BACKGROUND: Chlamydia, caused by the bacterium Chlamydia trachomatis(C. trachomatis), is the most common sexually transmitted disease. The incidence is not clear due to the asymptomatic nature of early stage of infections. The incidence of Chlamydia has not been fully investigated in the Chinese Han population. Since chronic infection with can C. trachomatis can lead to infertility in males and females, it is important to determine the impact of infection on clinical outcomes. The aim of this study is to explore the epidemiology of C...

STUDY QUESTION: Are infertile women who screen positive for depression less likely to initiate infertility treatments? SUMMARY ANSWER: Infertile women who screen positive for depression are less likely to initiate treatment for infertility. WHAT IS ALREADY KNOWN: Infertility imposes a psychological burden on many couples. Depression and anxiety have been demonstrated in ~40% of infertile women, which is twice that of fertile women. Further, the psychological burden associated with infertility treatment has been cited as a major factor for discontinuation of infertility care...

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women during reproductive ages. Clinical symptoms associated with PCOS, such as hirsutism, acne, alopecia, obesity, and infertility, may lead to emotional morbidity and then impaired sexual function in those affected. During intrauterine development, the fetus may program the development of diseases during adulthood. In this study, we aimed to examine sexual function in women with PCOS, exposed to maternal androgen excess during their prenatal life compared to non-exposed PCOS patients...

The target gene of rapamycin (TOR) is conserved from invertebrates to vertebrates, and plays critical roles in cell growth, nutrient sensing, lifespan and reproduction. In this paper, we employed RNA interference (RNAi) to study the function of TOR in male brown planthoppers (BPH), Nilaparvata lugens. Here we discovered that no offspring was produced when wildtype females BPH mated with NlTOR RNAi males. To understand the influence of NlTOR on male BPH infertility, we dissected the reproductive system of a NlTOR RNAi male, and found that the testes were normal and the seminal vesicles were full of sperm, while the accessory gland was poorly developed after knocking down NlTOR expression...

We investigated the prevalence of smoking and factors associated with smoking in infertile Korean women. Smoking status, education, occupation, personal habits, past medical history, current illness, stress level, and menstrual characteristics were collected from self-report questionnaires. The Beck Depression Inventory (BDI) was used to assess the degree of depression. Data on the causes of infertility and levels of six reproductive hormones were collected from medical records. Among 785 women less than 42 years of age, the prevalence of current, secondhand, past, and never smokers were 12...

Ultrasonography is a powerful tool to non-invasively monitor in real time the development of the human fetus in utero. Although genetically engineered mice have served as valuable in vivo models to study both embryo implantation and pregnancy progression, such studies usually require sacrifice of parous mice for subsequent phenotypic analysis. To address this issue, we used three-dimensional (3-D) reconstruction in silico of high-frequency ultrasound (HFUS) imaging data for early detection and characterization of murine embryo implantation sites and their development in utero...

Indirect inguinal hernia is one of the most common congenital anomalies in children, with a reported prevalence of 0.8-4.4%.1 About 15-20% of hernias in female infants contain ovary, and in rare cases a fallopian tube.2 However, only a few cases contain the uterus and both ovaries in the hernia sac.3 The normal anatomy is altered when an ovary is trapped in a hernia sac, and these changes make torsion more likely and increase the risk of infertility. Although an irreducible ovary is not at great risk of compression of its blood supply, in these occurrences, ovarian torsions have been reported in 2%-33%, emphasizing the importance of early surgical repair in irreducible hernias, even in asymptomatic patients...

Elevated estradiol levels are correlated with male infertility. Causes of hyperestrogenism include diseases of the adrenal cortex, testis or medications affecting the hypothalamus-pituitary-gonadal axis. The aim of our study was to elucidate the effects of estradiol treatment on testicular cellular morphology and function, with reference to the treatment regimen received. Testes samples (n = 9) were obtained post-orchiectomy from male-to-female transsexuals within the age range of 26-52 years. Each patient had a minimum of 1-6 years estradiol treatment...

OBJECTIVE: Infertility is a disease of the reproductive system defined by inability to conceive after having regular unprotected intercourse. Both environmental and genetic factors can be involved in female infertility. Manganese superoxide dismutase (MnSOD) is a crucial mitochondrial antioxidant enzyme that has a key role in cellular defense against agents that induce oxidative stress. The present study was aimed to evaluate the MnSOD A16V gene polymorphism in female infertility in northern Iran...

Androgen insensitivity syndrome is a rare disorder of sex development and its clinical manifestations vary from subtle male infertility to an overt complete androgen insensitivity syndrome (CAIS) with a female phenotype. CAIS is often diagnosed at puberty or in adolescence during investigation for primary amenorrhoea. Undiagnosed patients have an increased risk of development of malignancy in the harboured testes. Inguinal hernia is the commonest mode of presentation of CAIS in childhood and various screening methods are available during the initial herniorrhaphy procedure...

Osnat Hakimi, Luiz-Claudio Cameron
BACKGROUND: Infertility has been described as a devastating life crisis for couples, and has a particularly severe effect on women, in terms of anxiety and depression. Anovulation accounts for around 30% of female infertility, and while lifestyle factors such as physical activity are known to be important, the relationship between exercise and ovulation is multi-factorial and complex, and to date there are no clear recommendations concerning exercise regimes. OBJECTIVES: The objective of this review was to systematically assess the effect of physical activity on ovulation and to discuss the possible mechanisms by which exercise acts to modulate ovulation in reproductive-age women...

Bioengineering strategies have demonstrated enormous potential to treat female infertility as a result of chemotherapy, uterine injuries, fallopian tube occlusion, massive intrauterine adhesions, congenital uterine malformations and hysterectomy. These strategies can be classified into two broad categories: 1) Transplantation of fresh or cryopreserved organs into the host; and 2) tissue engineering approaches that utilize a combination of cells, growth factors and biomaterials that leverages the body's inherent ability to regenerate/repair reproductive organs...

Steroidogenic factor 1 (NR5A1, SF-1, Ad4BP) is a transcriptional regulator of genes involved in adrenal and gonadal development and function. Mutations in NR5A1 have been among the most frequently identified genetic causes of gonadal development disorders and are associated with a wide phenotypic spectrum. In 46,XY individuals, NR5A1-related phenotypes may range from disorders of sex development (DSD) to oligo/azoospermia, and in 46,XX individuals, from 46,XX ovotesticular and testicular DSD to primary ovarian insufficiency (POI)...

SRY-mutation-caused sex reversal is a rare disease and mostly associated with a de novo mutation since the patients with defective SRY is infertile. There are many reports about SRY-mutation associated 46, XY ovarian disorder of sex development (DSD), but few described their molecular mechanism. Here we report a de novo mutation 224G>T (R75M) in SRY associated with a phenotypic female, 46, XY karyotype and dysgerminoma. The wild and mutated SRY were cloned into recombinant plasmid and expressed in cells in vitro, the result showed the mutated SRY is greatly accumulated in cytoplasm while the wild type SRY is mostly localized in nucleus...

Germline ablation of VGF, a secreted neuronal, neuroendocrine, and endocrine peptide precursor, results in lean, hypermetabolic, and infertile adult mice that are resistant to diet-, lesion-, and genetically-induced obesity and diabetes (Hahm et al., 1999, 2002). To assess whether this phenotype is predominantly driven by reduced VGF expression in developing and/or adult neurons, or in peripheral endocrine and neuroendocrine tissues, we generated and analyzed conditional VGF knockout mice, obtained by mating loxP-flanked (floxed) Vgf mice with either pan-neuronal Synapsin-Cre- or forebrain alpha-CaMKII-Cre-recombinase-expressing transgenic mice...
