OBJECTIVE: To investigate the psychologic impact of male factor infertility on men in couples undergoing assisted reproductive treatment in Turkey. STUDY DESIGN: A prospective study was carried out in a total of 105 men: 43 with male factor, 31 with female factor and 31 with unexplained infertility diagnoses. The men answered questionnaires-State Trait Anxiety Inventory, State Trait Anger Expression Inventory and Beck Depression Inventory-during treatment. The scores from each questionnaire were analyzed and compared according to the infertility diagnosis. RESULTS: No significant differences were found in measures of anxiety, anger . . .or depression among men with male factor, female factor and unexplained infertility. CONCLUSION: In the current preliminary study performed on a group of Turkish men who applied for in vitro fertilization treatment, it was found that male factor infertility as the cause of the couple's infertility problem did not have an adverse effect on the psychologic status of men undergoing assisted reproductive treatment. It is suggested that men's psychologic adjustment to their own infertility diagnosis does not indicate that they are psychologically ill. © Journal of Reproductive Medicine®, Inc Daha fazlası Daha az

Vascular endothelial growth factor (VEGF) and its receptors are present in both male and female reproductive systems. In this experimental study, the effect of different concentrations of VEGF on sperm motility and survival in vitro was investigated. Human spermatozoa, collected from voluntary, proven fertile donors, were incubated in sperm washing medium containing different concentrations of VEGF (5, 10, 15, 20 ng/ml) for 24 h in a university reproductive endocrinology laboratory setting. Assessment of VEGF action on sperm motion characteristics was evaluated using a computer-assisted semen analyser. Sperm survival was determined . . .by hypo-osmotic swelling and eosin-Y dye tests. VEGF had a positive effect on some parameters of sperm motility in a concentration-dependent manner. Maximal effect was observed at a concentration of 15 ng/ml; motility, progression, straight-line velocity and curvilinear velocity of VEGF-exposed spermatozoa were significantly increased (P < 0.05) at this concentration. However, sperm viability was not prolonged at any concentration of VEGF as shown by hypo-osmotic swelling and eosin-Y dye tests. VEGF may increase some sperm motility parameters, but not survival, in a concentration-dependent manner in vitro. © 2009 Published by Reproductive Healthcare Ltd Daha fazlası Daha az

The aim of this study was to evaluate the effect of an electromagnetic field (EMF), generated close to the ovaries, on primordial follicles. A total of 16 rats were used in this study. The study group consisted of rats exposed to an EMF in the abdominal region for 15 min/d for 15 days. Both the study and control group were composed of eight rats. After the treatment period of 15 days, the ovaries of the rats were extracted, and sections of ovarian tissue were taken for histological evaluation. The independent samples t test was used to compare the two groups. In the study group, the means of the right and left ovarian follicle numbe . . .rs were 34.00 ± 10.20 and 36.00 ± 10.53, respectively. The average total ovarian follicle number was 70.00 ± 19.03. In the control group, the means of the right and left ovarian follicle numbers were 78.50 ± 25.98 and 71.75 ± 29.66, respectively, and the average total ovarian follicle number was 150.25 ± 49.53. The comparisons of the means of the right and left ovarian follicle numbers and the means of the total ovarian follicle numbers between the study and control groups indicated that the study group had significantly fewer follicles (p < 0.001, p = 0.011, and p = 0.002, respectively). This study found a significant decrease in the number of ovarian follicles in rats exposed to an EMF. Further clinical studies are needed to reveal the effects of EMFs on ovarian reserve and infertility. Copyright © 2015, Kaohsiung Medical University. Published by Elsevier Taiwan LLC.

Stem cells can be used in different areas of obstetrics and gynecology. Adult stem cells are specialized cells found within many tissues of the body where they function in tissue homeostasis and repair. In vitro they have been shown to differentiate into a wide variety of cell types. Hematopoietic stem cells (HSC) have been used to set up therapeutic strategies for the treatment of gynecological solid tumors such as ovarian cancer. Stem cells can be used for prenatal transplantation and in utero gene therapy. Also stem cells can be used in infertility and IVF for research and treatment. © 2008 Elsevier Ltd. All rights reserved.
