Study: Glyphosate damages reproductive development in rats, increasing risk for cancer and infertility

(NaturalNews) Glyphosate -- the active ingredient of Monsanto's blockbuster herbicide Roundup -- may disrupt development of the uterus, leading to fertility problems and cancer, according to a study conducted by researchers from Argentina and published in the journal Toxicology.Roundup...

We present a case series of 2 sisters in their 20s who presented with isolated uterine leiomyomas and were found to carry a novel mutation for the fumarate hydratase gene. One patient was referred for treatment of infertility and recurrent miscarriages and the other was referred for acute symptomatic anemia due to myomas. Prompt diagnosis of hereditary leiomyomatosis renal cell cancer was made due to a high index of clinical suspicion based on early onset disease and familial clustering as well as characteristic pathologic findings on uterine leiomyoma surgical specimen. Timely diagnosis not only allowed for genetic counse...

This exposure also causes altered gene expression in the female reproductive tract that persists into adulthood. To further explore on a genome-wide basis how neonatal estrogen exposure results in permanent epigenetic changes, we performed RNA-seq and ChIP-seq analyses of DES-treated and contro...

Abstract Forkhead box A2 (FOXA2) is a pioneer transcription factor involved in organ development, function and cancer. In the uterus, FOXA2 is essential for pregnancy and expressed specifically in the glands of the endometrium loss of FOXA2 function occurs during development of endometrial cancer in humans. The present study describes the development of a mouse model for conditional expression of mouse FOXA2. Using a system consisting of a minigene located at the Rosa26 locus, a CAG-S-mFOXA2 allele was generated in embryonic stem cells and subsequently in mice; before activation, the minigene is silent due to a fl...

A second woman in the U.S. born without a uterus has given birth to a baby, thanks to a uterus transplant. The birth took place at Baylor University Medical Center at Dallas, a part of Baylor Scott &White, which performed the first birth via uterus transplant late last year. The baby, born in February, is a girl. The hospital is not revealing the identity of the mother, but says the pregnancy and birth were uncomplicated. The birth is the second in the hospital’s ongoing uterus transplant clinical trial. The women in the trial have absolute uterine factor infertility (AUI), which means their uterus is nonfunction...

AbstractAdult survivors of childhood cancers are more prone to developing poor reproductive and obstetrical outcomes than their siblings and the general population as a result of previous exposure to chemotherapy and radiation during childhood. Chemotherapy drugs exert cytotoxic effects systemically and therefore can damage the ovaries, leading to infertility, premature ovarian failure, and, to a lesser extent, spontaneous abortions. They have very limited or no deleterious effects on the uterus that can be recognized clinically. By contrast, radiation is detrimental to both the ovaries and the uterus, thereby causing a gr...

Abstract Endometriosis is a common and challenging condition of reproductive-aged women that carries a high individual and societal cost. The many molecular dissimilarities between endometriosis lesions and eutopic endometrium create difficulties in the development of new drug therapies and treatments. Surgery remains the gold standard for definitive diagnosis, but it must be weighed against the risks of surgical morbidity and potential decreases in ovarian reserve, especially in the case of endometriomas. Safe and effective surgical techniques are discussed within this article for various presentations of endomet...

AbstractSTUDY QUESTIONAre the large cells derived from cultured DEAD box polypeptide 4 (DDX4)-positive oogonial stem cells (OSCs), isolated from the ovarian cortex of non-menopausal and menopausal women, oocyte-like cells?SUMMARY ANSWERUnder appropriate culture conditions, DDX4-positive OSCs from non-menopausal and menopausal women differentiate into large haploid oocyte-like cells expressing the major oocyte markers growth differentiation factor 9(GDF-9) and synaptonemal complex protein 3 (SYCP3) and then enter meiosis.WHAT IS KNOWN ALREADYThe recent reports of OSCs in the ovaries of non-menopausal and menopausal women su...

Polycystic ovarian disease ( PCOD) is a common cause of infertility. Typically, most of these patients have irregular cycles because they don't ovulate regularly. Now, because they don't ovulate, they don't get pregnant , and they don't get regular periods either . This is because they produce a lot of estrogen, but there's no progesterone production at all, because of the lack of ovulation.Now, this means that every time they miss a period, they're very hopeful that this time they could be pregnant. They wait and they wait, and after two months or three months they don't get a period, they finally go to a doctor who does ...

CONCLUSIONS: Women with PCOS display a dysregulation of the Hypothalamic-Pituitary-Ovarian axis, which alters the steroid pathway. In addition, the deficiency in the withdrawal of estrogen and progesterone in the endometrium results in abnormal endometrial cellular proliferation. The imbalance in adipose tissue observed in PCOS patients reinforces the increases in circulating hormones. The present review describes the role of hormones, metabolites, cytokines, adhesion molecules and the insulin/glucose pathway related to the uterine endometrium in women with PCOS and their role in implantation failure and development of end...

We acknowledge the ongoing concerns of women with endometriosis, a chronic gynaecological condition affecting about 176 million women worldwide, regarding information about their increased ovarian cancer risk. Endometriosis is an inflammatory disease process characterised by lesions of endometrial-like tissue outside the uterus —commonly on the pelvic peritoneum and ovaries—that is associated with debilitating pelvic pain and infertility.1 Although benign, endometriosis has cancer-like features,2 a mutation profile similar to that of ovarian cancer,3 and an increased ovarian cancer risk.
