Abortion caused by the parasite Neospora caninum is an important threat to the livestock industry worldwide. Trophoblasts and caruncular cells play major roles in initiating innate immune responses and controlling parasite infection at the fetal-maternal interface. In the present study, bovine uterine epithelial cells (BUECs) and bovine trophoblastic (BT) cells treated with bovine interferon-gamma (IFN-γ), IFN-alpha (IFN-α) and IFN-tau (IFN-τ) followed by infection with N. caninum were examined by measuring the mRNA expression levels of numerous pregnancy-associated proteins and observing parasite growth to elucidate the host-parasite interaction at the uteroplacental region...

BACKGROUND/OBJECTIVE: To report a case of adenomyosis in a woman with hyperprolactinemia which resolved after initiation of dopamine agonist therapy. CASE REPORT: A 35-year-old woman with a history of Graves' disease was referred for evaluation of hyperthyroidism in March 2020. She was started on methimazole and thyroid function normalized. The patient also had a history of a pituitary microadenoma and was previously treated with cabergoline which was stopped after 12 months as she became pregnant...

Placental development involves coordinated expansion and differentiation of trophoblast cell lineages possessing specialized functions. Among the differentiated trophoblast cell lineages are invasive trophoblast cells, which exit the placenta and invade into the uterus where they restructure the uterine parenchyma and facilitate remodeling of uterine spiral arteries. The rat exhibits deep intrauterine trophoblast cell invasion, a feature shared with human placentation, and is also amenable to gene manipulation using genome editing techniques...

Independently, both heat stress (HS) and zearalenone (ZEN) compromise female reproduction, thus the hypothesis that ZEN would affect phenotypic, endocrine, and metabolic parameters in pigs with a synergistic and/or additive impact of HS was investigated. Prepubertal gilts (n = 6-7) were assigned to: thermoneutral (TN) vehicle control (TC; n = 6); TN ZEN (40 μg/kg; TZ; n = 6); pair-fed (PF; n = 6) vehicle control (PC; n = 6); PF ZEN (40 μg/kg; PZ; n = 6); HS vehicle control (HC; n = 7); and HS ZEN (40 μg/kg; HZ; n = 7) and experienced either constant 21...

Brucellosis is a notorious zoonotic disease caused by Brucella , which can lead to reproductive diseases in humans and animals, such as infertility and abortion. Lipopolysaccharides (LPS) are the main virulence factor of Brucella . LPS derived from Brucella are different and non-classical and are less toxic and less active than LPS isolated from E. coli. However, the effects and possible mechanisms of Brucella LPS-caused pregnancy loss remain to be revealed. In the present study, we investigated the effects of Brucella suis S2 LPS on early pregnancy loss in mice...

Swyer syndrome-a rare syndrome associated with complete gonadal dysgenesis-is seen in phenotypically female patients with 46-XY karyotype. They usually present with primary amenorrhea or delayed puberty. The dysgenetic gonad, which is nonfunctional, is prone to undergo malignant transformation such as dysgerminoma, gonadoblastoma, etc. Timely diagnosis helps in deciding appropriate management strategies for the patient such as hormone replacement therapy and gonadectomy. Thirty-year-old patient with a female external phenotype presented to us with complaints of primary amenorrhea...

ETHNOPHARMACOLOGICAL RELEVANCE: Thespesia garckeana (F. Hoffm.) Exell & Hillc. is called Gorontula (Kola of Tula) in Nigeria, Morojwa in Bostwana, and Thespesia garckeana in South Africa and is widely distributed across Africa. Its parts reportedly possess multiple medicinal properties and are employed for treating various diseases. In Tula, Gombe State, Nigeria, the ripe fruit decoction is taken as remedy for female infertility as documented by Ochokwu and co in the Journal of Biology, Agriculture and Healthcare in 2015...

Estradiol (E2) and progesterone (P4) are essential sex steroid hormones that play critical roles in the pituitary gland and uterus. Recently, nesfatin-1, a polypeptide hormone that regulates appetite and energy homeostasis in the hypothalamus, was found to be expressed in the pituitary gland and uterus. In this study, we aimed to investigate the relationship between these two steroid hormones and the expression and function of nesfatin-1 in the pituitary gland and uterus using GH3 cells, a lacto-somatotroph cell line, and THESC cells, an endometrial stromal cell line...

IMPORTANCE: Recurrent pregnancy loss (RPL) is one of the most frustrating clinical entities in reproductive medicine requiring not only diagnostic investigation and therapeutic intervention, but also evaluation of the risk for recurrence. OBJECTIVE: The aim of this study was to review and compare the most recently published major guidelines on investigation and management of RPL. EVIDENCE ACQUISITION: A descriptive review of guidelines from the Royal College of Obstetricians and Gynaecologists, the European Society of Human Reproduction and Embryology, the American Society for Reproductive Medicine, the French College of Gynecologists and Obstetricians, and the German, Austrian, and Swiss Society of Gynecology and Obstetrics on RPL was carried out...

Endometriosis is characterized by the presence of endometrial glandular and stromal structures outside the uterine cavity. It is an inflammatory estrogen dependent disease characterized by gene polymorphisms. This is a very frequent pathology and represents one of the most important causes of infertility, as well as having an important level of morbidity in patients. Recently, an alteration of the processes of organogenesis of the uterus has been proposed as a pathogenetic mechanism of endometriosis. In this article we have compared the expression in deep endometriotic lesions and in normal endometrial tissue of some of the molecular factors known to be involved in the embryonic development of the uterine glands...

Macroadenoma is a tumor that typically develops in the epithelial cells of the pituitary gland. Patients suffering from the condition are often asymptomatic with complaints that are caused by hormonal imbalance. Therefore, chromosome analysis needs to be done to females aged >16 years presenting with amenorrhea. Karyotype 46,XY is a disorder of sex development (DSD) that is caused by the complex process of gene interactions, androgen synthesis, and hormone regulation. The patient initially came to the hospital for a scheduled transsphenoidal surgery due to pituitary macroadenoma, and later complained of primary amenorrhea and atypical external genital...

To evaluate the treatment efficacy of uterine artery embolization (UAE) using 8Spheres conformal microspheres for symptomatic uterine leiomyoma. In this prospective observational study, 15 patients were enrolled and underwent UAE by 2 experienced interventionalists from September 1, 2018, to September 1, 2019. All patients underwent menstrual bleeding scores, the symptom severity domain of the Uterine Fibroid Symptom and Quality of Life questionnaire scores (with lower scores indicating mild symptoms), pelvic contrast-enhanced magnetic resonance imaging, ovarian reserve tests (estradiol, prolactin, testosterone, follicle-stimulating, luteinizing, and progesterone), and other appropriate preoperative examinations within 1 week before UAE...

The "anthracycline, Epirubicin (EPI)," in managing breast cancer, is highly cytotoxic. Tryptophan-derived 3-indolepropionic acid (3-IPA) decreases oxidative damage, and its prospect of alleviating EPI-induced cytotoxicity was examined in rats' hypothalamus-ovary-uterus axis. Female rats: Control, EPI (2.5 mg/kg), 3-IPA alone (40 mg/kg), EPI+3-IPA (2.5 mg/kg + 20 mg/kg), EPI + 3-IPA2 (2.5 mg/kg + 40 mg/kg) were treated for 28 days. Subsequently, reproductive hormones, oxidative and inflammatory stress biomarkers, and tissue histology were examined...

Introduction: Endometriosis is defined by the presence of endometrial tissue outside the uterus, therefore leading to a chronic inflammatory reaction, adhesions development, scar tissue and a distorted pelvic female anatomy, most of the times leading to female infertility. Kisspeptin represents a neuropeptide thought to have an essential role in the reproductive functions of both female and male patients. Recently, positive correlations with kisspeptins were noticed in patients diagnosed with endometriosis...

Pueraria candollei var. mirifica (Fabaceae) root (PMR) has recently been developed as a potential selective estrogen receptor modulator (SERM) in menopausal women. Nowadays, many premenopausal women also take dietary PMR supplements, however, the exact biological effects of PMR have not been evaluated. This study included the application of the OECD guideline 407 for the assessment of 28-day oral exposure to PMR on pituitary-ovarian (PO) axis function and metabolic parameters in the premenopausal rat model...

BACKGROUND: The WHO recommends artemisinin-based combination regimens for uncomplicated Plasmodium falciparum malaria. One such combination is artemisinin-piperaquine tablets (ATQ). ATQ has outstanding advantages in anti-malarial, such as good efficacy, fewer side effects, easy promotion and application in deprived regions. However, the data about the reproductive and endocrine toxicity of ATQ remains insufficient. Thus, we assessed the potential effects of ATQ and its individual components artemisinin (ART) and piperaquine (PQ) on the reproductive and endocrine systems in Wistar rats...
