RESUMO
As a part of male assessment, conventional sperm parameters including morphologic features have been dedicated as major factors influencing fertilisation and pregnancy rates in assisted reproductive technology (ART). Genomic integrity of spermatozoa has also been found to influence fertility prognosis, and hence, sperm DNA fragmentation index (DFI) has been adopted by many centres to document this entity. Despite several suggested approaches, there is lack of universal consensus on optimising fertility outcomes in males with high sperm DFI. In this context, the results from cycles using testicular spermatozoa (TESA) obtained by aspiration were compared with those of ejaculated spermatozoa (EJ) in normozoospermic subjects with high sperm DFI and previous ART failures. Clinical (41.9% versus 20%) and ongoing pregnancy rates (38.7% versus 15%) were significantly better and miscarriages were lower in TESA group when compared to EJ group. Sperm DFI should be a part of male partner's evaluation following unsuccessful ART attempts. When high DFI is detected (>30%), ICSI using testicular spermatozoa obtained by TESA seems an effective option particularly for those with repeated ART failures in terms of clinical, ongoing pregnancies and miscarriages even though conventional sperm parameters are within normal range.

Fertilisation with intracytoplasmic sperm injection (ICSI) is a consequence of complex molecular interactions between spermatozoon and oocyte. Disruption of the process obviously prompts a frustrating event called total fertilisation failure (TFF). Up to 3% of ICSI cycles may result in TFF, and brief counselling for subsequent cycle management is indispensable. Within this perspective, ICSI cycles of a centre over a 10-year period were analysed to document TFF cases. Initial TFF after ICSI and subsequent ICSI cycle of the same cases were documented to clarify predictive factors of successful outcomes after initial TFF. In subsequent cycles, assisted oocyte activation (AOA) with calcium ionophore and Hypo-osmotic swelling test (HOST)/pentoxifilline for sperm selection was used. In the current analysis, successful fertilisation was achieved in 85% of the cases with previous TFF. The significant contributing factors for successful fertilisation in the latter cycle were: improved oocyte quantity and better sperm morphology. In conclusion, sporadic TFF event in the first and only cycle is usually a technically modifiable condition, but repeated TFF could indicate possible gamete defects, which might not be overcomed in the next modified ICSI cycle.

Melatonin is a neurohormone secreted mainly by the pineal gland that controls circadian rhythm, which is primarily regulated by light. Although melatonin levels are known to be altered in individuals with sleep disorders, melatonin also has modulatory effects on other body systems, including the skeletal and immune systems. In addition, melatonin has been shown to interfere with carbohydrate and lipid metabolism and to have significant antioxidant effects, both directly and via its metabolites. Melatonin levels vary throughout human life and are known to decrease with age but the effects of declining melatonin levels are poorly understood. In women, this age-related decrease in melatonin levels coincides with the menopause. This review aims to summarize the impact of altered melatonin levels in aging women and the outcomes of exogenous replacement therapies.

The purpose of this study was to investigate whether levels of fetal hypoxia markers, S100 and ischaemia modified albumin (IMA) change in cases of intrauterine growth restriction (IUGR). This case-control study included 15 intrauterine growth restricted fetuses and 20 age-matched controls. During delivery of the fetuses, cord blood and maternal blood S100 and IMA levels were studied. The fetal weight and umbilical cord pH values of IUGR fetuses were significantly lower than the control group. The mean maternal and umbilical cord blood values of S100 and IMA were similar in the two groups. IMA levels in cord blood of the IUGR group were significantly higher than maternal levels, whereas umbilical and maternal levels of IMA did not differ among control cases. In cases without brain sparing effect in Doppler ultrasonography, umbilical cord S100 and IMA levels do not change significantly in IUGR when compared with appropriate-for-gestational-age (AGA) fetuses.

This study was designed to evaluate the effect of luteal-phase administration of single-dose gonadotrophin-releasing hormone (GnRH) agonist on pregnancy, implantation and live birth rates in patients who received GnRH antagonist for pituitary suppression. The study population consisted of 164 patients who underwent intracytoplasmic sperm injection (ICSI) after ovulation induction by gonadotrophins and GnRH antagonist for the prevention of a premature LH surge. For luteal-phase support, all the cases received intravaginal 600 mg micronized progesterone. In this prospective study, patients were randomly assigned to two groups. In one group, patients received an additional single dose of GnRH agonist (0.5 mg leuprolide acetate) subcutaneously on day 6 after ICSI, whereas the patients in the other group did not. Although the number of embryos transferred and the grade of the embryos were similar in the two groups, the patients in the luteal-phase agonist group had significantly higher rates of implantation and clinical pregnancy rates ( P < 0.05). When the two groups were compared, there were also statistically significant differences in multiple pregnancy and live birth rates ( P < 0.05). Administration of single-dose GnRH agonist as a luteal-phase support in ovarian stimulation-GnRH antagonist cycles in addition to standard luteal support seems to be effective in all cycle outcome parameters.

Hypogonadotrophic hypogonadism is characterized by oligospermia or azoospermia and low testosterone, FSH and LH concentrations. In such cases, treatment with gonadotrophins is required to produce or increase spermatozoa in the ejaculate but few achieve normal spermatogenesis. After long periods of medical treatment, if the patients still have a low sperm count or azoospermia, assisted reproductive technologies in addition to hormone administration can be offered. Four cases of hypogonadotrophic hypogonadism with persistent azoospermia after at least 10 months of medical treatment are reported. In all four cases, spermatozoa retrieved by testicular sperm extraction and intracytoplasmic sperm injection (ICSI) were used to achieve fertilization. Excess spermatozoa were frozen in all cases. Six ICSI cycles using fresh testicular spermatozoa in four and thawed testicular spermatozoa in two were performed. Although there was no pregnancy in cycles where thawed spermatozoa were used, three clinical pregnancies were achieved in four cycles using fresh testicular spermatozoa. One of them ended with spontaneous abortion at 10 weeks of gestation and the two others resulted in the delivery of three normal offspring. If azoospermia persists after medical treatment, spermatozoa can be obtained surgically from testes and can be used successfully to achieve pregnancy in cases of hypogonadotrophic hypogonadism.

PURPOSE: To determine the effects of levonorgestrel-releasing intrauterine system (LNG-IUS) on ovarian functions, uterine and fibroid volume. METHODS: In this prospective study, LNG-IUS was inserted to 46 women with menorrhagia. The patients were evaluated for serum levels of hemoglobin, FSH, LH and estradiol, ovarian volume, uterine and fibroid volume and Kupperman index scores at the time of insertion, at 6th and 12th months. RESULTS: Serum FSH levels increased in 69% of the device users, the increase of serum FSH levels were statistically significant (P = 0.021). Regression analysis showed significant association between FSH levels and age of the patient (P = 0.001). There were no statistically significant differences in ovarian and uterine volumes. A statistically significant decrease in myoma volumes were observed (P = 0.04). CONCLUSION: The application of LNG-IUS in reproductive age women seems to decrease fibroid size and increase hemoglobin levels without any significant dysfunction on ovaries.

Methylphenidate hydrochloride (MPH), more commonly known as Ritalin, is a piperidine derivative and is the drug most often used to treat attention deficit/hyperactivity disorder, one of the most common behavioural disorders of children and young adults. The aim of this study was to investigate dose-dependent immunohistochemical Dopamine 2 receptor (D2) expression and apoptosis in the rat cornea and cornea. In this study, 27 female pre-pubertal Wistar albino rats, divided into three different dose groups (5, 10 and 20 mg/kg) and their control groups, were used. They were treated orally with methylphenidate dissolved in saline solution for 5 days per week during 3 months. At the end of the third month, after perfusion fixation, eye tissue was removed. Paraffin sections were collected for immunohistochemical and terminal deoxynucleotidyl-transferase-mediated dUTP-biotin nick end labelling assay studies. In our study, we observed that the cornea D2 receptor reactivity showed a dose-related increase after MPH treatment, especially in basal cells of the epithelium and a dose-dependent decrease in the retinal ganglion cell which was statistically meaningful. Analysis of the cornea thickness results showed no meaningful difference between groups. Apoptotic cell number showed a meaningful increase in the high dose treated group compared to the other groups of the study. The data suggest that Ritalin has degenerative effect on the important functional part of the eye, such as cornea and retina and its activating dopaminergic mechanism via similar neuronal paths, functionally and structurally, to induce morphological changes. As a result, we believe that this morphological changes negatively effecting functional organization of the affected cornea and retina.

The aim of this study was to investigate the concentrations of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), leptin, tumor necrosis factor-alpha, interleukin (IL)-1beta and IL-6, in cycles with a premature rise of serum progesterone. 25 intracytoplasmic sperm injection (ICSI) cycles with (Group 1) and 25 ICSI cycles without a premature progesterone elevation (Group 2) were included. The cut-off value of serum progesterone on the day of human chorionic gonadotropin (hCG) administration was 0.9 ng/ml. The indication for ICSI was male factor infertility exclusively. On the day of hCG injection, serum IL-6, VEGF and bFGF were significantly higher in Group 1 (7.7+/-24.5 pg/ml, 290.2+/-161.4 pg/ml and 15.7+/-8.2 ng/ml respectively) than in Group 2 (1.7+/-0.7 pg/ml, 175.2+/-92.1 pg/ml, and 9+/-1.6 ng/ml respectively). On the day of follicular puncture, serum cytokine concentrations were similar in the two groups. IL-6 intrafollicular concentrations were higher in Group 1 (14.7+/-20.7 pg/ml) than in Group 2 (9+/-9.3 pg/ml, p=0.031). There were no differences regarding the ICSI outcome. Patients with serum progesterone above 0.9 ng/ml, have elevated serum concentrations of IL-6, VEGF, and bFGF, as well as elevated intrafollicular concentrations of IL-6. The outcome of ICSI cycles is not associated with premature elevation of progesterone when the cut-off value is set at 0.9 ng/ml.

OBJECTIVE: To define the effect of tranexamic acid use on perioperative and postoperative bleeding and blood transfusion requirements in women undergoing myomectomy. STUDY DESIGN: Among the patients that underwent myomectomy a total of 100 cases were included in the study. The patients (n=50) randomized to receive tranexamic acid were defined as Group I and those receiving saline were defined as Group II. Perioperative blood loss was calculated by measuring the volume in the suction apparatus and weighing the swabs. Postoperative blood loss was defined as the blood volume found in the subfascial suction drain. The two groups were compared for age, body mass index, basal hemoglobin and hematocrit, basal parameters of coagulation, the number and the volume of myomas removed, peri- and postoperative and total blood loss, duration of surgery and blood transfusion requirements. RESULTS: No significant difference was found between the two groups when compared age, body mass index, preoperative blood analysis, the number and volume of myomas removed. Statistically significant differences were found between the two groups when compared for postoperative and total blood loss and duration of surgery (p<0.01, p=0.03 and p=0.03, respectively). Perioperative blood loss and blood transfusion requirements were similar between the two groups (p=0.12 and p=0.25, respectively). There were no complications in either group. CONCLUSION: Our study is the first in the literature evaluating the effectiveness of tranexamic acid use on peri- and postoperative bleeding in gynecological surgery. No additional benefit of intravenous infusion of tranexamic acid was found. Tranexamic acid does not seem to be a useful adjunct in myomectomy if given according to the described protocol in this study.

We investigated the day-night differences in intestinal oxidative-injury and the inflammatory response following total body (TB) or abdominopelvic (AP) irradiation, and the influence of melatonin administration on tissue injury induced by radiation. Rats (male Wistar, weighing 220-280 g) in the irradiated groups were exposed to a dose of 8 Gy to the TB or AP region in the morning (resting period - 1 h after light onset) or evening (activity span - 13 h after light onset). Vehicle or melatonin was administered immediately before, immediately after and 24 h after irradiation (10, 2.0 and 10 mg/kg, ip, respectively) to the irradiated rats. AP (P < 0.05) and TB (P < 0.05) irradiation applied in the morning caused a significant increase in thiobarbituric acid reactive substance (TBARS) levels. Melatonin treatment in the morning (P < 0.05) or evening (P < 0.05) decreased TBARS levels after TB irradiation. After AP irradiation, melatonin treatment only in the morning caused a significant decrease in TBARS levels (P < 0.05). Although we have confirmed the development of inflammation after radiotherapy by histological findings, neither AP nor TB irradiation caused any marked changes in myeloperoxidase activity in the morning or evening. Our results indicate that oxidative damage is more prominent in rats receiving TB and AP irradiation in the morning and melatonin appears to have beneficial effects on oxidative damage irrespective of the time of administration. Increased neutrophil accumulation indicates that melatonin administration exerts a protective effect on AP irradiation-induced tissue oxidative injury, especially in the morning.

The DNA damage in human spermatozoa is a relevant predictor of prognosis in male infertility, whereby increased sperm DNA damage impairs the outcomes of artificial reproduction. Theoretically, DNA damage should alter the special cellular functions of human spermatozoa, and lead to diminished acrosome reaction with reduced fertilization rates. Nevertheless, intracytoplasmic sperm injection (ICSI) has been reported to alleviate such negative outcomes due to DNA damage. This study investigated the relationship between DNA fragmentation and acrosome reaction as well as viability in ICSI patients. The study enrolled 42 men undergoing ICSI due to poor sperm parameters. The DNA fragmentation indexes (DFI) were 4-10% in 38% of the cases, and > or = 10% in 19% of the cases. The results of both acrosome reaction and viability assays showed negative correlations with DFI values in all cases and especially in cases with fertilization rates <60% (P < 0.05). However, such correlations were not found in cases with fertilization rates >60%. There were no live deliveries in patients with high DFI levels (>10%). In conclusion, negative correlations were identified between increased DNA damage, and acrosome reaction and/or viability of human spermatozoa, especially in cases with reduced fertilization rates.

The intrafollicular levels of IGF-I and epidermal growth factor (EGF) were studied in women undergoing controlled ovarian hyperstimulation using the multidose GnRH-antagonist protocol or the long agonist protocol, in an attempt to elucidate whether GnRH-antagonists affect the levels of the two growth factors. The follicular fluid concentration of IGF-I, EGF, estradiol and progesterone were detected in 68 women undergoing ovarian hyperstimulation for intracytoplasmic sperm injection (ICSI) cycles. There were no differences in intrafollicular concentrations of EGF and IGF-I in the two studied groups. Additionally, we found no correlation between the intrafollicular levels of IGF-I or EGF and the ICSI outcome. The intrafollicular levels of IGF-I were positively correlated with those of progesterone. In conclusion, the intrafollicular levels of IGF-I and EGF do not seem to be influenced by the stimulation protocol. The intrafollicular levels of both growth factors can not serve as prognostic markers for the ICSI outcome.

The objectives of this study were to examine the effect of TDZ and BAP on shoot proliferation and to develop a satisfactory rooting procedure for in vitro propagation of caper (Capparis spinosa L). TDZ was found to be more effective than BAP in shoot production. The highest shoot number per explant (45.7) was achieved on the media that contained 4.54 microM TDZ in the absence of IAA. TDZ at 4.54 microM alone or in combination with 0.57 microM IAA did not inhibit shoot elongation, although they produced the most shoots. Dipping the caper shoots in the solution of IBA at 24.6 microM for 10 minutes before planting on MS media, improved the rooting percentage up to 80.5% under a 16 hr photoperiod.

OBJECTIVE: To evaluate and compare the analgesic efficacy and adverse effects of tramadol and pethidine in labor. METHOD: Fifty-nine full term parturients were randomly assigned to one of two groups in active labor. Group 1 received 100 mg pethidine; group 2, 100 mg tramadol, intramuscularly. Analgesic efficacy, maternal side effects, changes in the blood pressure, heart rate, and duration of labor were assessed. RESULT: At 30 and 60 min after drug administration, pain relief was greater in the pethidine group than in tramadol group. The incidence of nausea and fatigue was higher in the tramadol group. Following drug administration the decrease in systolic and diastolic blood pressure and the increase in heart rate were statistically significant in both groups. No significant difference was found between the groups when compared for duration of labor and Apgar scores. None of the neonates developed respiratory depression. CONCLUSION: Pethidine seems to be a better alternative than tramadol in obstetric analgesia because of its superiority in analgesic efficacy and low incidence of maternal side effects.
