This article presents reviews of literature sources on the issue of assessing the risk of developing gynecological cancer in women after an in vitro fertilization program. Infertility and infertile marriages have now become quite a big problem of modern medicine. Against the background of the unfavorable demographic situation in the Russian Federation, this problem is becoming quite urgent. The main way to solve this situation is assisted reproductive technologies, among which the most common is in vitro fertilization. The in vitro fertilization program is accompanied by a hormonal ovulation stimulation procedure to obtain a female germ cell capable of fertilization. Against the background of the active use of the in vitro fertilization procedure, many patients had concerns related to the risk of developing gynecological cancer after the IVF procedure, which is due to the use of hormonal drugs to stimulate the ovaries. Also of concern is the fact that certain types of cancer, including ovarian cancer, endometrial cancer and breast cancer, are hormone-dependent. In this regard, multiple large-scale studies were conducted, which showed that the risk of developing gynecological cancer is really increased in patients after the in vitro fertilization program. In particular, breast cancer in women after the in vitro fertilization program is more common by 10%, and in women without a history of pregnancy and over the age of 40, it is more common by 31%. The increased risk may be due to age-related vulnerability to the effects of hormones or higher doses of hormones during the IVF procedure. Ovarian cancer and endometrial cancer are also more common in patients after IVF. According to the research results, it is suggested that it is not the IVF procedure itself that causes the development of cancer, but excessive hormonal load of the body, which leads to the launch of carcinogenesis.

ObjectiveWe aimed to examine the association between in vitro fertilization (IVF) and risk of cancers through conducting a meta-analysis of cohort studies.MethodsRelevant studies were identified by using PubMed, ISI Web of knowledge, and Scopus through March 2012. Reference lists from retrieved articles were also reviewed. We included historical cohort studies that reported relative risks (RRs) with 95% confidence intervals (CIs) for the association between IVF and cancer risk. Both fixed- and random-effects models were used to calculate the summary risk estimates.ResultsEight cohort studies involving 746,455 participants were included in this meta-analysis. The overall combined RRs for women with IVF treatment were 0.99 (95% CI, 0.74–1.32) for all-site cancer, 1.59 (95% CI, 1.24–2.03) for ovarian cancer, 0.89 (95% CI, 0.79–1.01) for breast cancer, and 1.07 (95% CI, 0.45–2.55) for cervical cancer. A beneficial effect was shown in the subgroup of breast cancer meta-analysis compared with women who gave birth (RR, 0.79; 95% CI, 0.65–0.95). Excess risk of ovarian cancer was still observed when analyses were restricted to studies with less than 8 years of follow-up (RR, 2.35; 95% CI, 1.03–5.37) and studies including cancer cases diagnosed within 1 year of the IVF treatment (RR, 1.71; 95% CI, 1.22–2.40). No evidence of substantial publication bias was observed.ConclusionsThis meta-analysis suggests that there is no significant association between IVF and cancer risk. A possible beneficial effect was shown in the subgroup of breast cancer meta-analysis. Excess risk of ovarian cancer was observed in the analysis of all the studies and subgroups. Special attention should be made to women who may be diagnosed with cancer during or shortly after IVF treatment. Studies of high methodological quality with larger population and longer follow-up are required to provide more evidences for a better understanding of the association.

Background: Due to the increasing prevalence of infertility, the number of referrals to infertility treatment centers has also increased. Nowadays, assisted reproductive technology (ART), including in vitro fertilization (IVF), is a treatment for infertility or genetic problems. Considering the possible consequences of this method among women undergoing in vitro fertilization (IVF) and kids conceived by IVF, extensive research has been conducted in this regard. Methods: Overall, 100 articles were entered into the study, and relevant articles were searched and extracted from PubMed, Springer, and Google Scholar databases. In IVF procedure, medications such as Clomiphene citrate and gonadotropins are used to stimulate and mature follicles and thus increase ovulation. Results: There are conflicting opinions on this issue. Some findings report a slight increase in cancer risk for hormone-sensitive cancers including breast cancer. The long-term use of IVF medications can increase estrogen hormones and cause excessive expression of genes, resulting in an increased risk of breast cancer, which is one of the most frequent cancers among women. Conclusion: There are some risks to be aware of, which followed the hypothesis that long IVF treatment process may lead to breast cancer among IVF candidates. Furthermore, the risk of breast cancer may be increased in those women with a positive family history and related inherited genes. Therefore, women candidates for IVF should be informed of the probable implications of the reproductive therapy techniques.

AbstractDevelopment of assisted reproductive technologies to address infertility has favored the birth of many children in the last years. The majority of children born with these treatments are healthy, but some concerns remain on the safety of these medical procedures. We have retrospectively analyzed both the fertilization method and the microarray results in all those children born between 2010 and 2019 with multiple congenital anomalies, developmental delay and/or autistic spectrum disorder (n = 486) referred for array study in our center. This analysis showed a significant excess of pathogenic copy number variants among those patients conceived after in vitro fertilization with donor oocyte with respect to those patients conceived by natural fertilization (p = 0.0001). On the other hand, no significant excess of pathogenic copy number variants was observed among patients born by autologous oocyte in vitro fertilization. Further studies are necessary to confirm these results and in order to identify the factors that may contribute to an increased risk of genomic rearrangements, as well as consider the screening for genomic alterations after oocyte donation in prenatal diagnosis.

Context: Infertility is defined as not being able to conceive after one year of unprotected sex. In vitro fertilization (IVF) is a process of fertilization where an ovum is combined with sperm outside the body, in vitro. In vitro fertilization (IVF) is psychologically and emotionally stressful. Coping strategies are needed to master, tolerate, reduce, or minimize stressful events. Aim: This study aimed to evaluate the effect of nursing guidelines on coping of infertile couples' undergoing In Vitro Fertilization. Methods: A quasi-experimental research design was utilized to achieve the aim of this study. This study conducted at the assisted reproductive technology unit of Ain shams Maternity University Hospital on a convenient sample of 98 couples undergoing fertility treatments. Two tools were used for data collection; the first tool was a structured interviewing questionnaire to assess the couple's socio-demographic data, obstetric history, the couple's knowledge regarding in vitro fertilization. The second tool was ways of coping scale (WQS) to assess coping strategies among the infertile couple. Results: There is no statistically significant difference between couples in both groups according to their knowledge and their coping strategies to IVF before the implementation of nursing guidelines (p> 0.05). In contrast, there is a highly statistically significant improvement in knowledge and coping strategies of couples on the study group compared to control group couples after implementation of nursing guidelines(p<0.001). Conclusion: The finding of the current study supported the hypothesis, which stated that the infertile couples who will expose to the nursing guidelines, will exhibit improved coping strategies to IVF compared to the controls. The study recommended the application of nursing guidelines at the IVF unit of Ain Shams Maternity University Hospital and other settings for IVF treatment as routine care to improve infertile couples' coping strategies.

Women conceiving by assisted reproduction are at higher risk for preterm and premature rupture of membranes. The aim of our study was to estimate and compare incidence of preterm premature rupture of membranes in singleton pregnancies of women who conceived by intrauterine insemination and in vitro fertilization, from 1999 to 2003. We investigated 87 women from the intrauterine insemination, and 102 from the in vitro fertilization program. There were no statistically significant differences in regard to preterm and premature rupture of membranes: p>0.75 in two groups. The incidence of premature rupture of membranes was 2.30% (after intrauterine insemination) and 2.94% (after in vitro fertilization). There was no statistically significant differences in regard to preterm and premature rupture of membranes in women who conceived by insemination and in vitro fertilization. Estimated incidence of preterm and premature rupture of membranes was similar to the literature data and also similar to incidence after natural conception.
