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.

Abstract
The common epithelial ovarian tumors appear to arise from the ovarian surface epithelium (OSE), which is a simple squamous-to-cuboidal meso^helium covering the ovary. The exact mechanism of ovarian tumorigenesis is not well known even though this disease is the most frequent cause of cancer death in gynecological malignancies. Repeated ovulation contributes to neoplastic transformation of OSE, indicating that the process of healing ruptured OSE may contribute to the disease. Therefore, it has been hypothesized that endocrine and autocrine factors may influence the occurrence of ovarian tumors in women.

Abstract
Ovarian cancer is the sixth most common cancer and the fifth leading cause of cancer-related death among women in developed countries. There is increasing evidence suggesting that the hormonal environment of the normal ovarian surface epithelium (OSE) and ovarian epithelial cancer (OEC) cells is associated with the development and progression of ovarian cancer. Exposure to excess gonadotropins and leptin, related to menopause or infertility therapy and obesity, respectively, has been implicated as a risk factor for ovarian cancer.

Abstract
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
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.

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.

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.

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
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.

In granulosa cells prelabeled with [³H]-arachidonic acid or [³H]-inositol, treatment with LHRH increased the accumulation of radiolabeled inositol lipids, diacylglycerol and free arachidonic acid, but luteinizing hormone (LH) or cholera toxin did not exert the same effect. Activation of protein kinase C by the phorbol ester, 12-0-tetradecanoyl phorbol-13-acetate (TPA) had a stimulatory action on membrane phosphoinositide breakdown.

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
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).
