Full textThe involvement of aromatase in the quality of the spermatozoa was undertaken in Tunisian patients with abnormal mobility and morphology spermatozoa and undergoing infertility assessment. A significant decrease of aromatase transcript was noted in both teratozoospermia and asthenoteratozoospermia groups compared with normozoospermia. Asthenozoospermia group was divided into two sub-groups with aromatase mRNA rates lowered in the first and increased in the second. Moreover, a significant correlation between mRNA aromatase and the percentage of sperm morphology and/or MAI was recorded. The seminal plasma biochemical parameters in these patients revealed a significant reduction of fructose level in the asthenozoospermic in comparison with asthenoteratozoospermic patients. The correlation analysis reveals that neutral a- glucosidase is correlated with seminal volume and pH; citric acid with pH and fructose with seminal volume, sperm count and morphology. The implication of aromatase and estrogen receptor alpha gene in the sterility of chromosomal hybrid mice resulting from crosses between Robertsonian (22Rb) 2n = 22 and standard (40Std) 2n = 40 domestics mice was verified by the analysis of the expression of aromatase and estrogens receptor alpha genes. Our data showed no difference of mRNA rates of these two markers in the testes between hybrids and parental races but, in females a reduced level of aromatase ARNm was observed in the ovaries of hybrids resulting from the cross (♀40Std×♂22Rb)

Full textThe male infertility seems to increase for several decades. Infertility etiologies are multiple, but the genetic and epigenetic causes are important. Here, we tried to study, the abnormalities carried by spermatozoa and sometimes transmissible in the conceptus. This work contains three parts, in a first time, the infertility linked with abnomalities of constitutionel karyotype by studying the consequences for the chromosomal risk with the risk estimated on all spermatozoa, in a second time, the infertility, with normal constitutionel karyotype, where the genetic origin was sometimes demonstrated and sperm morphology altered with macrocephalic sperm, Globozoospermia and spermatozoa with large or small vacuoles and in fine, DNA methylation abnormalities in various azoospermic aetiologies. These approaches have a triple interest because, it estimate the risks for conceptus and advice patients care, guide the choice of spermatozoa to be injected in the oocyte

Full textInfertility affects about 15% of couples with male factor found in half of the cases. This Ph.D thesisinvestigates three causes of male infertility including chromosomal abnormality, genetic disorderand factors related to alterations in sperm DNA quality. The thesis is organized into two parts.In the first part, the chromosomal equipment and sperm DNA fragmentation in gametes of infertilemen were assessed by FISH and TUNEL. On the one hand, a high rate of aneuploid gametes andsperm DNA fragmentation were observed in four patients with gonosomal mosaicism. On the otherhand, analysis of chromosomal equipment and sperm nuclear DNA in each gamete from 13 patientswith structural chromosome abnormalities showed that unbalanced gametes have more fragmentedDNA than normal or balanced ones.In the second part, a technique for analysing the transcriptome in spermatozoa was developed onfresh and frozen semen. In fact, the combination of a discontinuous density gradient and a somaticcell lysis solution makes it possible to completely eliminate somatic cells and to recover as manysperms in the semen as possible. The XS NucleoSpin RNA kit (Macherey Nagel) was found to bemore suitable for RNA extraction than the RNA extraction kit from Qiagen. The purity of sperm RNA was verified by both RT-PCR and the Bíoanalyzer 2100. These two methods have yieldedsimilar and consistent results. The microarray analysis showed that fresh sperms do not share thesame gene expression profile than frozen ones

Full textThe majority of genes on the X chromosome are repressed during meiosis and only 6% of them are expressed in post meiotic germ cells. One of these genes is Ubal, encoding the ubiquitin-activating enzyme UBA1. Ubal produces three different transcripts, two of which are ubiquitously expressed while the third is predominant in the post meiotic germ cells: the spermatids. Our study shows that the 5’UTR, which is the only difference between these transcripts, determines the localization and the relative dose of the nuclear and cytoplasmic isoform of the UBA1 protein. The spermatid-specific transcript encodes for the nuclear isoform in the spermatids in the mouse suggesting that the UBA1 protein is implicated in chromatin remodeling during spermiogenesis. We have detected two mutations in the spermatid-specific region of the UBA1 gene in two infertile men: a deletion of 13bp and a G>A transition, neither of which was found in our cohort of fertile men. The deletion of 13bp diminishes the correct splicing of the spermatid-specific transcript and that the G>A transition may reduce expression of the spermatid-specific transcript. These results show that the UBA1 gene is involved in spermiogenesis, and reactivated in spermatids by its spermatid-specific transcript and that the mutations identified may induce infertility by reducing UBA1 levels in spermatids. We have also demonstrated that two variants described in the protamine codant gene PRM1C.102G>T and c.-107G>C are clearly not associated with male infertility and that the c.-107G>C is polymorphism frequently found in the congolese population

Full textInfertility is currently considered by the World Health Organization (WHO) as a major health concern affecting more than 50 million couples worldwide. In western countries, the majority of infertile couples seek assisted reproductive technologies (ART) to achieve a pregnancy. Despite the success of these techniques, almost half of these couples fail to obtain a child. Part of these failures are explained by the alteration of gametogenesis. In humans, spermatogenesis involves hundreds of genes specifically expressed in the testis. The abundance of these genes suggests that spermatogenic defects are associated with a strong genetic component. Recently, technical advances have led to the identification of numerous causative genes, but the vast majority of male infertility cases remain idiopathic. The aim of the present thesis is to identify new genetic causes responsible for male infertility and to elucidate the physiopathological mechanisms associated with these anomalies.During my thesis, I participated with the team GETI (genetics, epigenetics and therapies of infertility) in the genetic exploration of two phenotypes of male infertility related to post-meiotic defects of spermatogenesis: a rare form of non-obstructive azoospermia and the phenotype of multiple morphological abnormalities of the sperm flagella (MMAF). I have also played a key role in creation and analysis of transgenic mice to better characterize the pathogeny of the identified genetic causes in Human.Genetic analyses performed on two infertile brothers born form consanguineous parents and presenting an-idiopathic non-obstructive azoospermia associated with a post-meiotic arrest of spermatogenesis allowed us to identify a homozygous variant in the SPINK2 gene that encodes a serine-protease inhibitor. Phenotypic analysis of Spink2-/- adult male mice showed that they are infertile and perfectly mimic the sperm and testicular phenotypes observed in our patients. We showed that Spink2 protein is expressed from the round spermatid stage and localized in the acrosome, a lysosomal-like vesicle rich in proteases that play a key role during fertilization. When Spink2 is absent, the deregulated proteolytic activity of the targeted proteases such as acrosin leads to the fragmentation of the Golgi apparatus and arrest of spermiogenesis at the round spermatid stage. We also showed that sperm from heterozygous human and mice present a high level of morphological abnormalities and a decrease of progressive motility leading to a variable subfertility. These results showed for the first time that oligo-teratozoospermia and azoospermia could present a pathological continuum due to the same pathogeny.We also performed exome sequencing in a cohort of 78 non related MMAF subjects and identified in 49 cases deleterious bi-allelic mutations in a total of 11 candidate genes including DNAH1, CFAP43, CFAP44, WDR66 and FSIP2 giving a genetic diagnosis yield of 63%. These results confirm the genetic heterogeneity of MMAF and the efficiency of high throughput sequencing in genetic exploration of this phenotype. We also demonstrated the pathogenic implication of certain candidate genes (n=4) using knock-out mice created by the new technology of genome editing, CRISPR/Cas9.Overall, this work demonstrates the interest and effectiveness of combining exome sequencing and CRISPR/Cas9 system to study spermatogenesis disorders and male infertility

Full textMale infertility affects more than 20 million men worldwide and represents a major health concern. Although multifactorial, male infertility has a strong genetic basis which has so far not been extensively studied. The objectives of my thesis were to initiate and conduct some genetic investigations on three specific phenotypes of teratozoospermia: macrozoospermia, globozoospermia and multiple morphological abnormalities of the flagella (MMAF).For the first phenotype, we studied 87 patients with macrozoospermia, including 83 index cases, and identified c.144delC, a pathogenic mutation in the AURKC gene in 82% of patients (68/83) confirming that this variant is the main cause of macrozoospermia. A new recurrent mutation, p.Y248*, leading to degradation of the mutant transcripts by non-sense mediated mRNA decay was identified in 10 unrelated patients. Patients with no identified AURKC mutation have a decreased rate of spermatozoa with a large head and multiple flagella. Identification of two ancestral mutations in AURKC maintained during evolution despite their negative effect on reproduction in homozygous men, raises the question of a potential selective advantage provided by the AURKC haploinsufficiency.For the second phenotype, we first analyzed 34 patients presenting with globozoospermia using MLPA (multiplex ligation-dependent probe amplification) and Sanger sequencing. In total, 22 of the 30 unrelated patients where homozygous for the DPY19L2 deletion (73.3%) and 3 novel point mutations were identified. These results suggest that the molecular investigation of the DPY19L2 gene in globozoospermic patients should not be limited to the detection of the DPY19L2 genomic deletion and open interesting perspectives for the identification of DPY19L2 partners during acrosome biogenesis. Subsequently, we demonstrated that the genomic deletion was mediated by Non-Allelic Homologous Recombination (NAHR) between two homologous 28-Kb Low Copy Repeats (LCRs) located on each side of the gene. The vast majority of genomic breakpoints fell within a 1.2-Kb region central to the 28-Kb LCR. A 13-mer consensus sequence is located in the centre of that 1.2-Kb region recognized by PRDM9, a multi-unit zinc finger binding protein that promotes the formation of double-strand breaks (DSBs) initiating the homologous recombination process. The accepted theoretical NAHR model predicts that during meiosis, NAHR produces more deleted than duplicated alleles. Surprisingly, array-CGH data show that, in the general population, DPY19L2 duplicated alleles are approximately three times as frequent as deleted alleles. In order to shed light on this paradox, we developed a sperm-based digital PCR to measure the de novo rates of deletions and duplications at this locus. As predicted by the NAHR model, we identified an excess of de novo deletions over duplications. These discording results may be explained by the purifying selection against sterile, homozygous deleted men. Heterozygous deleted men might also suffer a small fitness penalty.Lastly, for the third phenotype, homozygosity mapping was carried out on a cohort of 20 North African individuals, presenting with primary infertility resulting from impaired sperm motility caused by a mosaic of multiple morphological abnormalities of the flagella (MMAF). Five unrelated subjects out of 18 (28%) carried a homozygous variant in DNAH1, which encodes an inner dynein heavy chain and is expressed in testis. RT-PCR and immunostaining studies confirmed the pathogenic effect of one of these mutations located on a donor splice site. Electronic microscopy revealed a general axonemal disorganization including mislocalization of the microtubule doublets and loss of the inner dynein arms suggesting that DNAH1 plays a critical role in sperm flagellum biogenesis and assembly

Full textThe study of an infertile male population seeking for Assisted Reproductive Technology is reported. Molecular study of the long arm of the Y chromosome, in AZF region, shows a relatively high ftequency of microdeletions, reflecting and confirming the interest of such an analysis in severe unexplained male infertility. Complete AZFa deletions are detected with a higher ftequency compared to literature data, essentially in non-obstructive azoospermia. Moreover, partial AZFb and AZFc deletions are detected: partial ptoximal AZFb deletions are rare and the associated phenotype has to be delimited. This work shows the interest of real-time PCR [polymerase chain reaction] technique to detect partial deletions or duplications of the AZFc region. The results are discussed following available data regarding mapping and molecular pathology of the Y chromosome
