DNA fragmentation severely increased. Furthermore, male factor showed an increase in T-DNAF and recurrent pregnancy loss presented morphologically normal sperm with pathological increased DNA fragmentation. We can conclude that sperm DNA evaluation provides a valuable contribution to the diagnosis of infertility in the above populations. Supported by: Institutional. P-1003 Thursday, October 17, 2013 ELECTROEJACULATION FORTHE TREATMENT OF THE ANE- JACULATORY MALE. S. W. J. Seager. National Rehabilitation Hospi- tal, Washington, DC. OBJECTIVE: We describe our experience over the last 27 years with Elec- troejaculation (EE) in neurologically impaired men. MATERIALS AND METHODS: We use a specially designed electrically isolated rectal probe with a built-in temperature monitor with a shut-off at a preset temperature. Electrostimulation is supplied for a maximum of ten minutes. Stimulation parameters range from 4-17 volts and 100-500 milli- amps. RESULTS: From 1990 to date, we have performed EE on 672 anejectory males and obtained ejaculates in all 672 for a success rate of 100%. 92% of the subjects had sperm in their ejaculate. The subjects were men who had spi- nal cord injury (SCI), complications of pelvic surgery, surgical treatment for testicular cancer, viral infections causing neurological damage, Multiple Sclerosis (MS), Spina Bifida, Diabetics, Idiopathic anejaculation caused by neurogenic or psychogenic conditions, failure to produce an ejaculate the day of collection for egg retrieval for IVF or ICSI. A new recent innovation in the use of this method of treatment is in adolescent or teenage boys with non-Hodgkins disease prior to their treatment of radiation and chemotherapy which renders them sterile. The mean age range of men with SCI was 32.1 years of age (16-61 years). For the non-SCI group it was 38.5 years (25-53 years). Sperm was present in 92% or 618 of the men who were ejaculated. No adverse effects were reported. CONCLUSION: In conclusion, EE is an effective, safe and repeatable method of sperm retrieval in neurologically impaired or other males who cannot ejaculate.

OBJECTIVE: To analyze whether there are correlations between the VEGF -1154 guanine (G)/adenine (A) polymorphism and etiopathogenic factors of DNA damage in sperm. DESIGN: Cross-sectional. MATERIALS AND METHODS: A total of 177 men were included. The DNA was extracted from peripheral blood, and the VEGF gene single nucle- otide polymorphisms (SNPs) -1154G/A were genotyped using real-time PCR with Taqman Universal PCR Master Mix and Taqman SNP genotyping as- says. At least 200 spermatozoa were examined in each semen sample (one per subject) and the following spermatozoa percentages were determined: DNA fragmentation (with TUNEL assay), abnormal chromatin packaging/ underprotamination (using chromomycin A3/CMA3), apoptosis (using an- nexin-V) and mitochondrial damage (using MitoTracker Green and JC1). All data were evaluated using c2 tests. RESULTS: VEGF genotypes with A alleles were associated with high per- centages of apoptotic spermatozoa. There was no observed association be- tween VEGF genotypes or alleles and DNA fragmentation, protamination or mitochondrial damage in sperm (Table 1). TABLE 1.

P-1006 Thursday, October 17, 2013 SPERM CHROMATIN DISPERSION (SCD) TEST IDENTIFIES MORE SPERMATOZOAWITH DNA DAMAGE THAN THE TUNEL ASSAY IN MEN WITH UNEXPLAINED INFERTILITY. C. M. Feij o, S. C. Esteves. Andrology Laboratory & Sperm Bank, ANDROFERT, Androl- ogy & Human Reproduction Clinic, Campinas, SP, Brazil. OBJECTIVE: This study aimed at comparing the TUNEL assay and the sperm chromatin dispersion (SCD) test for the determination of sperm DNA damage in men with unexplained infertility. DESIGN: Prospective comparative experimental study. MATERIALS AND METHODS: In 15 subfertile men with non-identifi- able infertility factors according to our routine investigation, sperm DNA damage was determined manually in the same semen samples using the ter- minal uridine nick-end labeling (TUNEL) assay with fluorescence micro- scopy and the SCD test with bright-field microscopy. The TUNEL assay was performed using the Apoptosis Detection TACS kit (R&D Systems, USA) while SCD was carried out using the Halosperm kit (Halotech DNA, Spain). A total of 400 cells were evaluated on each slide. Data were analyzed with Mann-Whitney and Spearman’s rank correlation. ROC analysis was performed using TUNEL as the ‘‘gold standard’’ to select possibly optimal cutpoints for assessing DNA fragmentation using SCD. RESULTS: SCD test detected a significantly higher proportion of sperm with fragmented DNA (20.6% 14.0%) than the TUNEL assay (11.5% 7.3%; P¼0.001). Receiver operating characteristic analysis revealed that 15% was the best SCD cutpoint to classify patients in the same levels of DNA fragmentation, normal or abnormal, as determined by TUNEL, with an accuracy of 70%. However, Spearman’s rank correlation showed that the methods were not comparable (r¼0.29). CONCLUSION: Our data indicate that the SCD test is more sensitive than the TUNEL assay for the assessment of DNA damage in men with unex- plained infertility. While the TUNEL assay depends on a terminal transferase to directly incorporate fluorescent UTP at single and double 3’-OH- free ends, SCD involves the combination of DNA denaturation and depletion of proteins protecting the DNA. Thus, it is important to distinguish between the methods as they deferentially evaluate sperm DNA damage. Supported by: Institutional. S438 ASRM Abstracts Vol. 100, No. 3, Supplement, September 2013
