Apoptosis in human sperm as a quality marker for a new diagnostic approach of infertile patients
2018
The quality of the sperm DNA is one of the most important molecular markers of male reproductive potential (Bosco, L et al., 2018, Environ Toxicol Pharmacol 58:243-249). The aim of this study was to evaluate sperm DNA fragmentation according to morphology, to predict the probability of selecting a sperm with normal morphology and intact DNA. An observational study was performed on 70 patients with oligoasthenoteratozoospermia. Sperm DNA Fragmentation Index (DFI) and semen parameters such as sperm density, motility and morphology were evaluated in all patients. DFI was calculated using the in situ TUNEL assay. DFI can be determined and thus used as a marker of sperm quality for a diagnostic …
Selection of the best three oocytes for intracytoplasmic sperm injection (ICSI) using apoptotic analysis of cumulus cells
2009
Introduction: We studied the apoptosis rate of the cumulus cells of individual cumulus-oocyte complex (COC), to verify a relationship with clinical outcomes, in terms of pregnancy and implantation rates. Usually oocytes are selected using morphological criteria. We tried to verify if cumulus cell apoptotic rate could be used as a molecular criteria in selecting oocytes with higher implantation potentiality. Material and Methods: The study design consisted in two different trials: in the first we investigated apoptosis rate in cumulus cells of the three selected oocytes, according to Italian law, to be fertilized by intracytoplasmic sperm injection (ICSI). In a second trial, average apoptosi…
Correction to: a predictive model for women's assisted fecundity before starting the first IVF/ICSI treatment cycle.
2019
PURPOSE: To introduce a prognostic model for women’s assisted fecundity before starting the first IVF/ICSI treatment cycle. METHODS: In contrast to previous predictive models, we analyze two groups of women at the extremes of prognosis. Specifically, 708 infertile women that had either a live birth (LB) event in the first autologous IVF/ICSI cycle (“high-assisted-fecundity women”, n = 458) or did not succeed in having a LB event after completing three autologous IVF/ICSI cycles (“low-assisted-fecundity women”, n = 250). The initial sample of 708 women was split into two sets in order to develop (n = 531) and internally validate (n = 177) a predictive logistic regression model using a forwar…
The carriers of the A/G-G/G allelic combination of the c.2039 A>G and c.-29 G>A FSH receptor polymorphisms retrieve the highest number of oocytes in …
2016
The objective of this study was the elucidation of the possible role of the single-nucleotide polymorphisms (SNP) at position -29 and 2039 of the FSH receptor gene (FSHR) as independent predictive markers of ovarian response. Indeed, the tailoring of reproductive treatments is crucial for both maximizing the success of IVF patients and obtaining a reduction in hypo- or hyper-response rates. This prospective, observational study analyzed the association of -29 and 2039 FSHR polymorphisms with the number of retrieved oocytes in 140 patients attending an IVF/ICSI cycle for severe male factors (≤5,000,000 spermatozoa/mL) or tubal factors at the ANDROS Day Surgery Clinic, Palermo, Italy. The res…

Fertility After Ovarian Cystectomy: How Does Surgery Affect IVF/ICSI Outcomes?
2019
Abstract Introduction For patients considering undergoing assisted reproductive techniques (ART), many concerns arise when persistent ovarian cysts are found. This large study aimed to determine how ovarian cyst removal affects success rates of IVF/ICSI therapies. Methods 550 patients who underwent an IVF/ICSI treatment between 2002 and 2011 with a persistent ovarian cyst ≤ 5 cm before treatment were analyzed retrospectively. 328 patientsʼ preference was to undergo a laparoscopic cystectomy and 222 patients opted for a conservative management. Control subjects included 13 552 patients undergoing IVF/ICSI at the same period of time without an ovarian cyst. Results After adjusting for age, pa…
P–409 Comparison of the incidence of ectopic pregnancies in fresh versus frozen embryo transfers in IVF/ICSI cycles: a meta-analysis of Randomized Co…
2021
Abstract Study question Is the incidence of ectopic pregnancy (EP) increased in fresh compared with frozen embryo transfer (ET)? Summary answer The fresh ET is not associated with an increase of the incidence of EP in comparison with frozen ET. What is known already EP represents the first cause of mortality in the first trimester of pregnancy. Assisted reproductive technologies (ART) are associated with an increased EP risk. The reasons of this effect are inadequately explained and may be associated with variables patients-related as tubal diseases and ART-related as the number of embryos transferred, the depth of insertion of the catheter tip during ET and the supraphysiological estradiol…
Health outcomes of children born after IVF/ICSI: a review of current expert opinion and literature
2014
The Sixth Evian Annual Reproduction (EVAR) Workshop Group Meeting was held to evaluate the impact of IVF/intracytoplasmic sperm injection on the health of assisted-conception children. Epidemiologists, reproductive endocrinologists, embryologists and geneticists presented data from published literature and ongoing research on the incidence of genetic and epigenetic abnormalities and congenital malformations in assisted-conception versus naturally conceived children to reach a consensus on the reasons for potential differences in outcomes between these two groups. IVF-conceived children have lower birthweights and higher peripheral fat, blood pressure and fasting glucose concentrations than …
SELECTION OF THE BEST OOCYTES FOR INTRACYTOPLASMICSPERM INJECTION (ICSI) USING APOPTOTIC ANALYSIS OF CUMULUS CELLS
2015
Introduction: We studied the apoptosis rate of the cumulus cells of individual cumulus-oocyte complex (COC), to verify a relationship with clinical outcomes, in terms of pregnancy and implantation rates. Usually oocytes are selected using morphological criteria. We tried to verify if cumulus cell apoptotic rate could be used as molecular criteria in selecting oocytes with higher implantation potentiality (1;2). Materials and Methods: The study design consisted in two different trials: in the first, we investigated apoptosis rate in cumulus cells of the three selected oocytes, to be fertilized by intracytoplasmic sperm injection (ICSI); in a second trial, average apoptosis rate of the cumulu…
P–410 Comparison of the incidence of miscarriage rates in frozen versus fresh embryo transfers in IVF/ICSI cycles: a meta-analysis of Randomized Cont…
2021
Abstract Study question Is the incidence of miscarriage rates increased in frozen embryo transfer (ET) compared with fresh ET? Summary answer The frozen ET is not associated with an increased risk of miscarriage in comparison with fresh ET. What is known already Nowadays, the freeze-all policy has gained great popularity because it minimizes OHSS and it seems to improve the reproductive outcomes. This increase was possible thanks to progress in vitrification procedures. Nevertheless, some recent evidence suggests more caution on the wide use of elective frozen ET in a general IVF population for its possible effect on some pregnancy-related complications. Endometrial preparation schemes for …
