. LH is the main luteotrophic hormone in women controlling luteal structure and function during the normal menstrual ... -
Metformin reduces the expression of corticotrophin releasing hormone and urocortin in the endometrium of normal women
Dafopoulos, K.; Vrekoussis, T.; Chalvatzas, N.; Messini, C. I.; Kalantaridou, S.; Georgoulias, P.; Messinis, I. E.; Makrigiannakis, A. (2012) -
Metformin reduces the expression of corticotropin-releasing hormone and urocortin in the endometrium of healthy women
Dafopoulos, K.; Vrekoussis, T.; Chalvatzas, N.; Messini, C. I.; Kalantaridou, S. N.; Georgoulias, P.; Messinis, I. E.; Makrigiannakis, A. (2013)Objective: To investigate the effect of metformin administration on the expression of endometrial corticotrophin-releasing hormone (CRH) and urocortin (UCN) in the midluteal phase of the cycle. Design: Experimental study, ... -
Novel aspects of the endocrinology of the menstrual cycle
Messinis, I. E.; Messini, C. I.; Dafopoulos, K. (2014)Ovarian control of gonadotrophin secretion is normally achieved via the feedback mechanisms mediated by oestradiol and progesterone. Evidence has been provided that nonsteroidal substances, such as inhibin A and B, participate ... -
Obesity in PCOS and Infertility
Messinis, I. E.; Messini, C. I.; Dafopoulos, K. (2013) -
Polycystic ovaries and obesity
Messinis, I. E.; Messini, C. I.; Anifandis, G.; Dafopoulos, K. (2015)Almost 50% of the women with polycystic ovary syndrome (PCOS) are obese. Obesity in PCOS affects reproduction via various mechanisms. Hyperandrogenism, increased luteinizing hormone (LH) and insulin resistance play a pivotal ... -

Zavos, A.; Dafopoulos, K.; Georgoulias, P.; Messini, C. I.; Verikouki, C.; Messinis, I. E. (2010) -
The progesterone positive feedback effect in women after ovariectomy
Zavos, A.; Dafopoulos, K.; Messini, C. I.; Georgoulias, P.; Verikouki, C.; Anifandis, G.; Garas, A.; Messinis, I. E. (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 ... -
Prognostic value of follicular fluid 25-OH vitamin D and glucose levels in the IVF outcome
Anifandis, G. M.; Dafopoulos, K.; Messini, C. I.; Chalvatzas, N.; Liakos, N.; Pournaras, S.; Messinis, I. E. (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 ... -
The role of gonadotropins in the follicular phase
Messinis, I. E.; Messini, C. I.; Dafopoulos, K. (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 ... -
Single nucleotide polymorphism rs 175080 in the MLH3 gene and its relation to male infertility

Sperm DNA fragmentation measured by Halosperm does not impact on embryo quality and ongoing pregnancy rates in IVF/ICSI treatments
Anifandis, G.; Bounartzi, T.; Messini, C. I.; Dafopoulos, K.; Markandona, R.; Sotiriou, S.; Tzavella, A.; Messinis, I. E. (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 ... -
