RESUMEN

Oftentimes ignored or infrequently expressed, some transgender persons harbor a desire for parenthood. Given the evolution of medical techniques and the enacting of legislative reforms, it is henceforth possible to propose fertility preservation strategies in the overall context of gender transidentity. During the "female to male" (FtM) transition pathway, androgen therapy has an impact on gonadic function, generally inducing blockage of the ovarian function, with amenorrhea. Even though these events may be reversed on cessation of treatment, the possible long-term effects on future fertility and on the health of children yet to be born are little known. Moreover, transition surgeries definitively compromise the possibility of pregnancy insofar as they involve bilateral adnexectomy and/or hysterectomy. Options for fertility preservation in the framework of FtM transition are premised on cryopreservation of oocytes and/or ovarian tissue. In a comparable manner, even though relevant documentation is lacking, hormonal treatments for persons transitioning from male to female (MtF) can have an impact on future fertility. In the event of surgery involving bilateral orchidectomy in which spermatozoid cryopreservation has not been carried out, fertility is definitively impossible. In both cases and under present-day legislation, numerous legal and regulatory barriers render highly problematic the reutilization of cryopreserved gametes. Given these different constraints, it is indispensable to closely supervise these types of treatment by proposing psychological support.

RESUMEN

INTRODUCTION: Fertility preservation is essential before cancer treatment. When ejaculated sperm preservation is not possible, testicular tissue can be surgically collected by Onco-TESE technic (Oncological Testicular Sperm Extraction) to isolate sperm. We report on our experience with Onco-TESE in testicular cancer patients at the Rouen University Hospital. MATERIAL AND METHOD: Retrospective study including all pubescent men, treated for testicular cancer, uni- or bilateral, before any carcinological therapy, who have undergone Onco-TESE at the Rouen University Hospital. Fragment weight, detection of sperm or its precursors were analysed. A histological interpretation of the testicular tumor was carried out. For each positive sample, straws were kept at the French Sperm Bank. RESULTS: Twenty-four patients had an Onco-TESE: 58.34% severe sperm alteration (SSA) and 41.36% sperm collection failure (SCF), between 1996 and 2019. The mean age was 26.6 (±5.29) years. The mean procedure and length of stay were 71minutes (±30.7) and 3.75 days (±2.83), respectively. The rate of positive testicular biopsies (TB) was 58.33% overall and 66,67% in the case of TB on tumour testis. One patient had a Clavian-Dindo III complication. The mean number of straws preserved per patient was 14.28 (±15.34) for 7.14% use. CONCLUSION: Our results seem to confirm that Onco-TESE is an effective solution for preserving fertility in men with testicular cancer in cases of SSA or SCF. LEVEL OF EVIDENCE: III.

RESUMEN

OBJECTIVES: To describe regional differences in the relative fertility of HIV-positive vs. HIV-negative women and changes as antiretroviral treatment (ART) is scaled up, to improve estimates of predicted need for and coverage of prevention of mother-to-child transmission services at national and subnational levels. METHODS: We analysed 49 nationally representative household surveys in sub-Saharan Africa between 2003 and 2016 to estimate fertility rate ratios of HIV-positive and HIV-negative women by age using exponential regression and test for regional and urban/rural differences. We estimated the association between national ART coverage and the relationship between HIV and fertility. RESULTS: Significant regional differences exist in HIV and fertility relationships, with less HIV-associated subfertility in Southern Africa. Age patterns of relative fertility are similar. HIV impact on fertility is weaker in urban than rural areas. For women below age 30, regional and urban/rural differences are largely explained by differences in age at sexual debut. Higher levels of national ART coverage were associated with slight attenuation of the relationship between HIV and fertility. CONCLUSIONS: Regional differences in HIV-associated subfertility and urban-rural differences in age patterns of relative fertility should be accounted for when predicting need for and coverage of PMTCT services at national and subnational level. Although HIV impacts on fertility are somewhat reduced at higher levels of national ART coverage, differences in fertility between HIV positive and negative remain, and fertility of women on ART should not be assumed to be the same as HIV-negative women. There were few data in recent years, when ART has reached high levels, and this relationship should continue to be assessed as further evidence becomes available.

RESUMEN

OBJECTIVE: Understanding the fertility of HIV-positive women is critical to estimating HIV epidemic trends from surveillance data and to planning resource needs and coverage of prevention of mother-to-child transmission services in sub-Saharan Africa. In the light of the considerable scale-up in antiretroviral therapy (ART) coverage over the last decade, we conducted a systematic review of the impact of ART on the fertility outcomes of HIV-positive women. METHODS: We searched Medline, Embase, Popline, PubMed and African Index Medicus. Studies were included if they were conducted in sub-Saharan Africa and provided estimates of fertility outcomes (live births or pregnancies) among women on ART relative to a comparison group. RESULTS: Of 2070 unique references, 18 published papers met all eligibility criteria. Comparisons fell into four categories: fertility of HIV-positive women relative to HIV-negative women; fertility of HIV-positive women on ART compared to those not yet on ART; fertility differences by duration on ART; and temporal trends in fertility among HIV-positive women. Evidence indicates that fertility increases after approximately the first year on ART and that while the fertility deficit of HIV-positive women is shrinking, their fertility remains below that of HIV-negative women. These findings, however, were based on limited data mostly during the period 2005-2010 when ART scaled up. CONCLUSIONS: Existing data are insufficient to characterise how ART has affected the fertility of HIV-positive women in sub-Saharan Africa. Improving evidence about fertility among women on ART is an urgent priority for planning HIV resource needs and understanding HIV epidemic trends. Alternative data sources such as antenatal clinic data, general population cohorts and population-based surveys can be harnessed to understand the issue.

RESUMEN

AIMS: To describe sexuality and fertility alterations secondary to chronic kidney disease and their outcomes after renal transplantation. MATERIAL AND METHODS: An exhaustive systematic review of the scientific literature was performed in the Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of the following keywords: erectile dysfunction; impotence; sexuality; pregnancy; fertility; renal transplantation. Publications obtained were selected based on methodology, language, date of publication (last 10 years) and relevance. Prospective and retrospective studies, in English or French, review articles; meta-analysis and guidelines were selected and analyzed. This search found 706 articles. After reading titles and abstracts, 76 were included in the text, based on their relevance. RESULTS: The observed prevalence of erectile dysfunction is high in men with chronic kidney disease. The causes of erectile dysfunction are numbers and its origin is often multifactorial. Most of the time, kidney transplantation improves sexuality and the management of erectile dysfunction in transplanted men is similar to the general population. Improvement in sexuality in men and women after kidney transplantation may conduct to pregnancy. The outcomes of pregnancy after transplantation are quite good in absence of risk factors such as time to pregnancy less than 1 year after transplantation, uncontrolled high blood pressure, and decreased renal function of the graft. Adaptation of immunosuppression may be required to avoid any teratogenicity for the fetus. CONCLUSION: Kidney transplantation improves sexuality and fertility in men and women with chronic kidney disease.

RESUMEN

AIM: The aim of this work is to know the fertility rate of the metacestodes resulting from patients suffering from hydatidosis, the one of protoscoleces's viability and by comparing the results obtained with those found elsewhere. It reports, also, the epidemiological, clinical and diagnostically aspects of the studied patients. MATERIALS AND METHODS: This study has carried on 78 hydatics samples resulting from 78 patients collected between 2005 and 2012 at the laboratory of parasitology of the Mustapha hospital center of Algiers. A questionnaire on the epidemiological context (contact with an animal-host of the cycle, place of residence, presence of family cases reached of hydatidosis and knowledge on the hydatic disease) concerned 69 patients. For each sample, a direct microscopic examination is made with or without vital staining. The presence of protoscoleces made qualified the fertile cyst. Those visualized moving or resistant to eosin at 0.2% are considered viables. Indirect diagnosis is based on the techniques: passive hemagglutination, electrophoresis, Elisa IgG Echinococcus granulosus and immunoblotting IgG "Echinococcus". Molecular analysis is based on PCR and sequencing the partials fragments of two mitochondrial genes with the primers COX1 and ND1. RESULTS: The results obtained show that the surgical frequency of hydatidosis is significant at the young adult and at the child. The epidemiological context associated at the disease is the conjointly presence of a dog and herbivores. The fertility rate of human hydatid cysts is 88.4% and the ones of viability of the protoscoleces is 74.5%. In this series, the serology shows global positivity at 70%. The molecular characterization of five samples identify the species: E. granulosus ss. CONCLUSION: Finally, the viability and fertility rates found here are raised. Sometimes viables protoscoleses are found after use of scolicidal solution. In front of these results, the parasitical treatment is more than necessary in order to minimize the risk of occurred of secondary echinococcosis or the relapses postoperatives.

RESUMEN

OBJECTIVE: The French Law relating to Bioethics allows access to medically assisted reproduction for lesbian couples and single women and has expanded the possibilities for self-preservation of gametes. The question now arises of new uses of gametes of the couple, within couples of two cis women, one cis woman and one transgender woman, or two transgender individuals. The acronym EUGIC (Extension of the Use of Gametes in IntraCouple) allows these new situations to be grouped together, particularly if gametes have already been previously cryopreserved, thus avoiding the need for gamete donation. METHODS: Analysis of the different situations of sperm use from a trans woman using gametes available within the couple rather than gamete donation. RESULTS: The inconsistency in the use of sperm from a trans woman, the situations already encountered by professionals, the prospects for filiation for a trans woman as well as the issues related to the interest of the unborn child are discussed. CONCLUSION: French law does not fully address the use of a trans woman's spermatozoa to meet the new EUGIC requirements and leads to complex situations for healthcare professionals.

RESUMEN

Conditioning regimen prior to hematopoietic stem cell transplantation have an impact on patient fertility through the use of gonadal irradiation and/or bifunctional alkylating agents. Their impact on fertility depends mainly on the dose used and, in women, on age at the time of treatment. All patients should benefit before treatment from a consultation informing them of the potential impact on fertility and of fertility preservation techniques. In the absence of contraindications, the major toxicity of myeloablative conditioning regimen justifies fertility preservation. There are few data concerning fertility after reduced-intensity conditioning. Despite lower theoretical gonadotoxicity, we also recommend fertility preservation, if possible before transplantation. The fertility preservation techniques used depend on the patient's age, pathology and conditioning. In the event of subsequent use of harvested gonadal tissue in the context of acute leukemia or aggressive lymphoma, it is advisable to assess the risk of reintroduction of tumor cells. Finally, it is recommended to assess gonadal function after transplant, especially after reduced conditioning. If there is persistent residual gonadal function, post-treatment fertility preservation should be discuss.

RESUMEN

INTRODUCTION: In France, the breast cancer is the most common cancer among women under the age of 40. From 38 to 70% of women have not fulfilled their parental plans at the time of diagnosis. The gonadotoxicity of the treatments and the follicular physiological decline linked to age can become an obstacle to this project. METHODS: Among the patients, 386 were treated for breast cancer at the Centre Georges-François-Leclerc in Dijon between January 2011 and December 2018 were identified. 192 patients aged under 39 met the inclusion criteria. We excluded metastatic cancers, cancer in situ and pregnant patients at diagnosis. A total of 124 patients agreed to participate in the study. The included patients filled out a self-questionnaire. Data were collected from the patient's electronic medical. The primary endpoint of this study was the live birth rate. RESULT: Among women who desired a child after breast cancer, the overall rate of live births was 36.2 % (21/58). Most achieved pregnancies were spontaneous (90.5 %). No factor was significantly associated with the absence of obtaining birth. Fertility was preserved by oocyte cryopreservation in 13.8 % of patients (17/124). The median time to conception in patients who received chemotherapy was 8 months [1.0-60.0] vs 2 months [1.0-7.0] in women who did not receive chemotherapy. DISCUSSION: The non-negligible proportion of live births following spontaneous pregnancy after breast cancer allows us to be reassuring for patients. However, the emergence of new chemotherapy protocols whose consequences on long-term gonadotoxicity are still not well known requires further studies and prompts the promotion of fertility preservation as a precautionary measure.

RESUMEN

In preparation for a new version of the CRAT (Centre de référence sur les agents tératogènes) website, an evaluation of user satisfaction was carried out. An invitation to complete an online questionnaire covering the various dimensions of the website (appearance, content, interactivity, ease of use, technical performance) was sent in April 2022 to healthcare professionals who referred to CRAT for clinical expertise over the previous two years. After sending out 3224 individual e-mail invitations, 758 evaluators completed the questionnaire in full (response rate: 23.5%). The evaluation revealed a high-level of overall satisfaction among site users (98.0% very satisfied or satisfied). Satisfaction with the site's appearance was also high, although comments were made about the site's lack of a modern web design. Health professionals recognized in their responses the reliable, relevant and up-to-date nature of the content of this free, public online resource, independent of the pharmaceutical industry. On the basis of these highly favorable assessments, with content that has been widely acclaimed and areas for improvement that have caught the attention of site users (evolution of its appearance, of the search tool, implementation of a mobile site), a new version of www.lecrat.fr was launched in the fall of 2023.

RESUMEN

The Centre de Référence sur les Agents Tératogènes (CRAT) is a unique French national reference center involved in the risk assessment of exogenous agents (mainly drugs, but also medical imaging and addictions) on pregnancy, breastfeeding and fertility. To help improve patient care, CRAT makes its expertise available to healthcare professionals via its website (www.lecrat.fr), a free, independent and public online resource regularly updated by its multidisciplinary team. In December 2023, a new version was launched, based on the evolutions desired by the CRAT team and on a satisfaction survey of website's users. A predictive search bar integrated into the home page now enables users to find the specific information they are looking for more quickly. To optimize the access via smartphones, a mobile version is now available.

RESUMEN

INTRODUCTION: Five cases of ovarian tumors (granulosa cell tumors) in cattle are presented from the patient load of the Vetsuisse University of Zurich and Bern. The aim of this work was to demonstrate the variable development of the illness and to indicate diagnostic and therapeutic possibilities to the practicing veterinarians. Case 1 shows bilateral appearance and the development of malignancy and metastases. The main symptoms in case 2 were the development of the mammary gland in a juvenile animal and the behavior modification due to a hormonal imbalance. The cases 3, 4 and 5 underwent surgery, case 4 restarted reproductive activity resulting in five subsequent pregnancies. The initial presumption is a result of a gynecological including ultrasonographic examination and can be verified by the analysis of Müllerian Inhibiting Hormone in serum. The decision to perform surgery should be done rapidly, as normal fertility can be achieved if the tumor is located unilaterally. Tumor growth and potential malignancy can provoke fatal health issues and also make it impossible to use meat of these animals for consumption.


INTRODUCTION: Cinq cas de tumeurs ovariennes (tumeurs des cellules de la granulosa) chez les bovins sont présentés à partir de la patientèle de l'Université Vetsuisse de Zurich et de Berne. Le but de ce travail était de montrer l'évolution variable de la maladie et d'indiquer les possibilités diagnostiques et thérapeutiques aux vétérinaires praticiens. Le cas 1 montre la possibilité d'une apparition bilatérale avec développement d'une tumeur maligne et de métastases. Les principaux symptômes du cas 2 étaient le développement de la glande mammaire chez un animal juvénile et la modification du comportement due à un déséquilibre hormonal. Les cas 3, 4 et 5 ont subi une intervention chirurgicale, le cas 4 a repris une activité de reproduction avec cinq gestations ultérieures. La présomption initiale résulte d'un examen gynécologique et peut être vérifiée par l'analyse de l'hormone anti-müllérienne dans le sérum. La décision d'opérer doit être prise rapidement, car une intervention chirurgicale pour enlever l'ovaire atteint peut, dans l'idéal, permettre une reprise de l'activité de reproduction. La croissance de la tumeur et la malignité potentielle peuvent provoquer des problèmes de santé fatals et rendre la viande de ces animaux impropre à la consommation.

RESUMEN

In the attempt to harmonize clinical practices between different French transplantation centers, the French Society of Bone Marrow Transplantation and Cell Therapy (SFGM-TC) set up the third annual series of workshops which brought together practitioners from all member centers and took place in October 2012 in Lille. Here we report our results and recommendations regarding the management of short and long-term endocrine dysfunction following allogeneic stem cell transplantation. The key aim of this workshop was to give an overview gonadal failure, fertility preservation and post-transplant.

RESUMEN

While electronic cigarettes have been on the rise in France for the past ten years, data on their prevalence, use patterns and safety have remained fragmented and controversial. Electronic cigarettes seem to not be a harmless product to use, because although they contain fewer harmful substances than traditional cigarettes, they still contain toxic products such as endocrine disruptors, which appear to have a negative impact on hormonal homeostasis, morphology and functioning of the animal reproductive system. Mostly presented as a harmless alternative to traditional cigarettes by industry lobbies, electronic cigarettes are often offered as an aid to smoking cessation in the same way as nicotinic substitutes. This strategy is especially proposed without knowledge of its effects on human reproductive health. Indeed, there are currently very few scientific publications, which study the impact of the use of electronic cigarettes, nicotine and the vapours it delivers on fertility and the functioning of the human female and male reproductive systems. Thus, the great majority of the data we have to date come from studies carried out in animal populations and show that electronic cigarettes exposure affect fertility. There is, to our knowledge, no scientific publication on the results in Assisted Reproductive Technology in case of use of electronic cigarettes, motivating the realization of the study IVF-VAP currently underway in the department of Medicine and Biology of Reproduction of the Amiens Picardie University Hospital.

RESUMEN

When to Stop Contraception - Reasons and Consequences of Delaying Parenthood Abstract. Women are delaying motherhood for many reasons. However, knowledge on age-related decline of fertility is limited. Many patients and even physicians are not aware that female fertility starts to diminish significantly after the age of thirty-two years, and success rates of in vitro treatment are overestimated in the general population. Apart from maternal age there is no predictor for future fecundity. Physicians should actively discuss reasons for delaying motherhood and options for improving fecundity. During the reproductive life span, women need reliable counselling on contraception and fertility.

RESUMEN

Chemotherapy to treat cancer is usually responsible for early ovarian follicle depletion. Ovarian damage induced by cancer treatments frequently results in infertility in surviving patients of childbearing age. Several fertility preservation techniques have been developed. Nowadays, oocyte or embryo cryopreservation with or without ovarian stimulation and cryopreservation of the ovarian cortex are the most commonly used. However, these methods may be difficult to implement in some situations, and subsequent use of the cryopreserved germ cells remains uncertain, with no guarantee of pregnancy. Improved knowledge of the molecular mechanisms and signaling pathways involved in chemotherapy-induced ovarian damage is therefore necessary, to develop new strategies for fertility preservation. The effects of various chemotherapies have been studied in animal models or in vitro on ovarian cultures, suggesting various mechanisms of gonadotoxicity. Today the challenge is to develop molecules and techniques to limit the negative impact of chemotherapy on the ovaries, using experimental models, especially in animals. In this review, the various theories concerning ovarian damage induced by chemotherapy will be reviewed and emerging approaches for ovarian protection will be explained.

RESUMEN

The current pandemic context raises questions about COVID-19 consequences on Assisted Reproduction Technology (ART). Indeed, according to the first Biomedicine Agency recommendations, ART centers suspended their activities in March 2020 during the first wave of Covid-19. However, SARS-CoV-2 direct and indirect effects on gametes, fertility, pregnancy and neonatal health are still debated. The aim of this review is to assess the available data on this subject, to inform patients in care and adapt daily practice. Most recent studies are based on the effects of the infectious syndrome, on hormonal factors as well as on the expression of viral entry proteins (ACE2 and TMPRSS2) in cells involved in gametogenesis, to assess the impact of COVID-19. So far, no effect on female gametes was highlighted. More studies are needed to confirm this hypothesis. Mother to children transmission couldn't be proven, yet neonatal infection remains possible. However, men are more susceptible to be infected by SARS-CoV-2, to be symptomatic, and spermatogenesis is likely to be affected. Presence of the virus in semen is infrequently reported, but all of these parameters should be taken into account in ART.

RESUMEN

OBJECTIVES: The strategy of fertility preservation (FP) in cervical cancer has been challenged for several years and a therapeutic de-escalation seems to be necessary. In this context, we evaluated the oncological, fertility and obstetric outcomes of surgical techniques performed in our centre for FP. METHODS: This retrospective uni centric trial included 75 patients, managed at the Gustave Roussy Institute between 1995 and 2020, for cervical cancer (stage IB1 FIGO 2018) and having conducted a fertility preservation project after a complete pre-therapy work-up. The objective of this study was to understand our results on fertility and obstetrical outcomes and to correlate them with oncological data and finally to evaluate the evolution of our surgical practices. RESULTS: 54 patients benefited from an extended trachelectomy and no lymph node involvement was found. 1 patient received a complementary treatment postoperatively which did not allow to preserve her fertility. The recurrence rate was 4.8% (4/75) with one death described. 31 pregnancies were obtained, representing a pregnancy rate of 50%. 74% of pregnancies were obtained spontaneously and 60% of pregnancies were carried to term. CONCLUSION: Our results are similar to those in the literature. Despite a fertility preservation project, only half of the patients were able to achieve a pregnancy.
