Abstract
Human newborns exposed in utero to maternally administered SSRIs such as fluoxetine (FX) have an increased risk of adverse pregnancy outcomes including poor neonatal adaptation. This comprises respiratory difficulty, jitteriness, cyanosis when feeding and persists for several days after birth. Several potential mechanisms underlying these symptoms have been proposed: 1) acute toxicity to the drugs (i.e. serotonin syndrome), 2) withdrawal syndrome due to the sudden discontinuation of maternal-fetal placental drug transfer at birth or 3) an SSRIs-elicited alteration in fetal brain development. However, the actual mechanism has not been elucidated.

Abstract
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.

Abstract
The gonadotropin - releasing hormone (GnRH) receptor is a plasma membrane associated receptor and a member of the GTP - binding protein coupled receptor family. The interaction of the ligand, GnRH, and the GnRH receptor is a critical event in the endocrine control of reproduction. This coupling stimulates the synthesis and release of both luteinizing hormone and follicle stimulating hormone from the anterior pituitary. In addition, GnRH - GnRH receptor binding acts locally to regulate human chorionic gonadotropin secretion in the placenta and steroidogenesis in the ovary. The objective of this thesis was to isolate and characterize the gene for the GnRH receptor in human.

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
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.

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.

In the present study, the effects of clomiphene citrate (CC) on ovulation, ovarian growth and ovarian steroidogenesis were examined. Ovulation in rats in response to PMSG was completely blocked by administration of three daily treatments of 1.0 mg CC/rat, but was restored by administration of hCG as a preovulatory LH surge substitute. When the number of treatment days was reduced to two days, 1.0 mg of CC enhanced ovulation in response to PMSG, whereas treatment for one day with the same dose of CC did not affect ovulation.

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.

It is increasingly apparent that GnRH-II acts as an autocrine/paracrine regulator in non-pituitary tissues, in addition to its role in the regulation of gonadotropin synthesis, and is an important player in cancer cell biology. 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.

However, it is now apparent that in addition to the production of the peptide in the heart and in its role in fluid and electrolyte homeostasis, it is also produced in the central nervous system participating in the regulation of pituitary hormone secretion. Administration of ANP through both central and peripheral routes has been shown to inhibit secretion of luteinizing hormone (LH) in the gonadectomized rat model.

Abstract
In-vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) are two of the most common forms of assisted reproductive technologies (ARTs) used to treat human infertility. Presently, over two million children have been conceived by ART. The majority of these children are born healthy. However, IVF and ICSI have been associated with increased risks of adverse perinatal health outcomes. The higher risk of low birth weight, intrauterine growth restriction, and small for gestational age are of special concern due to its association with adult-onset diseases. In this thesis project, the effect of ART on the genetic and epigenetic status of the placenta, and their associations with fetal growth restriction are examined.

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.

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.

Abstract
The placenta is an important endocrine organ producing large amounts of steroid and protein hormones which are released into the maternal and fetal circulations. Moreover, it has a very high metabolic rate and consumes a significant proportion of the oxygen and glucose delivered to the uterus and its contents. However, while there have been many studies on the effects of hypoxemia on fetal cardiovascular, metabolic and endocrine functions, there are limited data on the effects of reduced oxygenation on placental endocrine activities. In the present study, we examined the effects of acute (2-h) moderate (maternal Pao₂ lowered by 27-35%, n=5) and severe (maternal Pao₂ lowered by 41-58%, n=4) hypoxemia on placental progesterone output into the maternal circulation in 7 chronically instrumented pregnant sheep (125 to 136 d). Hypoxemia was achieved by lowering maternal inspired O₂ concentration and the hypoxemia period was preceded and followed by 2 h pre-hypoxia and recovery periods, respectively. Control experiments (n=4), involving 6 h periods of normoxia were also carried out.

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
Light microscopy has remained the primary tool for the assessment of embryo quality and the selection of embryos for transfer in clinical IVF practice. Recent studies have suggested that metabolomic profiling of embryo culture media can distinguish human embryos with better implantation potential. We therefore undertook the following study to further assess the usefulness of metabolomic profiling ?spent? embryo culture medium using Raman spectroscopy. Methods: Patients undergoing IVF+/-ICSI treatment from the UBC Centre for Reproductive Health were recruited for study.
