Abstract
Telomere length and sperm DNA fragmentation were determined in sperm samples from 27 patients, using a quantitative PCR (Q-PCR) assay and the Sperm Chromatin Dispersion (SCD) test, respectively. Comparisons of the samples before and after swim-up processing demonstrated that this procedure selects a sperm population with longer average telomere size and lower frequency of sperm cells with fragmented DNA.

Abstract
Testicular biopsy is needed to confirm diagnosis in azoospermic patients and to recover spermatozoa, if possible. This report aims to quantitatively analyse the germline markers stage-specific embryonic antigen (SSEA-1), c-KIT and VASA in testicular biopsies with distinct azoospermic aetiologies. Twenty-three testicular biopsies were analysed by flow cytometry and RT-qPCR for c-KIT, SSEA-1 and VASA. In all the Sertoli cell-only (SCO) samples, significantly lower VASA mRNA expression and fewer VASA+ cells were found compared with obstructive controls. Maturation arrest (MA) cases showed significant differences only with the non-mosaic SCO samples when compared for VASA mRNA expression and percentage of VASA+ cells, but not with the mosaics. However, the normalized VASA-KIT parameter obtained by subtracting the percentage of c-KIT+ cells from the percentage of VASA+ cells showed significant differences between the MA and all the SCO samples. RT-qPCR consistently found differences for the VASA expression between SCO mosaic and non-mosaic samples. However, by flow cytometry, only VASA-KIT showed significant differences between them. Conversely, the percentage of SSEA-1+ cells revealed no inter-group differences. In conclusion, testicular biopsies display different expression profiles for c-KIT and VASA depending on the azoospermic aetiology. These results can be used as a complementary tool to create new molecular categories for diagnoses in azoospermic patients, particularly useful to discriminate between mosaic and non-mosaic SCO patients.

Abstract
BACKGROUND The aim of the present study was to evaluate the implication of male factor, in terms of sperm DNA oxidation and fragmentation, and Y chromosome microdeletions in recurrent spontaneous abortion (RSA) of unknown origin in a strictly selected cohort. METHODS A prospective cohort study was carried out in a private university-affiliated setting. Three groups, each comprised of 30 males, were compared. The first was formed by healthy and fertile sperm donors (SD) with normal sperm parameters (control group), the second by men presenting severe oligozoospermia (SO) without RSA history, and the third by men from couples who had experienced idiopathic RSA. Frequency of Y chromosome microdeletions and mean sperm DNA fragmentation and oxidation were determined. RESULTS Y chromosome microdeletions were not detected in any of the males enrolled in the study. Moreover, sperm DNA oxidation measurements were not demonstrated to be relevant to RSA. Interestingly, sperm DNA fragmentation was higher in the SO group than in the RSA and the SD groups, and also higher in the RSA group compared with the SD group, but lacked an adequate predictive power to be employed as a discriminative test of RSA condition. CONCLUSIONS Sperm DNA features and Y chromosome microdeletions do not seem to be related to RSA of unknown origin. Other molecular features of sperm should be studied to determine their possible influence on RSA. Clinicaltrials.gov reference: NCT00447395.

Abstract
OBJECTIVE To differentiate transcripts' expression in the sperm from patients who achieved pregnancy in their first IUI cycle from those who did not. Basic sperm analysis is limited to forecasting pregnancies by means of assisted reproduction. New assays, such as microarray analysis, are potential predictive tools for this purpose. DESIGN Nested case-control study. SETTING University-affiliated private setting. PATIENT(S) Twenty sperm samples were obtained from infertile males undergoing their first IUI cycle with healthy partners. Sperm samples with which pregnancy was achieved (P; n=10) and those with which it was not achieved (NP; n=10) were identified and their respective messenger RNA expression profiles were compared. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Using microarrays, global genome expression was compared in pooled samples from each group. Results were evaluated to detect differentially expressed transcripts (TDEs; FC>2; P<0.05) and to identify those transcripts that were expressed in only one of the groups (exclusive transcripts [ETs]). RESULT(S) In group P, 756 TDEs presented increased expression, whereas 194 in group NP were found to be overexpressed. Furthermore, we found 741 ETs that were expressed only in group P and 976 that were expressed only in group NP. CONCLUSION(S) Results reveal profound differences between expression profiles of sperm samples that impregnate successfully and those that do not. These differences might improve the predictive power of sperm evaluation to estimate IUI success by complementing the basic sperm analysis.

Abstract
Deoxyribonucleic acid fragmentation and oxidative DNA damage were simultaneously determined in the same sperm cell, incubating with an 8-oxoguanine DNA probe on human spermatozoa processed by the sperm chromatin dispersion test. The assay was validated by incubation with agents that induce DNA fragmentation with or without oxidative base damage. In all samples examined, increased levels of 8-oxoguanine were present only in those spermatozoa with fragmented DNA, suggesting a link between both DNA damage types.

Abstract
The equilibrium of the creation and scavenging of free radicals is mandatory in the spermatozoa to fertilize and initiate a full-term pregnancy. The glutathione (GSH) enzymatic system studies have discovered its relationship with oxidative stress in the ejaculate and new strategies to regulate its activity in the semen could be developed. Intracellular sperm GSH system components are altered in infertile men, and these alterations seem to be linked to sperm morphology. We have been able to correlate embryo morphology on 8 cell embryos with the sperm expression of GPx family members; this relationship appears quite promising for discovery of molecular causes of male infertility. Oxidative stress imbalance potentially leads to damage of the structure of plasma membrane. The freezing and subsequent thawing of sperm is a physically stressful process carried out during routine procedures in assisted reproduction, which results in a highly variable and unpredictable reduction of motile sperm. Subsequently, oxidative status can positively or negatively affect the motility, viability, and fertilizing capacity of thawed sperm. A reserve of glutathione, together with GPx expression, is necessary to eliminate free radicals using GSH or GPx-4 like structural protein and seems to be essential for a good post thaw recovery.

Abstract
Human immunodeficiency virus and hepatitis C infections are sexually transmitted diseases that require sperm samples to be pretreated to eliminate the viral presence before their safe use in assisted reproduction treatments. In this report we describe our experience with sperm washing protocols applied to sperm cells from testicular biopsies as well as the results obtained in subsequent assisted reproduction treatments on seropositive males that are also azoospermic.

Abstract
Kisspeptins, the products of the KiSS-1 gene acting via G protein-coupled receptor 54 (GPR54), have recently emerged as pivotal signals in the hypothalamic network triggering the preovulatory surge of gonadotropins and, hence, ovulation. Additional actions of kisspeptins at other levels of the hypothalamic-pituitary-ovarian axis have been suggested but remain to date scarcely studied. We report herein the pattern of expression of KiSS-1 and GPR54 in the human and nonhuman primate ovary and evaluate changes in ovarian KiSS-1 expression in a rat model of ovulatory dysfunction. KiSS-1 and GPR54 mRNAs were detected in human ovarian tissue and cultured granulosa-lutein cells. In good agreement, kisspeptin immunoreactivity was observed in cyclic human and marmoset ovaries, with prominent signals in the theca layer of growing follicles, corpora lutea, interstitial gland, and ovarian surface epithelium. GPR54 immunoreactivity was also found in human theca and luteal cells. Administration of indomethacin to cyclic female rats disturbed ovulation and resulted in a dramatic drop in ovarian KiSS-1, but not GPR54, cyclooxygenase-2 (COX-2), or progesterone receptor, mRNA levels at the time of ovulation; an effect mimicked by the selective COX-2 inhibitor NS398 and rescued by coadministration of PGE(2). Likewise, the stimulatory effect of human choriogonadotropin on ovarian KiSS-1 expression was partially blunted by indomethacin. In contrast, KiSS-1 mRNA levels remained unaltered in another model of ovulatory failure, i.e., the RU486-treated rat. In summary, we document for the first time the expression of KiSS-1/kisspeptin and GPR54 in the human and nonhuman primate ovary. In addition, we provide evidence for the ability of inhibitors of COX-2, known to disturb follicular rupture and ovulation, to selectively alter the expression of KiSS-1 gene in rat ovary. Altogether, our results are suggestive of a conserved role of local KiSS-1 in the direct control of ovarian functions in mammals.

Abstract
OBJECTIVE One byproduct resulting from free radical damage is the DNA hydroxylation also known as DNA oxidation. Our aim with this work was to determine the relevance of sperm DNA oxidation on embryo quality in oocyte donation cycles. DESIGN We prospectively studied pairs of oocyte donation cycles, i.e., the same oocyte donors, donating to two recipients, where the only difference between the two treatments was the use of a different sperm sample. SETTING University-affiliated private IVF setting. PATIENT(S) Infertile male partners from couples undergoing oocyte donation cycles (n = 38): 76 semen aliquots analyzed before and after semen processing by swim up. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) We measured sperm DNA oxidation by flow cytometry using the OxiDNA assay and correlated it with embryo quality parameters, implantation, and pregnancy outcome. RESULT(S) A positive correlation was seen between embryo fragmentation and DNA oxidation of capacitated samples at 48 hours and 72 hours after fertilization. However, when we analyzed the differences in the IVF outcome parameters of the couples who shared the oocyte cohort (same donor) with the differences in the OxiDNA values, we observed increased and further relationships with cell embryo division 48 hours after fertilization. A negative association with blastocyst formation was also detected. CONCLUSION(S) Oxidative damage in the DNA is clearly increased in samples with lower sperm motility. An association between early and late embryo quality and sperm DNA oxidation supports the relevance of the hydroxylation of 8-oxoguanine as a biomarker of sperm quality reflecting the free radical damage in human sperm.

Abstract
OBJECTIVE To evaluate the embryo quality in our program for human immunodeficiency type-1 virus (HIV-1) serodiscordant couples (SDCs) with the male infected in comparison with a tubal-factor infertility control group. DESIGN Retrospective case-control study. SETTING Instituto Valenciano de Infertilidad, Valencia, Spain. PATIENT(S) Thirty SDC and 79 control couples without HIV-1 infection attending for intracytoplasmic sperm injection (ICSI). Only first cycles were considered. INTERVENTION(S) Controlled ovarian hyperstimulation and ICSI in both groups; sperm wash, nested polymerase chain reaction (PCR) in semen sample, and capacitation by swim-up after thawing the semen sample in the SDC group; and sperm capacitation by swim-up after thawing the semen sample in the control group. MAIN OUTCOME MEASURE(S) ICSI procedure and embryo characteristics (fertilization, cleavage, embryo morphology, and development) and cycle outcome (ongoing pregnancy and miscarriage rates). RESULT(S) Fertilization and cleavage rates were similar between the groups. On days 2 and 3 of embryo development, very similar embryo features were found between the groups. There was no difference in mean number of optimal embryos on day 3. When embryos were cultured up to 5-6 days, a significant increase in embryo blockage was found in the SDC group compared with the control group. The mean number of optimal blastocysts on day 6 was comparable in both groups. No difference was found regarding the number of cryopreserved and transferred embryos or implantation, pregnancy, multiple pregnancy, or miscarriage rates between the groups. CONCLUSION(S) HIV-1 infection in SDCs with infected males does not appear to have a significantly negative impact on embryo development or ICSI outcome.

Abstract
The present study determines the composition of the bio-waste fraction of waste and establishes correlations between the quality of this fraction and socio-economic/demographic variables. According to the Catalan Waste Agency [Agència de Residus de Catalunya (2004). Statistical data. Available from: <www.arc-cat.net>], the quantities of glass, paper/cardboard, light packaging and biodegradable material (those components of municipal waste that can be recovered, and have a separate collection) that were selectively collected in 2004 represent 25.6% by weight of the total municipal waste generated. There is a large spread of values from different cities. It is important to bear in mind that this percentage was calculated using the total weights of all of the materials present in the different bins used for selective solid waste collection, without taking account of the fact that many of these bins contain a certain amount of other, undesirable waste. In order to be able to determine the actual quantities that are recovered, it is necessary to establish the quality of the waste collected. To establish the quality of the waste collected, 350 samples were analysed, corresponding to the bins for the bio-waste fraction of solid waste in 193 different cities in Catalonia. Seven levels of quality were established for the study, depending on the amount of undesirable waste present. The results show certain correlations between the socio-economic/demographic factors studied and the percentage of undesirable waste present in the samples. The correlations presented here are not intended to be predictive, but rather indicative of a tendency, which should help us gain a better understanding of the behaviour of the society studied with respect to the separation of solid household waste at origin.

Abstract
AIM Partial body weight support (PBWS) is an accepted treatment for hemiplegic patients. The aim of this study is to compare the efficiency of gait trainer with conventional treatment on the gait management after stroke. METHODS Forty chronic post-stroke hemiplegics were part of a prospective research. Inclusion criteria were: first ever stroke in a chronic stage with stabilised motor deficits; age >18 and <80 years; cognitive and communication skills to understand the treatment; absence of cardiac, psychological and orthopedic contraindications. Patients were randomised into two groups: the control group (CG) that used the Bobath method in 40 minutes sessions, 5 times a week, for 5 weeks, and the experimental group (EG) that used the gait trainer, for the same period of time and frequency. Assessment tools: Motricity Index (MI); Toulouse Motor Scale (TMS); modified Ashworth Spasticity Scale (mASS); Berg Balance Scale (BBS); Rivermead Mobility Index (RMI); Fugl-Meyer Stroke Scale (F-MSS); Functional Ambulation Category (FAC); Barthel Index (BI); 10 meters, time up and go (TUG), 6 minutes, and step tests. EG and CG did the assessments before treatment (T(0)), right after treatment (T(1)), and on follow-up, 3 months later (T(2)). RESULTS CG and EG were homogenous in all the variables at T(0). CG and EG showed improvement in almost all the assessment scales after treatment, although only some with relevant differences. EG showed statistically relevant improvement on T(1) and on T(2) in several of the assessment tools, whereas CG only showed statistically significant improvement after T(1) and only in some of the assessment tools. CONCLUSIONS Both groups of chronic hemiplegic patients improved after either PBWS with gait trainer or Bobath treatment. Only subjects undergoing PBWS with gait trainer maintained functional gain after 3 months.

Abstract
Aim: The aim of the present study was to identify the risk factors, their prognostic value on multiple pregnancies (MP) prediction and their thresholds in women undergoing controlled ovarian hyperstimulation (COH) with follicle stimulating hormone (FSH) and intrauterine insemination (IUI). Methods: A case-control study was carried out by identifying in our database all the pregnancies reached by donor and conjugal IUI (DIUI and CIUI, respectively), and compared cycle features, patients' characteristics and sperm analysis results between women achieving single pregnancy (SP) versus MP. The number of gestational sacs, follicular sizes and estradiol levels on the human chorionic gonadotropin (hCG) administration day, COH length and semen parameters were obtained from each cycle and compared. Student's t-tests for mean comparisons, receiver-operator curve (ROC) analysis to determine the predictive value of each parameter on MP achievement and multiple regression analysis to determine single parameter influence were carried out. Results: Women with MP in IUI stimulated cycles reached the adequate size of the dominant follicle (17 mm) significantly earlier than those achieving SP. Also, the mean follicles number, and estradiol levels on the hCG day were higher in the CIUI and DIUI MP group. Nevertheless, only ROC curve analysis revealed good prognostic value for estradiol and follicles higher than 17 mm. Multiple regression analysis confirmed these results. No feature of the basic sperm analysis, either in the ejaculate or in the prepared sample, was different or predictive of MP. When using donor sperm, different thresholds of follicle number, stimulation length and estradiol in the prediction of MP were noted, in comparison with CIUI. Conclusions: MP in stimulated IUI cycles are closely associated to stimulation length, number of developed follicles higher than 17 mm on the day of hCG administration and estradiol levels. Also, estradiol has a good predictive value over MP in IUI stimulated cycles. The establishment of clinical thresholds will certainly help in the management of these couples to avoid undesired multiple pregnancies by canceling cycles or converting them into in vitro fertilization procedures.

Abstract
BACKGROUND Graft pancreatitis (GP) is one the main technical problems associated with pancreas transplant (PT). It occurs in 20% of patients representing a risk factor for thrombosis and cause of graft loss. GP is related to oxidative effects from oxygen-derived free radicals (OFR) in ischemia-reperfusion injury. We evaluated lipid peroxidation by the OFR in the PT of pig organs preserved with either Celsior or Wisconsin solutions. METHODS In Landrace pigs we performed 24 pancreas allografts, which were preserved 18 or 24 hours: 12 with Celsior solution (CS) and 12 with Wisconsin solution (UW). No immunosuppression was administered. The oxidative effects were determined by quantification of malondialdehyde (MDA) and 4-hydroxyalkenals (4-HDA) and of the carbonyl groups of proteins in our pancreatic tissue samples and measured at different times: (A) baseline in the donor, (B) after perfusion of the graft, (C) after the ischemia period, and (D) 30 minutes after ischemia-reperfusion of the graft. RESULTS The MDA and 4-HDA values were similar in conditions A, B, and C, but showed an extraordinary increase after ischemia-reperfusion in D, among both the 18- or 24-hour preserved grafts and in the same proportion with CS and UW. The carbonyl groups of the proteins rose in conditions B and C (cold ischemia), but less so in state D (reperfusion). CONCLUSIONS The oxidative injury of a pancreatic graft preserved for 18 or 24 hours occurs during reperfusion, with an extraordinary intensity, but similarly with CS and UW, an observation that may help to explain graft pancreatitis.

Abstract
Men who are seropositive for human immunodeficiency virus (HIV) or hepatitis C virus now can father children safely, thanks to sperm washing and nested polymerase chain-reaction techniques, followed by intracytoplasmic sperm injection. However, in a small percentage of such patients, it is impossible to recover spermatozoa after said procedures because of their highly impaired spermatogenesis. We have established that less rigorous methods, such as repeated centrifugation, yield nested polymerase chain-reaction HIV- and hepatitis C virus-negative specimens, even in sperm samples from men with severe oligoasthenozoospermia.

Abstract
OBJECTIVE To prospectively determine the impact of concrete components of the sperm oxidative glutathione stress system in terms of enzymatic activity and mitochondrial RNA (mRNA) expression on embryo quality and reproductive outcome. Human spermatozoa use the glutathione system to inactivate reactive oxygen metabolites, and there is a close correlation between some components of the glutathione system and male fertility. However, very few data are published regarding this system in sperm cells and its effect on fertilization ability and embryo development in human beings. DESIGN An oocyte-donation model, used to homogenize the female factor. SETTING University-affiliated private IVF setting. PATIENT(S) Semen samples from infertile males (n = 43) of couples undergoing oocyte-donation cycles (n = 43). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Gene expression and activity of glutathione peroxidases (GPXs) 1 and 4, glutathione reductase, and intracellular glutathione (GSH) by fluorescent quantitative polymerase chain reaction and spectrophotometry, respectively. RESULT(S) Fertilization rate, pronuclear number, asymmetry, and pronuclear body distribution were not correlated with any sperm glutathione parameters that were considered. When day 3 embryo parameters were evaluated, only GPX4 mRNA expression in sperm cells was statistically significantly lower when asymmetric embryos were observed. Also, worst embryo development and morphology on day 5 was statistically significantly correlated with lower sperm GPX1 activity (101.07 vs. 258.8 IU/mg protein). Glutathione system analysis in fresh sperm was not statistically significantly different in patients achieving pregnancy compared with those who not, and we did not find any correlation with implantation rate. CONCLUSION(S) We have been able to correlate embryo morphology on day 3 with the sperm expression of GPX family members. The results indicate that sperm-derived mRNA may condition human embryo quality and persist even to blastocyst stage. The correlation of the sperm GPX family mRNA expression with embryo health appears quite promising for discovery of molecular causes of male infertility.

Abstract
BACKGROUND There is a need for a reliable marker of endometriosis, especially in early stages of peritoneal disease during which imaging is not effective. The use of serum interleukin (IL)-6 as a marker is controversial. To readdress the matter, patients undergoing laparoscopy were prospectively evaluated for serum IL-6 levels. MATERIALS AND METHODS A total of 119 women 31 years old who underwent laparoscopy were divided into groups: control patients (n = 38) with no pathologic findings; endometriosis sufferers (n = 47) with minimal-mild (MM, n = 11) or moderate-severe (MS, n = 36) endometriosis; uterine myomas (n = 13) and benign ovarian pathologies (n = 21). Blood was drawn on cycles days 5-12 and stored for subsequent analysis of IL-6 and carbohydrate antigen (CA)-125 levels. RESULTS Serum IL-6 levels were significantly (P = 0.002) higher in women with MM endometriosis (29.4 9.0 pg/ml) than in controls (15.7 9.3 pg/ml). When all the non-endometriosis patients were grouped together (n = 72) and serum IL-6 (17.8 12.1 pg/ml) compared with MS (n = 36; 17.6 10.3 pg/ml) and MM (n = 11; 29.4 9.0 pg/ml) endometriosis significantly (P < 0.01) higher levels in MM endometriosis were observed as compared to the other two groups. Serum Ca-125 levels were significantly (P < 0.01) elevated in MS endometriosis. A serum IL-6 threshold of 25.75 pg/ml afforded a sensitivity of 75% and specificity of 83% in the diagnosis of MM endometriosis. Sensitivity and specificity for CA-125 in the diagnosis of MS endometriosis, using 35 IU/ml as the cut-off value, were 47% and 97%, respectively. CONCLUSIONS IL-6 is a reliable non-invasive marker of MM endometriosis, whereas Ca-125 is of use as a marker of severe cases.

Abstract
BACKGROUND Several evidences indicate that premature luteinization (PL) may affect IVF outcome. The primary end-point of the present study was to verify the effect of PL on the pregnancy rate (PR) of our oocyte-donation programme. METHODS PL was defined as serum progesterone > or = 1.2 ng/ml on the day of HCG. We analysed retrospectively 240 oocyte-donation cycles in which 120 women donated twice, with PL in the first donation cycle and no PL in the following one, acting as its own control. Recipients (n = 240) were divided in two groups according to the presence of PL (n = 120) or not (n = 120). Both groups were compared regarding donor cycle parameters and recipient cycle outcome. RESULTS There was no difference in PR between the groups (55.7 versus 54.4%, respectively). The number of total oocytes (18.2 +/- 0.6 versus 20.8 +/- 0.6; P = 0.003) and the number of mature oocytes retrieved (16.9 +/- 0.6 versus 19.4 +/- 0.6; P = 0.005) were different among donors with progesterone < 1.2 ng/ml and PL, respectively. There were no differences between the oocyte recipients in fertilization, cleavage, embryo division on day 3, blastocyst development or fragmentation rates. The number of embryos transferred, number of embryos cryopreserved, and implantation and miscarriage rates were similar between the groups. CONCLUSION PL does not appear to have a negative impact on ongoing PR in our oocyte-donation programme.

Abstract
OBJECTIVE Oncologic treatments can destroy spermatogenic dividing cells and cause azoospermia which could be irreversible. Sperm banking is the best option to preserve male fertility after these treatments. It is easy, inexpensive, and safe. To date, few clinical data are available about large series of cancer patients. Our objective was to determine the usefulness of these preventive sperm freezing protocols. DESIGN Prospective study. SETTING University-affiliated private fertility center. PATIENT(S) One hundred eighty-six cancer patients who banked sperm samples at our center before surgery or chemo- or radiotherapy treatments from 1991 to 2004. INTERVENTION(S) Conjugal status, age, type of cancer, treatment, and future use (if any) of the cryopreserved sperm samples for assisted reproduction technology (ART), and cycle results were recorded, analyzed, and compared with a control group. MAIN OUTCOME MEASURE(S) Basic sperm analysis of semen samples from cancer patients prior to freezing, after thawing, and after capacitation for ART. RESULT(S) A total of 320 semen samples were frozen before antineoplasic treatment. Six months later, 27% of the males recovered normal sperm production. From all frozen samples, 8.7% were discarded; the reasons were pregnancy achievement (55%), normal sperm production (28%), and patient death (18%). Finally, 5 IUI cycles and 30 ICSI cycles were done from frozen samples, with 1 and 15 pregnancies, respectively; results were comparable with those obtained in a control group. CONCLUSION(S) A significant number of males who cryopreserved semen samples before receiving antitumoral treatments have employed them. The results obtained showed that this is the strategy of choice, aiming to preserve fertility for the future, because the cost/benefit ratio is favorable. Patients should be counseled accordingly.
