BACKGROUND: Recombinant human luteinizing hormone (rLH) was originally introduced to supplement recombinant human follicle-stimulating hormone (rFSH) for controlled ovarian stimulation (COS) in patients with hypogonadotropic hypogonadism. P…

BACKGROUND: Endometriosis and adenomyosis are estrogen-dependent inflammatory conditions frequently associated with impaired fertility. Although progesterone resistance at the tissue level is well documented, it remains unclear whether thes…

INTRODUCTION: Several studies indicate that a specific genotype profile could influence ovarian sensitivity to exogenous gonadotropin. However, most of the previous studies were observational and retrospective and thereby more prone to bias…

Abstract Study question Are progesterone levels lower in women with endometriosis or adenomyosis undergoing an embryo transfer compared to unaffected? Summary answer Progesterone levels before embryo transfer in women with adenomyosis and e…

Day 3 embryo quality is a predictor of in vitro fertilization (IVF) success rates in cleavage-stage embryo transfer. However, the association between day 3 embryo quality and clinical outcomes in blastocyst transfer policy is largely unknow…

Endometriosis and autoimmune diseases share a hyper-inflammatory state that might negatively impact the embryo-endometrium crosstalk. Inflammatory and immune deregulatory mechanisms have been shown to impair both endometrial receptivity and…

PURPOSE: To evaluate the association between progesterone (P) level on the day of trigger and time to blastulation in IVF cycles. METHODS: This was a retrospective cohort study with autologous IVF cycles performed at our Institution from J…

BACKGROUND: Specific polymorphisms might influence controlled ovarian stimulation in women undergoing assisted reproductive technologies (ARTs). Data regarding possible interactions of these polymorphisms are still scanty. The aim of this a…

PURPOSE: To evaluate the association between serum progesterone (P) at the day of ovulation trigger and neonatal birthweight in singletons born after frozen-thawed embryo transfer in segmented ART cycles. METHODS: A retrospective multicent…

Sarcomas are relatively common in the young and their treatment can impair fertility. Fertility preservation can be achieved via the cryopreservation of gametes after controlled ovarian stimulation before cancer treatment. A reduced respons…

Abstract Study question To evaluate whether the presence of concomitant autoimmunity in endometriosis patients may affect In Vitro Fertilization (IVF)/Intracytoplasmic Injection (ICSI) outcomes. Summary answer In ‘normo-responders’ patients…

Pathogenesis of endometriosis is still unclear and a role of both innate and adaptive immune system has been postulated. Some recent findings have revealed an increased risk to have concomitant autoimmune disease in women with endometriosis…

Abstract Study question To investigate differences in In Vitro Fertilization (IVF)/Intracytoplasmic Sperm Injection (ICSI) outcomes between endometriosis women who do or don’t have a concomitant autoimmune disease. Summary answer Despite a …

BACKGROUND: The advent of flexible CO2 laser fiber to gynecology arena might represent a turning point in the use of laser energy on a large-scale basis in gynecological surgery. However, there might be some concerns regarding the degree of…

Endometriosis is an estrogen-dependent chronic inflammatory condition that affects women in their reproductive period causing infertility and pelvic pain. The disease, especially at the ovarian site has been shown to have a detrimental impa…

Cycles with progesterone elevation during controlled ovarian stimulation (COS) for IVF/ICSI are commonly managed with a "freeze-all" strategy, due to a well-recognized detrimental effect of high progesterone levels on endometrial receptivit…

Background Endometriosis is inherited as a complex genetic trait, and the single nucleotide polymorphism (SNP) rs61764370 within the KRAS gene on chromosome subband 12p12.1 has been proposed as a potential candidate gene. By disrupting a bi…

Accumulating evidence from animal and human studies suggests that vitamin D is involved in many functions of the human reproductive system in both genders, but no comprehensive analysis of the potential relationship between vitamin D status…

Controversy exists regarding the pathogenesis of endometriotic ovarian cysts. Different and complex theories have been proposed over the years since the description of chocolate cysts by Sampson in 1921. We have herein reviewed findings in …
