Abstract
Sex hormone-binding globulin (SHBG) binds androgens and estrogens with high affinity, and regulates the distribution of these sex steroids in the blood and other biological fluids. Liver is the primary site of SHBG production, but the human SHBG transcription unit responsible for this is also expressed in proximal convoluted tubule (PCT) epithelial cells in a transgenic mouse model. Unlike hepatocytes which actively secrete SHBG and retain little immunoreactive SHBG within their cytoplasm, an incompletely glycosylated SHBG isoform has been found to accumulate inside PCT cells. These cells are androgen target cells, and the presence of SHBG within them accentuates androgen-dependent regulation of gene expression mediated by the androgen receptor (AR).

Abstract
Ritodrine is a beta-adrenergic agonist commonly used to inhibit premature labor contractions in women. The primary goal of ritodrine tocolysis is to prolong gestation, however, other indications may include fetal distress. The purpose of the current study was to examine the metabolic and behavioral effects of ritodrine in the fetus, using the chronically instrumented pregnant sheep as an experimental model. Ritodrine was infused continuously into 11 fetal lambs at a rate of 2.6 ug/minute for a period of 8, 12 or 24 hours. Samples were taken simultaneously at predetermined time periods from a fetal femoral artery, umbilical vein, maternal femoral artery and uterine vein for the analysis of fetal and maternal arterial and umbilical and uterine venous blood gases, acid-base status, hematocrit, ritodrine concentration, uterine and umbilical blood flow, and glucose, lactate and oxygen concentrations and fluxes.

Abstract
Superovulation causes detrimental effects, including embryonic loss and implantation failure. This study determined potential roles for insulin-like growth factor (IGF-I) in uterine environment regulation and preimplantation development, in conjunction with the detrimental effects of superovulation in the rat. IGF-I may be beneficial to preimplantation embryonic development. IGF-I stimulated embryonic development and metabolism in vitro and increased the rate of implantation and fetal development when the blastocysts were transferred into a receptive uterus.

Abstract
A delicate balance of steroid and gonadotrophic hormones is essential for intrafollicular oocyte maturation and successful fertilization and embryonic development. Previous studies have demonstrated that a superovulatory dose of pregnant mare serum gonadotrophin (PMSG) has excessive gonadotrophic activity and alters intrafol1icular steroid hormone levels. In a series of four experiments, the morphology of oocytes and embryos retrieved from immature rats, treated with either a low or high dose of PMSG, and mature, cycling rats was compared to determine whether a superovulatory dose of PMSG has an adverse effect on oocyte maturation and subsequent fertilization and embryonic development in immature rats. Morphological criteria for the assessment of intraoviductal oocyte aging were established in the first experiment.

Abstract
Pregnancies derived from in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) are associated with increased rates of chromosome abnormalities, congenital malformations, low birth weight, pre-term births, multiple gestations, and imprinting disorders. Assisted reproductive technologies (ARTs) enable sub-fertile individuals to circumvent the natural selective pressures involved in human reproduction. The risks of ARTs may be due to the underlying causes of subfertility in these individuals or to the artificial processes used to achieve pregnancy. X-chromosome inactivation (XCI) may be at risk to perturbations in ARTs as it is thought to occur during the blastocyst stage when in vitro culturing would be taking place. We examined the XCI status in females conceived by ICSI (n=70), IVF (n=68), and naturally (NC, n=42).

Abstract
Disruptions or imbalances of the vaginal microbiome can lead to negative reproductive health consequences for women, including an increased risk of sexually transmitted infections, pelvic inflammatory disease, and preterm birth. HIV-positive women may be particularly vulnerable to microbiome disruptions due to the immune dysfunction intrinsic to this disease. The objective of this study was to explore the vaginal microbiome in HIV-positive reproductive-aged women utilizing cpn60 metagenomic profiling and to correlate vaginal bacterial profiles with demographic/clinical variables.

Abstract
With the increasing use of assisted reproductive techniques (ART) every year, concerns have been raised regarding the possible effect these procedures have on the health of the children procured by them. Although patients born via ART are usually healthy, studies have associated these procedures with increased incidence of low birth weight (LBW), chromosomal abnormalities, birth defects and imprinting disorders. No study has proposed a single defined cause for any of these defects in ART infants, however it is believed that they may be due to both the invasiveness of ART and to genetic defects that are at the root of the infertility in the parents. In this study, changes in the methylation of the H19 and IGF2 imprinting control region 1 (ICR1) were investigated for both ART (n=92) and naturally conceived controls (n=19) using pyrosequencing.

The distintegrin-like and metalloproteinase with thrombospondin repeats (ADAMTS) are members of a gene family of secreted, multidomain and multifunctional proteinases that are able to proteolytically degrade a diverse array of cellular, extracellular and extracellular matrix (ECM) substrates. We examined the presence of ADAMTS in first trimester human placenta and only ADAMTS-12 was present in cultures of invasive extravillous cytotrophoblast (EVT) at significantly higher levels than in poorly invasive JEG-3 chorocarcinoma cells. Immunohistochemistry staining of chorionic villi derived from first trimester human placenta demonstrated that ADAMTS-12 was intensively immunolocalized in the cytotrophoblast layer but weakly immunolocalized in the poorly-invasive syncytial trophoblast layer.

Abnormal DNA methylation at imprinted and non-imprinted genes has been associated with spermatogenesis failure. However, little information is available regarding DNA methylation at those genes in men affected by severe male factor infertility. We hypothesized a higher incidence of aberrant DNA methylation would be present in the ejaculate and testicular sperm of men affected by severe male factor infertility compared to that in fertile control men. Furthermore, we hypothesized abnormal DNA methylation would also affect non-imprinted genes in the sperm of men affected by severe oligozoospermia.

Abstract
Activin A (homodimer of inhibin βA-subunit) is known to increase inhibin βB-subunit and inhibin B (heterodimer of inhibin α- and βB-subunit) levels and decrease progesterone accumulation in human granulosa cells. Growth differentiation factor 9 (GDF9) is a potent paracrine regulator of ovarian function, but its overall effects, particularly relating to activin A actions, are unknown. We examined the potential crosstalk between activin A and GDF9 in primary cultures of human granulosa-lutein (hGL) cells. Pretreatment of hGL cells with GDF9 for 24 h resulted in an increased expression of activin receptors and Smad2/3, and decreased inhibitory Smad7 activity. These effects were attenuated by BMP type II receptor ectodomain (BMPR2 ECD), a GDF9 antagonist.

High levels of GnRH-II and GnRHR in malignant ovarian tumors as compared with benign ovarian tissues underlies the importance of understanding GnRH-II function in ovarian cancer. In an attempt to define the regulation of GnRH-II in these tissues, we found that a cyclic-AMP responsive element (CRE) is critical for GnRH-II promoter transcription.

The ADAMTS (A Disintegrin and Metalloproteinase with TromboSpondin Repeats) are a novel family of secreted metalloproteinases. There is increasing evidence that distinct ADAMTS subtypes play key roles in embryonic development, reproduction and cancer. Nineteen ADAMTS subtypes have been identified in humans but most of them have been characterized only at the structural level. ADAMTS-1, -4, -5, -8, -9 and -15 have been subclassified into a subfamily, known as aggrecanases, owing to their ability to cleave the important extracellular matrix components, versican and aggrecan.

Ovarian cancer is the most lethal gynecological cancer in the Western world, but comparatively little is known about its development. Epithelial ovarian carcinomas are thought to originate in the ovarian surface epithelium (OSE), i.e. the mesothelium covering the ovary, but experimental evidence for this origin has been lacking. Contrary to most epithelia where neoplastic progression is associated with loss of E-cadherin, this cell-cell adhesion molecule is sparse in normal human OSE but its expression increases in ovarian epithelial metaplasia and neoplasia.

The studies undertaken herewithin sought to characterize the pattern of regulation of the gonadotrophin-releasing hormone receptor (GnRH-R) mRNA levels in the rat ovary. The demonstration of gonadotrophin-releasing hormone (GnRH) transcripts in steroidproducing and steroid-dependent tissues suggests that GnRH may be implicated in the modulation of steroid action in those target tissues. Expression of GnRH-R mRNA increases in gonadal tissues and the pituitary with age, supporting the concept of GnRH as a local regulator in the developing rat as well as in the adult.

Abstract
There is increasing evidence to suggest that activin can function as an autocrine/paracrine regulator in various tissues, including the reproductive system. At the cellular level, activin acts via a family of activin receptor (ActR) subtypes which includes two type I (ActRI and ActRLB) and two type II (II and ILB) receptors. The role of activin in the human placenta is not clearly understood. In this study, the detection of inlubin/activin subunit and ActRI mRNA were examined in first trimester cytotrophoblasts, term cytotrophoblasts, extravillous trophoblast (EVT) cells, immortalized extravillous trophoblast (LEVT) cells, JEG-3 cells, decidual tissue, and decidual cells.
