Throughout life, organisms are subjected to a variety of environmental perturbations, including temperature, nutrient conditions, and chemical agents. Exposure to external signals induces diverse changes in the physiological conditions of organisms. Genetically identical individuals exhibit highly phenotypic variations, which suggest that environmental variations among individuals can affect their phenotypes in a cumulative and inhomogeneous manner.

Follicular development is a highly coordinated process that in humans takes more than 6 months. Pituitary gonadotropins and a variety of locally produced growth factors and cytokines are involved in determining a precise sequence of changes in cell metabolism, proliferation, vascularization, and matrix remodeling in order to obtain a follicle with full ovulatory and steroidogenic capability. A low-grade inflammation can alter such processes leading to premature arrest of follicular growth and female reproductive failure. Read More

Approximately, 10-15% of women of reproductive age are affected by endometriosis, which often leads to infertility. Endometriosis often has an inherited component, and several causative predisposing factors are hypothesized to underlie the pathogenesis of endometriosis. One working hypothesis is the theory of retrograde menstruation. Read More

Corpus luteum (CL) produces progesterone (P) and 17-OH progesterone (17-OH P) during the luteal phase. Contrary to P, 17-OH P is not supplied as part of the luteal phase support following IVF-treatment. Therefore, measuring endogenous serum 17-OH P levels may more accurately reflect the CL function compared to monitoring serum P concentrations. Read More

Background: Little is known about the association between the anxiety toward the effects of radiation on reproduction caused by the Fukushima nuclear accident and the birth rate of people in Fukushima. Therefore, we examined changes and associated factors of future pregnancy intention among mothers in Fukushima Prefecture.

Knowledge about reproductive parameters in male harbour porpoises such as testicular histology and germ cell maturation as well as seasonal changes in spermatogenesis is scarce. Thus, the aim of the present study was to report changes in the histological appearance of the testicular morphology of neonatal and juvenile harbour porpoises during maturation, to identify stages of spermatogenesis in adult males and to detect seasonal modifications. The identification of these stages can be used to assess the developmental profile of gene expression during spermatogenesis and to identify defects in spermatogenesis arising in pathological conditions.

In Canada, payment for eggs is prohibited by law; however, what is considered payment is contentious and has yet to be defined.

Background: Discovering the association between genetic variations of metabolizing enzymes with idiopathic diseases such as ulcerative colitis (UC) may not only be an auxiliary agent in diagnosis but also could be an effective pharmacotherapy for inflammatory bowel disease (IBD). The aim of the present case-control study was to determine the association of cytochrome P450 2D6 (CYP2D6 *4), N-acteyltransferase-2 (NAT2*7) and multidrug resistance 1 (MDR1) 3435 C/T genotypes with UC susceptibility and thiopurine methyltransferase (TPMT) enzyme activity.
Methods: TPMT activity was measured by high performance liquid chromatography (HPLC) and genotypes for the 3 mentioned polymorphisms were determined in 215 unrelated UC patients and 212 unrelated healthy controls by polymerase chain reactionrestriction fragment length polymorphism (PCR-RFLP) in a Kurdish population from Iran.

Background: While traditional approaches focus on negative sexual experiences and sexual dysfunctions, within the positive psychology framework positive sexuality is a subjective experience of happiness and fulfillment with one's sexual expression, which contributes to well-being. No measure exists that specifically measures adult female positive sexuality and can be confidently used with women of any fertility/childlessness status. Read More

Uterine gland development, also known as adenogenesis, is a key uterine morphogenic process indispensable for normal uterine function and fertility. Our earlier studies have reported that overactivation of TGFB receptor 1 (TGFBR1) in the mouse uterus using progesterone receptor (Pgr)-Cre recombinase causes female infertility, defective decidualization, and reduced uterine gland formation, a developmental milestone of postnatal uterus. To understand mechanisms that underpin the disrupted uterine gland formation in mice with sustained activation of TGFBR1, we raised the question of whether early postnatal adenogenesis was compromised in these mice.

In recent years, the prevalence of infertility has increased due to delayed child bearing and increase in the rate of male infertility. Given the high cost of fertility treatment, this option is not valid for families with low income, and those who can afford it usually choose to have multiple embryo transfers, which has led to an increase in multiple birth rates and increase in the cost of perinatal care. Due to the expected increase in infertility and decrease in the national live birth rate, the United States should set a plan to fund infertility treatment and lead a policy for single embryo transfer.

Alterations in thyroid hormone (TH) status during developmental or adult age are associated with abnormal gonadal development and function in human and animal models. In the developing testis, aberrant levels of TH action lead to disruptions in cell proliferation and differentiation, ultimately influencing testicular size, spermatogenesis, steroidogenesis and male fertility. Recent work is increasingly identifying the systems and signaling pathways in gonadal cells that are affected by TH, as well as delineating the major factors that determine TH signaling in gonadal tissue.
