background: c-reactive protein (crp) can be increased after hormonal stimulations. the changes of crp might affect the success of in-vitro fertilization (ivf). objective: the aim of this study was to determine the possible relationship between the serum crp level and outcome of controlled ovarian stimulation, and pregnancy rate in patients undergoing ivf or intra cytoplasmic sperm injection (ic...

This study was designed to evaluate the detrimental effect of atrazine (ATR) on germinal epitheliums (GE) cytoplasmic carbohydrate (CH) and unsaturated fatty acids (UFA) ratio and to clarify the effect of ATR on serum levels of FSH, LH, testosterone and inhibin-B (INH-B). The impact of ATR exposure on total antioxidant capacity (TAC), sperm DNA packing and integrity were also investigated. Seve...

Selection imposed through sperm competition is commonly thought to promote the evolution of longer sperm, since sperm length is assumed to be positively associated with sperm swimming velocity. Yet, the basis for this assumption remains controversial, and there is surprisingly little intraspecific evidence demonstrating such a link between sperm form and function. Here, we show that sperm lengt...

At some point during their reproductive lives, approximately one quarter of all couples experience a period of infertility lasting over one year, leading many to seek council from an infertility specialist.1 For those who need some form of intervention to assist with conception, there are a range of available treatment options, including lifestyle modification, medication, surgery, and a variet...

OBJECTIVE This study aimed to assess the levels of microbial contamination in semen samples before and after the micro swim-up (MSU) procedure in intra-cytoplasmic sperm injection (ICSI). The new method is an upgrade to the classic wash swim-up procedure. METHODS Semen analysis and microbiological tests were carried out before and after the MSU procedure. A total of twenty semen samples were ...

Recent studies have advocated a role for mitochondrial DNA (mtDNA) in sperm competition. This is controversial because earlier theory and empirical work suggested that mitochondrial genetic variation for fitness is low. Yet, such studies dealt only with females and did not consider that variation that is neutral when expressed in females, might be non-neutral in males as, in most species, mtDNA...

The very rapid advancements in assisted reproductive techniques (ART) during the last decades have been driven by a general progress in medical research but also by a great desire of the society to be able to fulfill the basic human need to reproduce. Since the birth of the first IVF-baby in 1978, new techniques such as intra-cytoplasmic sperm injection (ICSI), pregestational diagnosis (PGS) an...

Today, with advances in assisted reproductive techniques, many infertile couples are able to have children. However, there is always risk of passing genetic abnormalities associated with infertility from parents to children. Therefore, detection of microdeletions of Y chromosome in patients with spermatogenesis failure seems very important. The purpose of this study was to determine the frequen...
