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 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 a…
In order to characterize and compare the pattern of inhibin production in the follicular phase between patients of the clomiphene citrate/human menopausal gonadotropin (hMG) and Buserelin/hMG protocols in in-vitro fertilization, serum inhibin levels from 20 patients in each protocol were measured. …
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. H…

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…
It is well established that LH action is mediated primarily by adenylate cyclase/cAMP. Conversely, the role of inositol phosphate/calcium in LH signalling has only recently been investigated. We examined the effects of gonadotrophins on intracellular calcium mobilisation in HEK293 cells transiently…
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. …
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 wi…
These studies examined the effects of prostaglandin-F[sub 2a] (PGF[sub 2a]) on progesterone and 178-estradiol (estradiol) production, as well as DNA and PGF[sub 2a]-receptor (PGF[sub 2a]-R) mRNA levels, in the human granulosa-luteal cell (GLC). Additionally, the interactions of PGF[sub 2a] with hum…
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 i…
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 regul…
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. Seve…
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 suggest…
Epidemiological studies have shown that cholesterol is a major risk factor for the development of atherosclerosis. Since the atherosclerotic plaque develops over a long period interventions early in life may be of some benefit. In addition, it has been shown that the enzymes involved in cholesterol…
Atrial natriuretic peptide (ANP) of atrial myocyte origin, has been shown to play a role in the diuresis, natriuresis, and antagonism of angiotensin and vasopressin. 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 h…
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 disrup…
Aberrant epidermal growth factor receptor (EGFR) activity contributes to the development of epithelial ovarian cancer (EOC), a common and lethal female malignancy. Elucidating the regulation of EGFR function will improve treatments for EOC and the survival of patients. This study aims to elucidate …
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 techno…
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 expre…
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 ex…
