乳杆菌是维持女性阴道环境的重要菌群。惰性乳杆菌是发现最晚、基因组最小的一种乳杆菌,也是健康女性阴道内众多乳杆菌中的一种。惰性乳杆菌表现出的特性与以往认识的乳杆菌不同,其存在往往与阴道微生态紊乱有关。由于常能在细菌性阴道病(bacterial vaginosis,BV)或BV中间型患者阴道中检测到该菌,因此有研究认为惰性乳杆菌通过某种机制促进阴道内致病菌的定植和侵袭,从而间接参与BV的发病。以惰性乳杆菌为优势菌的阴道环境明显比以卷曲乳杆菌为优势菌的阴道环境更容易定植假丝酵母。复发性外阴阴道假丝酵母菌病(vulvovaginal candidiasis,VVC)患者阴道菌群丰富度明显降低,并以惰性乳杆菌为优势菌,而卷曲乳杆菌含量明显减少。惰性乳杆菌在HIV感染、HPV感染及沙眼衣原体感染女性的阴道中具有较高的定植率,有研究表明其存在率也与宫颈上皮内瘤变有关。  相似文献

1 Correspondence address. E-mail: akandewole{at}yahoo.com Infertility in developing countries is pervasive and a seriousconcern. In addition to the personal grief and suffering itcauses, the inability to have children especially in poor communitiescan create broader problems, particularly for the woman. Infertilityservices in developing countries span the spectrum from preventionto treatment. From a societal and public health standpoint,prevention is cost–effective and is considered by manygovernments and public health care providers to be a priorityfor service delivery. While prevention remains paramount, takenalone it ignores the plight of infertile couples, includingthose with non-infectious causes of infertility. Two key argumentsare frequently used to challenge the development of new reproductivetechnologies in developing countries: overpopulation and limitedresources. Evidence supports the conclusion that there is acompelling need for infertility treatment beyond prevention.In many instances, assisted reproductive technologies (ART)are the last hope or the only means to achieve a child for couples.In an effort to make much needed ART to developing countriesaccessible and affordable, developing countries should lookto public–private partnerships. Governments have a responsibilityto ensure safe and effective services including the controlof standards for clinical procedures and the regulation of professionalpractice.  相似文献

1 Correspondence address. E-mail: silke.dyer{at}uct.ac.za HIV infection and infertility are two common reproductive healthdisorders in Africa. From the perspective of infertility-relatedreproductive health care, the HIV epidemic has created severalchallenges which include reduction of fecundity, depletion ofscarce health resources, creation of barriers to infertilitytreatment and increased suffering. Infertility in turn is arisk factor for HIV acquisition and a possible force in thespread of the HIV epidemic. Recognition of the reproductivehealth needs and desires of HIV-infected infertile men and womenis a prerequisite for addressing these challenges. Subsequentstrategies comprise the development of treatment guidelinesfor low-resource environments and a greater integration of HIVand sexual and reproductive health services. Where resourcesfor infertility treatment are not available, the consequencesmust be critically assessed.  相似文献

In the Sunni Muslim world, religious mandates prohibit both adoption and gamete donation as solutions to infertility, including in the aftermath of in vitro fertilization (IVF) failures. However, both of these options are now available in two Middle Eastern countries with significant Shi'ite Muslim populations (Iran and Lebanon). On the basis of fieldwork in multisectarian Lebanon, I examine in this article attitudes toward both adoption and gamete donation among childless Muslim men who are undertaking IVF with their wives. No matter the religious sect, most Muslim men in Lebanon continue to resist both adoption and gamete donation, arguing that such a child "won't be my son". However, against all odds, some Muslim men are considering and undertaking these alternatives to family formation as ways to preserve their loving marriages, satisfy their fatherhood desires, and challenge religious dictates, which they view as out of step with new developments in science and technology. Thus, in this article I examine the complicated intersections of religion, technology, marriage, and parenthood in a part of the world that is both poorly understood and negatively stereotyped, particularly in the aftermath of September 11, 2001.  相似文献

近年来研究显示,kisspeptin在大脑的性别分化、性激素正负反馈调节、青春期始动以及机体能量信号转导等生理过程中起到重要作用,表明kisspeptin可能是女性生殖功能成熟及调控的一个关键性信号因子。除下丘脑分泌的kisspeptin之外,生殖器官局部表达的kisspeptin在机体正常生殖过程中的作用也不断得到证实。研究表明,很多生殖内分泌疾病,如单纯性促性腺激素分泌不足的性腺机能减退症(isolated hypogonadotropic hypogonadism, IHH)、多囊卵巢综合征(polycystic ovary syndrome, PCOS)、卵巢早衰(premature ovarian failure, POF)、病理性高泌乳素血症等,都与kisspeptin的异常表达有关。通过给予外源性kisspeptin可解决辅助生殖技术应用中的一些问题。本文主要就kisspeptin在女性生殖内分泌尤其是在辅助生殖领域研究中所取得的进展进行论述。  相似文献

Dioxins (eg, 2,3,7,8-tetrachlorodibenzo-p-dioxin/TCDD), as environmental endocrine disruptors and toxic carcinogens, can affect male reproductive health. The influence of dioxins is mediated via the aryl hydrocarbon receptor (AhR) pathway and its repressor (AhRR). In this study, we investigated the association of AhRR-c.565C>G transversion polymorphism with male infertility. In a hospital-based case-control study, 221 semen samples (111 infertile and 110 healthy controls) based on World Health Organization guidelines were collected from in vitro fertilization centers of Babol, Iran. The AhRR-c.565C>G (rs2292596) polymorphism was genotyped using a polymerase chain reaction-restriction fragment length polymorphism analysis. The difference in the allele frequency of AhRR-c.565C>G transversion polymorphism did not reach a significant level. The genotype frequency was statistically significantly different between fertile and infertile men. We found that polymorphism rs2292596 (Pro185Ala) was statistically s ignificantly associated with the risk of male infertility. In addition, the statistical difference became more significant when the frequency was compared between the Pro/Pro genotype and the Pro/Ala plus Ala/Ala genotype. The 185 Pro wild-type alleles of AhRR may be associated with the risk of male infertility. The proallele also may diminish inhibition of AhR-mediated signaling of exposure to environmental pollutants.  相似文献

The penises of bats are taxonomically distinctive in size and shape. In addition, they are variable in microscopic anatomy, indicating that histomorphological studies of copulatory organs of bats may help understanding their successful reproductive strategies. We studied adult males of 13 species of vespertilionid and phyllostomid bats. Both families exhibited the basic structure of the vascular penis of mammals: the hydrostatic elements of the corpora cavernosa and the corpus spongiosum surrounding the urethra, as well as accessory cavernous tissue. Variation in the position and amount of the tissues were observed in these families. Vespertilionid bats have a small glans penis with abundant accessory cavernous tissue on the prepuce and a highly variable baculum. The baculum varied in size and morphology, even among congeneric species, such as the three Lasiurus species and the two Myotis species. Phyllostomid species possess no bacula, but vascular structures are present to produce penile stiffening, particularly on the glans. Variation in the microscopic anatomy of the phyllostomid prepuce was observed, for example, Artibeus species had accessory cavernous tissue surrounded by a tunica albuginea, but Carollia perspicillata had two bundles of striated musculature and some adipose tissue; abundant pigments were present in the prepuce of most species.  相似文献

Direct development in amphibians is characterized by the loss of aquatic breeding. The anuran Adelophryne maranguapensis is one example of a species with direct development, and it is endemic to the state of Ceará, Brazil. Detailed morphological features of A. maranguapensis embryos and the stages of sequential development have not been described before. Here, we analyzed all available genetic sequence tags in A. maranguapensis (tyr exon 1, pomc and rag1) and compared them with sequences from other species of Adelophryne frogs. We describe the A. maranguapensis reproductive tract and embryonic body development, with a focus on the limbs, tail, ciliated cells of the skin, and the egg tooth, which were analyzed using scanning electron microscopy. Histological analyses revealed ovaries containing oocytes surrounded by follicular cells, displaying large nuclei with nucleoli inside. Early in development, the body is unpigmented, and the neural tube forms dorsally to the yolk vesicle, typical of a direct‐developing frog embryo. The hindlimbs develop earlier than the forelimbs. Ciliated cells are abundant during the early stages of skin development and are less common during later stages. The egg tooth appears in the later stages and develops as a keratinized microridge structure. The developmental profile of A. maranguapensis presented here will contribute to our understanding of the direct‐development model and may help preserve this endangered native Brazilian frog. genesis 54:257–271, 2016. © 2016 Wiley Periodicals, Inc.  相似文献
