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
This thesis work is focused on studies of sperm antigen: its purification and antifertility effect, its "internal image" by use of anti-idiotypic antibodies, and its capacity to induce antibodies of IgA class. Mouse sperm acrosomal antigens that react with a monoclonal antibody generated against mouse spermatozoa, MS 207, were purified by immunoaffinity chromatography from soluble fraction of mouse testis homogenates.

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.
