The effects of COVID-19 lockdown on lifestyle and emotional state in women undergoing assisted reproductive technology: Results of an Italian survey.

Purpose: On March 8, 2020, the Italian Government implemented extraordinary measures to limit viral transmission of COV-19/SARS-CoV-2. We evaluated the impact of COVID-19 lockdown on lifestyle and emotional state in women planning infertility treatments.

Basic Procedures: We performed a quantitative research study using a web-based survey, in 140 women referred to Assisted Reproductive Technologies Center.

Cardiometabolic and Thrombotic Risk Profile in Women Undergoing Oocyte Donation for Assisted Reproduction.

The last two decades have seen a growing number of pregnancies in women who needed the donation of oocytes. With oocyte donation pregnancies, studies on obstetric outcomes among these women revealed an increased incidence of pre-eclampsia and pregnancy-induced hypertension. Furthermore, several studies have found a higher incidence of low birth weight, preterm birth, and delivery by cesarean section in oocyte donation rather than in women subjected to assisted reproduction techniques (ART) with autologous oocytes.

'Two countries-two labs': the transnational gamete donation (TGD) programme to support egg donation.

Purpose: To evaluate the effectiveness, efficiency, and safety of a transnational gamete donation (TGD) programme based on the shipping of vitrified donor oocytes.

Methods: A retro-prospective observational study was conducted in the Assisted Reproductive Technology Center of the University Hospital of Florence, Italy. The study population included 622 consecutive donor oocyte cycles.

Bilateral Endometrioma Excision: Surgery-Related Damage to Ovarian Reserve.

To study whether unoperated ovarian endometrioma(s) or its surgical excision led to a modified pattern of ovarian decay with increasing female age. A sectional analysis of basal follicle stimulating hormone (FSH) and ovarian response to gonadotropins was conducted on women treated with fresh autologous In Vitro Fertilization/Intracytoplasmic sperm injection (IVF/ICSI) cycles. The study group included patients with unoperated ovarian endometrioma(s) (108 cycles); control groups were women with previous surgery for monolateral ovarian endometrioma (101 cycles), surgery for bilateral ovarian endometriomas (39 cycles), and tubal factor infertility (171 cycles).

A Biochemical Approach to Detect Oxidative Stress in Infertile Women Undergoing Assisted Reproductive Technology Procedures.

Oxidative stress plays a major role in critical biological processes in human reproduction. However, a reliable and biologically accurate indicator of this condition does not yet exist. On these bases, the aim of this study was to assess and compare the blood and follicular fluid (FF) redox status of 45 infertile subjects (and 45 age-matched controls) undergoing in vitro fertilization (IVF), and explore possible relationships between the assessed redox parameters and IVF outcomes.

Biological meaning of ubiquitination and DNA fragmentation in human spermatozoa.

The ubiquitin-proteasome is an ubiquitous system mainly devoted to protein degradation. The presence of ubiquitinated proteins in male gametes suggests a role for this system also in reproduction. Available evidence indicate that ubiquitin in spermatozoa may have a role in semen quality control, as ubiquitinated defective spermatozoa in the epididymis are subsequently phagocytosed by epididymal epithelial cells.

Lack of Histocompatibility Leukocyte Antigen-G expression in early embryos is not related to germinal defects or impairment of interleukin-10 production by embryos.

The expression of Histocompatibility Leukocyte Antigen (HLA)-G molecules is a mandatory prerequisite for the development of pregnancy but no hypotheses have yet been advanced regarding the lack of HLA-G modulation expression in a percentage of early embryos obtained by in vitro fertilization (IVF). One possible hypothetical model assumes that the absence of regulation of HLA-G or impaired interleukin (IL)-10 secretion could be related to germinal defects. We investigated the presence of soluble HLA-G antigens in supernatants of single embryo cultures from couples admitted to a second fertilization procedure; these couples showed a complete absence of HLA-G modulation in the first cycle's embryo supernatants (0/31).
