Perdrix, Anne / Rives, Nathalie. ·Reproductive Biology Laboratory-CECOS, EA 4308 "Gametogenesis and gamete quality", IRIB, University of Rouen, Rouen University Hospital, 1 rue de Germont, 76031 Rouen Cedex, France. anneperdrix@yahoo.fr ·Hum Reprod Update · Pubmed #23825157.

ABSTRACT: BACKGROUND Approximately 10 years after the first publication introducing the motile sperm organelle morphology examination (MSOME), many questions remained about sperm vacuoles: frequency, size, localization, mode of occurrence, biological significance and impact on male fertility potential. Many studies have tried to characterize sperm vacuoles, to determine the sperm abnormalities possibly associated with vacuoles, to test the diagnostic value of MSOME for male infertility or to question the benefits of intracytoplasmic morphologically selected sperm injection (IMSI). METHODS We searched PubMed for articles in the English language published in 2001-2012 regarding human sperm head vacuoles, MSOME and IMSI. RESULTS A bibliographic analysis revealed consensus for the following findings: (i) sperm vacuoles appeared frequently, often multiple and preferentially anterior; (ii) sperm vacuoles and sperm chromatin immaturity have been associated, particularly in the case of large vacuoles; (iii) teratozoospermia was a preferred indication of MSOME and IMSI. CONCLUSION The high-magnification system appears to be a powerful method to improve our understanding of human spermatozoa. However, its clinical use remains unclear in the fields of male infertility diagnosis and assisted reproduction techniques (ARTs).

2 Review [ICSI treatment in severe asthenozoospermia]. 2012

Mitchell, V / Sigala, J / Jumeau, F / Ballot, C / Peers, M C / Decanter, C / Rives, N / Perdrix, A / Rigot, J-M / Escalier, D. ·EA4308 gamétogenèse et qualité du gamète, 59037 Lille cedex, France. valerie.mitchell@chru-lille.fr ·Gynecol Obstet Fertil · Pubmed #23182233.

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.

3 Article The feasibility of fertility preservation in adolescents with Klinefelter syndrome. 2013

Rives, N / Milazzo, J P / Perdrix, A / Castanet, M / Joly-Hélas, G / Sibert, L / Bironneau, A / Way, A / Macé, B. ·Laboratoire de Biologie de la Reproduction-CECOS, Rouen University Hospital, Rouen, France. nathalie.rives@chu-rouen.fr ·Hum Reprod · Pubmed #23539613.

ABSTRACT: STUDY QUESTION: Is fertility preservation feasible after the onset of puberty in adolescents with Klinefelter syndrome (KS)? SUMMARY ANSWER: Fertility preservation counseling should be an integral part of the care of XXY adolescents. Frozen ejaculated or testicular spermatozoa and even frozen immature germ cells can give them the potential to conceive their genetic progeny. However, no biological or clinical parameters were predictive of mature or immature germ cell retrieval. WHAT IS KNOWN ALREADY: KS is the commonest sex chromosome disorder observed in azoospermic infertile males. Testicular sperm extraction success decreases with age and after testosterone therapy. Arguably, spermatozoa should be retrieved from KS males at the onset of puberty and before testosterone therapy to increase the chance of success. STUDY DESIGN, SIZE, DURATION: A retrospective study was performed in eight KS adolescents, aged between 15 and 17 years, who were referred for counseling about their future fertility to the center CECOS (Centre d'Etude et de Conservation des Oeufs et du Sperme humain) at Rouen University Hospital between October 2008 and December 2011. PARTICIPANTS/MATERIALS, SETTING, METHODS: The patients were first seen with their parents and then separately. It was proposed to them that they should provide a semen sample, if this was azoospermic, two other semen samples spaced by 3 months were collected. If azoospermia was confirmed, a bilateral testicular biopsy was proposed for sperm retrieval and testicular tissue preservation. Each adolescent met the psychologist before undergoing testicular biopsy. Paraffin-embedded testicular tissue was evaluated after staining with hematoxylin-eosin and saffron and immunostaining using vimentin, anti-Müllerian hormone, androgen receptor and MAGE-A4 antibodies. Sertoli cell maturity, germ cell identification and lamina propria alteration were assessed on seminiferous tubules. MAIN RESULTS AND THE ROLE OF CHANCE: KS adolescents were not deeply concerned about their future fertility and only became involved in the process of fertility preservation after at least three medical consultations. The parents agreed immediately that fertility preservation should be attempted. Seven non-mosaic XXY adolescents presented with azoospermia and one XXY/XY adolescent had oligozoospermia. Increased plasma levels of FSH and LH as well as bilateral testicular hypotrophy were observed in all patients. The XXY/XY adolescent banked four semen samples before testosterone replacement therapy. Two patients refused testicular biopsy. Five patients accepted a bilateral testicular biopsy. Spermatozoa were retrieved in one patient, elongated spermatids and spermatocytes I in a second patient. LIMITATIONS, REASONS FOR CAUTION: The number of patients enrolled in our study was low because the diagnosis of KS is only rarely made before or at the onset of puberty. Most XXY males are diagnosed in adulthood within the context of male infertility. WIDER IMPLICATIONS OF THE FINDINGS: Spermatozoa can be retrieved in semen sample and in testicular tissue of adolescent Klinefelter patients. Furthermore, the testis may also harbor spermatogonia and incompletely differentiated germ cells. However, the physician should discuss with the patient and his parents over a period of several months before collecting a semen sample and performing bilateral testicular biopsy. Fertility preservation might best be proposed to adolescent Klinefelter patients just after the onset of puberty when it is possible to collect a semen sample and when the patient is able to consider alternative options to achieve fatherhood and also to accept the failure of spermatozoa or immature germ cell retrieval.

4 Article Modification of chromosomal architecture in human spermatozoa with large vacuoles. 2013

Perdrix, A / Travers, A / Clatot, F / Sibert, L / Mitchell, V / Jumeau, F / Macé, B / Rives, N. ·Biology Laboratory-CECOS, EA 4308 Spermatogenesis and male gamete quality, Rouen University Hospital, Rouen Cedex, France. anne.perdrix@chu-rouen.fr ·Andrology · Pubmed #23258631.

ABSTRACT: Human normal spermatozoa present a specific chromatin organization, illustrated particularly by the non-random chromosome positioning. Spermatozoa with large vacuoles, described using motile sperm organelle morphology organization (MSOME), are associated with nuclear alterations, such as abnormal chromatin condensation and aneuploidy. To question a probable association between large nuclear vacuoles and chromatin disorganization, we evaluated chromosomes X, Y and 18 topography in normal spermatozoa (NS) compared with spermatozoa with large vacuoles (SLV). After centrifugation on a gradient density system, 229 NS (spermatozoa presenting a normal nuclear shape and a vacuole area <6.5% of head area) from 10 normal semen samples and 221 SLV (spermatozoa presenting a vacuole area >13% of head area) from 10 semen samples with teratozoospermia were selected using MSOME. A three-colour FISH was carried out using α-satellite centromeric probes for chromosomes X, Y and 18. For each chromosome, longitudinal and spatial positioning of centromeres was analysed. Distribution of each chromosome was non-random in NS and in SLV, whatever the methodology used. Using longitudinal positioning, distribution of chromosome 18 and chromosome Y centromeres did not differ significantly between SLV and NS. On the contrary, chromosome X centromeres were more frequently positioned in the posterior region of sperm nucleus in SLV (p = 0.01). Considering spatial positioning, distributions differed significantly between SN and SLV for chromosome Y (p = 0.02) and chromosome 18 (p < 10(-4) ) and marginally for chromosome X (p = 0.08). Our study concluded to a modification in chromosomes X, Y and 18 centromere topography between NS and SLV, representing a novel and supplementary evidence to argue chromatin disorganization in SLV.

5 Article [Prognosis factors in donor semen insemination: a 10-years follow-up study of 188 patients]. 2013

Mokdad, C / Clavier, B / Perdrix, A / Roman, H / Marpeau, L / Rives, N. ·Clinique gynécologique et obstétricale, CHU Charles-Nicolle, 1, rue de Germont, 76031 Rouen cedex, France. cecile.mokdad@gmail.com ·Gynecol Obstet Fertil · Pubmed #22989519.

ABSTRACT: OBJECTIVES: Improving our practice by a constant evaluation is essential in the field of donor semen insemination (DI). Our center examined the prognosis factors for DI success in order to standardize patient treatment options. PATIENTS AND METHODS: We retrospectively analysed all couples referred for DI from January 2000 till December 2010. RESULTS: We analysed 551 cycles among 188 patients. Pregnancy rate by stimulation cycle was 19,8% with birth rate of 16.7%. The rate of pregnancy was improved till the fourth trial then plateau. On a patient-based analysis, success factors were age (P=0.04), previous successful DSI (P=0.02), and no previous failure of an ICSI-C (P=0.035). On a cycle-based analysis, success factors were the number of follicles greater than 15mm (P=0.04) and than 18mm (P=0.001). The percentage of 68.1 patients obtained a child by IVF-D after a failed DI. CONCLUSION: There are two predictive factors for DI success: the age of the patient and the number of mature follicles. It seems accurate to referred patients to IVF-D after four unsuccessful cycles of DSI. This recommendation may be adapted according to patient's age and hormonal evaluation.

6 Article [Male gamete…spermatozoon or spermatid?]. 2012

Rives, N / Milazzo, J P / Arkoun, B / Travers, A / Perdrix, A / Bironneau, A / Macé, B. ·Laboratoire de biologie de la reproduction, CECOS, EA 4308 gamétogenèse et qualité du Gamète, IRIB, Université de Rouen, CHU hôpitaux de Rouen, CHU Charles-Nicolle, 1, rue de Germont, 76031 Rouen cedex, France. nathalie.rives@chu-rouen.fr ·Gynecol Obstet Fertil · Pubmed #23102576.

ABSTRACT: Normal spermatogenesis results from a balance between process of cell proliferation, cell differentiation and apoptosis that concern somatic cells and germ cells. Dysfunction of spermatogenesis may be the result of constitutional or acquired abnormalities of spermatogonia stem cells or somatic cells. To overcome these problems, it seems necessary to implement preventive measures for germ stem cell preservation or substitute measures to replace them, the objective being to replicate in vivo or in vitro the process of spermatozoa production. This article will discuss the different experimental strategies for considering the in vivo or in vitro production of spermatozoa, outside the physiological process.

7 Article Relationship between conventional sperm parameters and motile sperm organelle morphology examination (MSOME). 2012

Perdrix, A / Saïdi, R / Ménard, J F / Gruel, E / Milazzo, J P / Macé, B / Rives, N. ·EA 4308 Spermatogenesis and male gamete quality, Reproductive Biology Laboratory-CECOS, Rouen University Hospital, Rouen Cedex, France. nathalie.rives@chu-rouen.fr ·Int J Androl · Pubmed #22420485.

ABSTRACT: With the motile sperm organelle morphology examination (MSOME), spermatozoa morphology may be assessed directly on motile spermatozoa at high magnification (up to 6600×). This procedure describes more precisely spermatozoa abnormalities, especially head vacuoles. However, no consensus has been established concerning normal or abnormal MSOME criteria. The aim of our study was to define MSOME vacuole criteria assessed objectively with a digital imaging system software to establish a potential relationship between conventional semen parameters. A total of 440 semen samples were obtained from males consulting in Rouen University Hospital Reproductive Biology Laboratory. Conventional semen analysis (volume, sperm concentration, progressive motility, vitality and morphology) and MSOME assessment {sperm head length, width and area as well as vacuole number, vacuole area and relative vacuole area to sperm head [RVA (%) = [vacuole area (μm(2))/head area (μm(2))] × 100)]} were performed for each semen sample. Among our 440 males, 109 presented normal conventional semen parameters and 331 abnormal ones. Sperm head vacuoles were significantly larger in abnormal semen samples (p < 0.0001). RVA was the most discriminative MSOME criterion between normal and abnormal semen samples according to ROC curves analysis, and was negatively correlated with poor sperm morphology (r = -0.53, p < 0.0001). We concluded to (i) the normal occurrence of vacuoles in sperm head whatever the normality or abnormality of semen parameters, (ii) the discriminative function of the RVA to distinguish semen samples with normal and abnormal parameters, and (iii) the strong correlation between high RVA and poor sperm morphology.

8 Article Concomitant unilateral and synchronous bilateral testis cancer in azoospermic dizygotic twins: differential management of fertility preservation. 2011

Safsaf, Athmane / Sibert, Louis / Cleret, Jean-Marc / Perdrix, Anne / Milazzo, Jean-Pierre / Gobet, Françoise / Mace, Bertrand / Rives, Nathalie. ·Service d'Urologie, Spermatogenèse et qualité du gamète mâle, Hôpital Charles Nicolle, Rouen, France. athmane.safsaf@gmail.com ·Fertil Steril · Pubmed #21377156.

ABSTRACT: OBJECTIVE: To optimize fertility preservation management in unilateral or bilateral testicular cancer. DESIGN: Case series. SETTING: Urology department and reproductive biology laboratory. PATIENT(S): Dizygotic azoospermic twins presenting unilateral and bilateral synchronous testicular tumors. INTERVENTION(S): Testicular sperm extraction (TESE) and orchiectomy. MAIN OUTCOME MEASURE(S): Semen analysis, histologic diagnosis. RESULT(S): No spermatozoa were cryopreserved for the first case, because fertility preservation was proposed after orchiectomy. Spermatozoa were retrieved after TESE for his brother with bilateral tumor. CONCLUSION(S): Clinicians should be aware of the need to recommend sperm banking before treatments may alter spermatogenesis. TESE may be the sole option for fertility preservation in bilateral testicular cancer.

9 Article Assessment of acrosome and nuclear abnormalities in human spermatozoa with large vacuoles. 2011

Perdrix, A / Travers, A / Chelli, M H / Escalier, D / Do Rego, J L / Milazzo, J P / Mousset-Siméon, N / Macé, B / Rives, N. ·EA 4308 Spermatogenesis and Male Gamete Quality, Reproductive Biology Laboratory-CECOS, Rouen University Hospital, University of Rouen, Rouen, France. ·Hum Reprod · Pubmed #21088015.

ABSTRACT: BACKGROUND: Spermatozoa with large vacuoles (SLV) may have a negative impact on embryo development. The origin of these vacuoles is unknown. We evaluated acrosome and nucleus alterations in isolated SLV, versus unselected spermatozoa. METHODS: We studied 20 patients with teratozoospermia. Spermatozoa from the native semen sample and spermatozoa presenting a vacuole occupying >13.0% total head area, isolated under high magnification (×6600), were assessed. Confocal and transmission electron microscope evaluations were performed on SLV and native sperm, respectively. Acrosome morphology and DNA fragmentation were analysed using proacrosin immunolabelling (monoclonal antibody 4D4) and terminal deoxynucleotidyl transferase-mediated dUTP nick end labelling assay. Chromatin condensation was evaluated with aniline blue staining. Sperm aneuploidy was assessed using fluorescence in situ hybridization. RESULTS: SLV represented 38.0 ± 5.10% of motile spermatozoa obtained after gradient density centrifugation. Vacuoles were mainly in the anterior and median sperm head (45.7 ± 2.90 and 46.1 ± 3.00%, respectively). Abnormal acrosomes were increased in SLV compared with unselected spermatozoa (77.8 ± 2.49 versus 70.6 ± 2.62%; P = 0.014). Microscopic observations showed an exclusively nuclear localization of large vacuoles. Complete DNA fragmentation was higher in native spermatozoa (P < 0.0001) than SLV, while chromatin condensation was altered in SLV (P < 0.0001). Aneuploidy and diploidy rates were increased in SLV (P < 0.0001). CONCLUSIONS: Sperm vacuoles were exclusively nuclear. In our selected teratozoospermic population, aneuploidy and chromatin condensation defects were the main alterations observed in SLV. Based on results from this small sample of spermatozoa, we propose a global impairment of the spermatogenesis process as a common origin of the morphological alterations.
