Abstract
The decapitated sperm defect is a rare type of teratozoospermia responsible for male infertility. Spermatozoa from patients affected by this syndrome are used for intracytoplasmic sperm injection (ICSI) although little is known about their DNA integrity. This study evaluated sperm nuclear alterations in four patients and ten fertile men (control group). Sperm samples were examined by light, transmission electron and high-magnification contrast microscopy and analysed after terminal deoxynucleotidyltransferase-mediated dUTP nick end labelling, aniline blue staining and fluorescence in-situ hybridization. Spermatozoa from patients presented varying degrees of decapitation, along with morphological and ultrastructural head abnormalities. Whereas the proportion of spermatozoa with fragmented DNA and numerical chromosome abnormalities was similar in patients 1-3 and controls, the percentage of spermatozoa with hypocondensed chromatin was higher in patients 1-3 than in fertile men. Patient 4 presented a distinct phenotype, with an increased proportion of flagellated spermatozoa with DNA strand breaks as well as increased aneuploidy and diploidy rates compared with controls and with patients 1-3. No successful pregnancy resulted from ICSI although embryos were obtained for three patients. The morphological defects and the nuclear alterations observed in spermatozoa of patients with the decapitated sperm syndrome may have contributed to ICSI failures.

Abstract
BACKGROUND The value of varicocele repair and the latter's impact on semen parameters are still subject to debate. METHODS We analyse changes over time in initially abnormal sperm parameters and serum concentrations of testosterone, FSH and inhibin B after embolization treatment of males with high-grade varicocele. From 2007 to 2012, we recruited 47 male infertile patients with clinically visible left varicocele in the resting patient and at least one abnormal semen parameter. Sperm parameters and serum levels of total testosterone, FSH and inhibin B were measured prior to retrograde embolization (M0) and then 3 (M3) and 6 (M6) months afterwards. RESULTS At M0, the median sperm concentration was 5.78 [0.84-37.70] × 10(6)/ejaculate. The mean ± SD sperm progressive motility, vitality and percentage of normal sperm were respectively, 21.83 ± 16.48%, 61.88 ± 15.98% and 12.88 ± 7.15%. The corresponding values at M3 were significantly higher (38.75 [3.96-95] × 10(6)/ejaculate, 29.32 ± 14.21%, 69.14 ± 14.86% and 19.03 ± 11.02%, respectively). The mean percentage of spermatozoa with a thin head was significantly lower at M6 (6.35 ± 5.29%) than at M0 (14.03 ± 13.09%). The mean serum testosterone, FSH and inhibin B levels did not change significantly over time. CONCLUSIONS Embolization treatment in men with clinically visible left varicocele, abnormal sperm parameters and documented infertility is associated with a significant improvement in semen parameters including sperm head morphology.

Abstract
Although electron microscopy provides a detailed analysis of ultrastructural abnormalities, this technique is not available in all laboratories. We sought to determine whether certain characteristics of the flagellum as assessed by light microscopy were related to axonemal abnormalities. Forty-one patients with an absence of outer dynein arms (type I), a lack of a central complex (type III) and an absence of peripheral doublets (type IV) were studied. Sperm morphology was scored according to David's modified classification. Flagella with an irregular thickness were classified as being of normal length, short or broken. There were correlations between missing outer dynein arms and abnormal, short or coiled flagellum. Type III patients showed the highest flagellar defects (a short (P = 0.0027) or an absent flagellum (P = 0.011)). Just over 68% of the irregular flagella were short in Type III patients, whereas this value was only 34.5% in type I and 26.4% in type IV (P = 0.002). There was a negative correlation between misassembly and spermatozoa of irregular flagella (r = -0.79; P = 0.019). It is concluded that light microscopy analysis of flagellum abnormalities may help provide a correct diagnosis, identify sperm abnormalities with fertility potentials and outcomes in assisted reproduction technologies and assess the genetic risk.

Abstract
In the management of asthenozoospermia, the spermogram-spermocytogram plays an important role during diagnosis. It is of major importance to distinguish between necrozoospermia and sperm vitality. An ultrastructural study of spermatozoa is processed in the case of primary infertility without female implication, severe, unexplained and irreversible asthenozoospermia, sperm vitality at least 50 % and normal concentration of spermatozoa. Ultrastructural flagellar abnormalities are numerous and involve most spermatozoa. ICSI provides a suitable solution for patients with sperm flagellar defects to conceive children with their own gametes but the rate of ICSI success may be influenced by the type of flagellar abnormality. Some fertilization and birth rate failures which are related to some flagellar abnormalities might occur.

Abstract
Azoospermia may be obstructive (blockage of the genital ducts) or non-obstructive (a lack of testicular production). The distinction is based on an ensemble of clinical, spermiological, hormonal, ultrasound, genetic and histological data. Azoospermia is the main indication for testicular biopsy for therapeutic and diagnostic purposes. Testicular spermatozoids are processed in the reproductive biology laboratory (simultaneously with oocyte retrieval or not) for in vitro fertilization with intra-cytoplasmic sperm injection. The histological study of spermatogenesis is usually performed on a testicular biopsy sample taken at the same time and provides additional diagnostic information on infertility. Histological alterations in the testicular tissues are frequently observed in azoospermic men. In non-obstructive azoospermia, three histological situations prevail: hypospermatogenesis, Sertoli-cell-only syndrome and germ cell arrest. One can distinguish between pure forms (in which all the seminiferous tubules have the same appearance) and mixed forms (in which the tubules' aspects are heterogeneous). Hypospermatogenesis is highly prevalent in azoospermia and is characterized by a low, basal level of spermatozoid production. The prevalence of Sertoli-cell-only syndrome varies from 27 to 68% and the mean spermatozoid recovery rate is between 16 and 33%. Germ cell arrests are rare phenotypes and have a poor prognosis for spermatozoid recovery. Overall, histological examination (still the only way to fully describe spermatogenesis) must be qualitative and quantitative, with the adoption of a standardized, universally understood terminology. It is essential to compare the histological data with (i) recovery of testicular spermatozoids, (ii) clinical, ultrasound, hormonal and genetic data and (iii) the outcome of IVF/ICSI procedures.

Abstract
BACKGROUND Severe sperm motility impairment results in human infertility, which can be overcome by ICSI. Whether some particular, possibly genetic, flagellar abnormalities can influence embryonic development is a matter of debate. METHODS Analysis of ultrastructural flagellar abnormalities and ICSI outcomes with ejaculated spermatozoa in a series of 21 infertile patients with asthenozoospermic or dyskinetic spermatozoa due to a primary and specific flagellar abnormality was carried out. RESULTS Patients were sorted into six categories according to flagellar ultrastructural defects. Oocyte fertilization occurred in the 21 couples with a mean 2PN fertilization rate reaching 61.85%. No difference was observed in the kinetics of in vitro development or in the morphological quality of the embryos between the different types of flagellar abnormalities. Pregnancy occurred in 12 couples (57.1%) and delivery in nine couples (42.86%). Both the implantation rate and the clinical pregnancy rate per cycle were lower in type III abnormalities and in patients with an initial sperm motility less than 5%. CONCLUSIONS The rate of ICSI success may be influenced by the type of flagellar abnormality. ICSI provides a suitable solution for patients with sperm flagellar defects but raises the question of the consequences of a specific (and primary flagellar) abnormality on oocyte fertilization, on embryo and fetal development as well as on live birth.

Abstract
The relationship between peptidergic neurites and paired helical filaments (PHF)-positive neurites in Alzheimer's disease (AD) senile plaques (SP) was studied using combined fluorescence and bright field optics. Cryostat sections of AD hippocampi were first stained by thioflavine-S and immunolabeled with antisera raised against different neuropeptides: somatostatin 28(1-12) (som 28(1-12)), somatostatin 14 (som 14), neuropeptide Y (NPY), cholecystokinin (CCK) and substance P (sP). Secondly, using the elution-restaining procedure, sections were immunolabeled with anti-tau/PHF. In immature SP, clusters of abnormal, swollen neurites were found. The dystrophic, strongly peptidic-positive neurites contained less PHF than the poorly positive ones. Cell bodies, exhibiting a peptidic content, could be found within SP without any alteration. These results suggest the following sequence of events: an extracellular poisoning mechanism, perhaps the amyloid substance, first changes the structure of presynaptic endings and causes the formation of ballooning dystrophic neurites filled with their normal peptidic content. Subsequently, intracellular degradation occurs with formation of the PHF. Then the other structures such as dendrites and perikarya are damaged by the same mechanism. Therefore this phenomenon seems to precede any formation of PHF in SP.

Abstract
We studied the organization of dystrophic neurites around pathological vessels in Alzheimer cortex. Two techniques were used simultaneously on serial sections: thioflavine staining of amyloid substance and immunohistochemistry with immune sera against Paired Helical Filaments (anti-PHF) and native Tau proteins (anti-Tau). We observed different distributions of dystrophic neurites (immunolabelled with anti-PHF or anti-Tau) around thioflavine-stained angiopathic arterioles. The wall of the vessels with large diameter (greater than 100 microns) presented a congophilic angiopathy without neuropil reaction. In vessels with lesser diameter (less than 100 microns), dystrophic neurites constituted a discontinuous sleeve around vessels, always in close contact with amyloid substance outside the wall (dysphoric angiopathy). We observed structures similar to senile plaques around capillaries (diameter: 10-15 microns). The sleeve of dystrophic neurites with aggregated Tau proteins were always observed in the close vicinity of the amyloid substance which exuded from the pathological blood vessels. Thus, the exudation of these amyloid fibrils seems to induce the formation of dystrophic neurites (neuritic reaction).

Abstract
Two main techniques are used to stain the three types of brain lesions characteristic of Alzheimer's disease: Neurofibrillary tangles (NFT), senile plaques (SP) and congophilic angiopathy. Thioflavine-S is an histochemical marker of the amyloid substance located essentially in the central core of senile plaques and in the walls of the pathological blood vessels. Specific antibodies against Paired Helical Filaments (PHF), the ultrastructural elements of NFT, reveal neuron cell bodies with NFT and numerous dystrophic neurites, mostly around neuritic plaques. Using simultaneous histochemical and immunohistochemical labellings on the same tissue sections of Alzheimer cortex (association cortex and hippocampus), the different lesions were stained with great sensitivity and specificity. Moreover, an unusual morphological relationship between two types of lesions was detected in two Alzheimer brains with prominent congophilic angiopathy: we observed a well marked concentration of dystrophic neurites, immunolabelled with anti-PHF, around blood vessels with Thioflavine-S stained amyloid angiopathy. These lesions were distributed like a sleeve around 1/10 of dyshoric or congophilic blood vessels. The significance of such lesions is unknown but they probably represent a step of the pathogenesis of Alzheimer brain lesions and may explain the general mechanism of lesion formation in Alzheimer's disease.
