RESUMO

BACKGROUND: Necrozoospermia is a condition found in 0.2%-0.4% of male infertility cases. The causes of necrozoospermia are multiple: they can be related to testicular and/or post-testicular damage. Additionally, these causes most often involve the production of reactive oxygen species (ROS) and/or sperm DNA fragmentation (SDF) which can reduce the chances of spontaneous pregnancy or affect the outcome of assisted reproductive technologies. OBJECTIVE: To focus on potential etiologies of necrozoospermia, its diagnosis and its therapeutic management especially before the employment of ICSI. METHODS: Authors searched PubMed/Medline, Web of Science, Cochrane Library, Google and Institutional websites for medical subheading terms and free text words referred to "necrozoospermia", "sperm vitality", "sperm viability", SDF and "ICSI". RESULTS: We identified 12 main etiologies of necrozoospermia responsible for either a decrease of sperm vitality, a mild, a moderate or a severe necrozoospermia. In case of a confirmed decreased vitality, a thorough check-up should be conducted and if available, etiological treatment should be proposed. Therapeutic management could also include repeated ejaculations, drug treatments, the use of ICSI with ejaculated or surgically extracted spermatozoa in case of a non-treatable necrozoospermia. DISCUSSION AND CONCLUSION: The potential causes of necrozoospermia should be investigated because many of them could be corrected, thus avoiding the use of ICSI. Moreover, if ICSI procedure remains necessary, the therapeutic management of necrozoospermia could also improve the chances of success by reducing oxidative stress and/or SDF.

RESUMO

OBJECTIVE: To evaluate the relationship between polycystic ovarian morphology (PCOM) and oocyte quality after controlled ovarian stimulation for intracytoplasmic sperm injection (ICSI). DESIGN: Prospective, comparative study with concurrently treated and age-matched controls. SETTING: Academic IVF unit of the Lille University Hospital. PATIENT(S): A total of 194 women were prospectively included before their first IVF-ICSI attempt for exclusive male infertility. They were classified into PCOM (n = 97) or control groups (n = 97) according to their follicle number per ovary. The nuclear maturation and morphologic aspects of 1,013 oocytes from PCOM patients were assessed and compared with those of 774 oocytes from controls. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Rate of metaphase II (MII) and morphologically abnormal oocytes. RESULT(S): The mean number of total and MII oocytes retrieved was significantly higher in the PCOM group. The rate of MII and morphologically abnormal oocytes was equivalent between the two groups. The mean number of embryos was significantly higher in the PCOM group. However, the percentage of top-quality embryos on day 3 was similar between the two groups. The implantation and clinical pregnancy rates were significantly higher in the PCOM group. CONCLUSION(S): Polycystic ovarian morphology does not have a negative impact on the quality of oocytes and embryos or the outcome of IVF-ICSI.

RESUMO

BACKGROUND: Morphological aspect of polycystic ovaries (PCO) is a very common finding in an IVF center population: this includes PCOS patients identified in 18-25% of the couples presenting with infertility and so called "sonographic PCO only" the prevalence of which has been estimated as high as 33% in asymptomatic patients. Finding the optimal first intention IVF protocol for polycystic ovaries patients is still challenging in order to improve the controlled ovarian hyperstimulation (COH) outcome while avoiding ovarian hyperstimulation syndrome (OHSS). It has been suggested that women with PCO would benefit from a longer period of pituitary down-regulation. The purpose of this study was to compare an extended duration of OCP pretreatment with a classic GnRH agonist protocol. METHODS: A single center prospective non-randomized study was performed from January 2009 to December 2010 in the Lille University Hospital including 113 women diagnosed with PCO(S) according to the Rotterdam ultrasonographic criteria and undergoing their first IVF attempt. Comprehensive hormonal and ultra-sonographic assessments were collected during COH in these patients. LH and androgen suppression and dynamics of follicular growth were compared between the two protocols as well as the COH outcome in terms of oocyte/embryo number and quality, implantation and pregnancy rates. RESULTS: No significant difference was observed between the two groups concerning dynamics of follicular growth and hormonal values. Clinical and ongoing pregnancy rates were significantly lower in the OCP group despite same oocyte and embryo quality. Nevertheless, the cumulative pregnancy rate did not differ between the two groups. The incidence of OHSS was not statistically significant. CONCLUSIONS: Extended duration of OCP pretreatment, as a first intention IVF protocol for PCO patients, does not improve the pattern of follicular growth nor the oocyte and embryo quality.
