Abstract Background The present study aims to provide a comparative analysis of the etiologies of female infertility between Dehong, on the Yunnan Frontier, and Kunming. Methods A retrospective study, which included 941 infertile females in Kunming who were treated in the First People’s Hospital of Yunnan Province and infertile females who were treated in the local hospital in Dehong from January 2016 to November 2018, was conducted. A comparative analysis of the etiologies of infertility in the two regions was then carried out. Results In patients with primary infertility, ovulation disorder (15.03%) was the main cause of infertility in Kunming, and pelvic inflammatory disease (25.59%) was the main cause in Dehong. With regard to secondary infertility, although pelvic inflammatory disease was the main cause of infertility in both regions, the incidence of intrauterine adhesions in Kunming was significantly higher than in Dehong. Conclusions The etiology of infertility showed different epidemiological characteristics depending on the region, hence individualized treatment should be given accordingly

AbstractParental age at time of offspring conception is increasing in developed countries. Advanced male age is associated with decreased reproductive success and increased risk of adverse neurodevelopmental outcomes in offspring. Mechanisms for these male age effects remain unclear, but changes in sperm DNA methylation over time is one potential explanation. We assessed genome-wide methylation of sperm DNA from 47 semen samples collected from male participants of couples seeking infertility treatment. We report that higher male age was associated with lower likelihood of fertilization and live birth, and poor embryo development (p < 0.05). Furthermore, our multivariable linear models showed male age was associated with alterations in sperm methylation at 1698 CpGs and 1146 regions (q < 0.05), which were associated with > 750 genes enriched in embryonic development, behavior and neurodevelopment among others. High dimensional mediation analyses identified four genes (DEFB126, TPI1P3, PLCH2 and DLGAP2) with age-related sperm differential methylation that accounted for 64% (95% CI 0.42–0.86%; p < 0.05) of the effect of male age on lower fertilization rate. Our findings from this modest IVF population provide evidence for sperm methylation as a mechanism of age-induced poor reproductive outcomes and identifies possible candidate genes for mediating these effects.

5055 Background: The use of infertility drugs (ID) in infertile patients treated conservatively for ovarian malignancies remains theoretically contraindicated. Few recent case reports seem to suggest that ID could be used in patients treated for a borderline ovarian tumors (BOT). The aim of this multicenter retrospective study was to report the outcomes of the largest series of patients with a previous history of a BOT who underwent the use of ID. Methods: A multicenter retrospective study was conducted among centers which participate in the French National Register on In Vitro Fertilization registry to evaluate the outcomes of patients with a previous history of a BOT treated with ID. Four criteria were defined to select cases: 1. Histologic confirmation of BOT, 2. The use of a conservative surgery, 3. The use of ID and 4. A follow-up ≥ 12 months after the end of infertility treatment. Results: Thirty cases fulfilled inclusion criteria. Infertility therapy began in November 1989. Disease stages were: I (n = 20), II /III with noninvasive implants (n = 8) and unknown in 2 cases. The mean number of cycles of ovarian induction per patient was 2.6 (range,1–10). After a median follow-up of 42 months after infertility treatment, 4 recurrences were observed (all of them were borderline tumors on a remaining ovary treated by surgery alone). All patients are currently disease-free. Thirteen patients have since become pregnant. The median interval between treatment of the BOT and the use of ID is shorter in patients who relapsed compared to patients who did not (5 versus 29 months; p=.07). Conclusions: These results suggest that infertility drugs could be safely used in patients who experience infertility after conservative management of an early-stage BOT. A minimal interval should be respected between treatment of the ovarian tumor and the use of infertility drugs in order to decrease the risk of recurrence. No significant financial relationships to disclose.

ABSTRACT Cytogenetic heteromorphisms are described as variations at specific chromosomal regions with no impact on phenotype. The purpose of this study was to investigate the effects of these chromosomal polymorphisms involved in reproductive failure in the Romanian population. One thousand eight hundred and nine infertile patients, who were referred to Life Memorial Hospital, Bucharest, Romania, between January 2008 and April 2011, were investigated in this retrospective study. The frequency of chromosomal polymorphic variations was calculated for these patients. The control group is represented by 1116 fetuses investigated by amniocentesis between January 2009 and April 2011. In this study 122 (6.74%) infertile patients and 63 fetuses (5.65%) showed chromosomal polymorphic variations. The differences between the two groups was not statistically significant (p <0.242) but there was statistical significance for some specific chromosomal polymor- phisms [inv(9),1qh+, 9qh+, fra(17)]. Some chromosomal polymorphic variations appear to be associated with reproductive failure. The statistically significantly higher incidence of heterochromatic variations found in infertile individuals emphasizes the need to assess their role in infertility and subfertility.
