Is induced abortion a contributing factor to tubal infertility in Mexico? Evidence from a case-control study

Microbiological composition of follicular fluid in patients undergoing IVF and its association with infertility

PROBLEM

In recent years, the incidence of female infertility has risen sharply, which is affected by many factors. It was recognized that female reproductive tract microbes play a role in the process of female conception. If the reproductive tract microbes could solve a certain proportion of infertility, it would certainly reduce the pain and economic burden of many patients. The objective of this study was to investigate the microbial community composition of follicular fluid in infertile patients and its potential impact on infertility.

METHOD OF STUDY

Follicular fluid from 49 primary infertility and 52 secondary infertility patients was collected by a negative pressure needle, and the microbiota was analyzed by 16S rDNA sequencing.

RESULTS

It was found that Lactobacillus, especially L. crispatus, might have a positive effect on female pregnancy. Considering the presence or absence of male factors and different body mass indices, L. iners might inhibit female pregnancy. However, L. iners seemed to play a positive role in egg maturation, while Gardnerella and Cutibacterium acnes might have a negative effect on female pregnancy.

CONCLUSIONS

This study suggested the potential role of Lactobacillus in follicular fluid in improving female infertility and provided a theoretical basis for the future microbiological treatment of female infertility.

Towards a better understanding of abortion misinformation in the USA: a review of the literature

Roughly 20% of women in the USA will seek an abortion during their lifetimes. As abortion is a medical procedure, individuals seeking abortion services must have access to accurate medical information. Inaccurate information about abortion, known as abortion misinformation, adversely affects knowledge about abortion, and may impair informed decision-making. Abortion misinformation has received limited attention in psychological and health research. This review summarises current findings on abortion misinformation from studies of adults in the USA, examines which forms of misinformation are most common, and assesses prominent sources of abortion misinformation. A narrative, integrative approach was adopted focussing on nine articles. Findings suggest that first, inaccurate beliefs about abortion exist among many samples of US adults, including inaccurate connections between abortion and breast cancer, infertility and negative mental health outcomes. Second, abortion misinformation comes from a variety of informational sources, which may render efforts to prevent it challenging. Summarising and extending knowledge of abortion misinformation may be useful first steps to better understanding this phenomenon and may ultimately aid in reduction of abortion misinformation among individuals living in the USA.

Prior surgical uterine evacuation of pregnancy and infertility: protocol for systematic review and meta-analysis

INTRODUCTION

Prior surgical uterine evacuation is associated with an increased risk of infertility. However, findings are inconsistent, highlighting the need for a clear consensus on the effect of prior surgical uterine evacuation on the risk of infertility. Therefore, the aim of this systematic review and meta-analysis is to summarise the available evidence examining the association between prior surgical uterine evacuation and the risk of infertility.

METHODS AND ANALYSIS

A systematic search of electronic databases (ie, PubMed, Scopus, ClinicalTrials.gov, EMBASE and ScienceDirect) will be conducted since their inception until October 2019 with no limit for language using a detailed prespecified search strategy. Both the authors will independently screen titles and abstracts and select full-text articles, perform data extraction and appraise the quality of included studies using a bias classification tool. Meta-analyses will be performed to calculate the overall pooled estimates using the generic inverse variance method. This systematic review and meta-analysis will follow the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) guidelines.

ETHICS AND DISSEMINATION

Given that this is a protocol based on published data, there is no requirement for ethics approval. It is anticipated that the dissemination of results will be reported according to the PRISMA statement. The results will be published in peer-reviewed journals and presented at scientific conferences.

Induced abortion and future use of IVF treatment; A nationwide register study

OBJECTIVE

In this nationwide study we assessed the use and factors associated with future in vitro fertilization (IVF) treatment after induced abortion.

MATERIALS AND METHODS

The study population was collected by means of record linkage between Finnish national registers. All women who underwent induced abortion between 2000 and 2009 in Finland were identified through the Register of Induced Abortions (n = 88 522). The study group consisted of women who underwent induced abortion and subsequently had an IVF treatment (n = 379); the comparison group were all women who had a spontaneous pregnancy and delivery 12-24 months after the index abortion (n = 7434). Demographic characteristics at the time of index abortion, and factors associated with the abortion (gestational age at abortion, indication and method of abortion, complications after abortion) were compared between the study groups. Logistic regression was used to assess whether some of the demographic characteristics or abortion associated factors increased the use of IVF treatment in the future.

RESULTS

The proportion of women with IVF treatment after induced abortion in the whole cohort was 0.4%. Women needing IVF treatment were older, of a higher socioeconomic status, and had fewer previous induced abortions and deliveries compared to women in the comparison group. No statistically significant differences were observed in the gestational age (≤ 12 weeks or >12 weeks of gestation) at abortion, method or complications of abortion. In multivariable analysis higher age increased, and history of previous deliveries or one or two abortions decreased the use of IVF.

CONCLUSIONS

Infertility necessitating the use of IVF treatment after induced abortion is uncommon. The factors associated with use of IVF after abortion are those generally recognized as risk factors of infertility. Abortion-related outcomes are not associated with an increased need of future IVF-treatment.

The root of reduced fertility in aged women and possible therapentic options: current status and future perspects

It is well known that maternal ageing not only causes increased spontaneous abortion and reduced fertility, but it is also a high genetic disease risk. Although assisted reproductive technologies (ARTs) have been widely used to treat infertility, the overall success is still low. The main reasons for age-related changes include reduced follicle number, compromised oocyte quality especially aneuploidy, altered reproductive endocrinology, and increased reproductive tract defect. Various approaches for improving or treating infertility in aged women including controlled ovarian hyperstimulation with intrauterine insemination (IUI), IVF/ICSI-ET, ovarian reserve testing, preimplantation genetic diagnosis and screening (PGD/PGS), oocyte selection and donation, oocyte and ovary tissue cryopreservation before ageing, miscarriage prevention, and caloric restriction are summarized in this review. Future potential reproductive techniques for infertile older women including oocyte and zygote micromanipulations, derivation of oocytes from germ stem cells, ES cells, and iPS cells, as well as through bone marrow transplantation are discussed.

Association between history of abdominopelvic surgery and tubal pathology

BACKGROUND

Pelvic infection, unsafe abortion and previous laparatomy are risk factors for tubal infertility among Nigerian women. Reports on the relationship between these factors and tubal pathology seen on hysterosalpingography (HSG) from our environment have been few.

OBJECTIVE

To assess the prevalence of tubal occlusions among patients referred for HSG and examine the association between previous history of abdominopelvic surgery (including dilatation and curettage for abortion) and tubal occlusion.

METHODS

We studied one hundred and thirty women referred to the Radiology department for HSG because of infertility. HSG was performed during the early proliferative phase of the menstrual cycle. Information about type and duration of infertility, history of abdomino -pelvic surgery and history suggestive of previous pelvic infection, were obtained from the patients. The data obtained were analyzed using SPSS version 11. Test of association using the chi-square test was done where appropriate and differences were considered at p= 0.05.

RESULTS

Sixty one women had bilaterally patent tubes; tubal pathology was seen in sixty nine women. Significant association exits between tubal pathology and history of pelvic surgery p=0.01, pelvic infection p=0.02 and duration of infertility p=0.04.

CONCLUSION

Previous surgery especially dilation and curettage, PID duration and type of infertility are associated with tubal pathology among Nigerian women. Creative methods of lowering the cost of diagnosis and management of tubal occlusion need to be instituted.

The Diagnostic Properties of Medical History in the Diagnosis of Tubal Pathology among Subfertile Patients

Objectives. To evaluate the diagnostic performance of medical history in the diagnosis of tubal pathology among subfertile patients. Patients and Methods. Prospective cross-sectional study was performed. Prior to tubal evaluation, medical history data were collected. Sensitivity, specificity, and likelihood ratios (LRs) for predicting tubal pathology as determined by laparoscopy and dye test were calculated for each issue of medical history. Results. 39.6 % (59/149) were diagnosed with tubal pathology. The sensitivity for the different issues ranged between 1.7 and 54.2% and the specificity between 75.6 and 97.8%. The estimated highest value of positive LR is attributed to the history of ectopic pregnancy and lowest of negative LR to pelvic inflammatory disease (PID) and abdominal surgery. Conclusion. The positive history of PID, sexually transmitted diseases (STDs), abdominal and laparoscopic surgery, and ectopic pregnancy are satisfactory screening tests for ruling the tubal pathology in. The negative history of evaluated issues is inappropriate for ruling the tubal damage out.

The value of medical history taking as risk indicator for tuboperitoneal pathology: a systematic review

BACKGROUND

Guidelines recommend diagnostic laparoscopy in subfertile women with known co-morbidities in their medical history. Aggregated evidence underpinning these recommendations is, however, currently lacking.

OBJECTIVE

The objective of this study was to perform a systematic review and meta-analysis of the available evidence on the association between items reported during medical history taking and tuboperitoneal pathology.

SEARCH STRATEGY

MEDLINE (from 1966 to May 2007), EMBASE (from 1960 to January 2007) and bibliographies of retrieved primary articles.

SELECTION CRITERIA

All relevant studies that compared medical history with the presence or absence of tubal pathology.

DATA COLLECTION AND ANALYSIS

Studies comparing medical history with the presence or absence of tubal pathology were included. A diagnosis of tubal pathology had to be made by hysterosalpingography, laparoscopy or a combination of both. In the absence of invasive tubal testing, tuboperitoneal pathology was considered to be absent in case of intrauterine pregnancy. Homogeneity between studies was assessed, and the association between medical history and tubal pathology was expressed as a common odds ratio with a 95% CI. No language restriction was applied.

MAIN RESULTS

We included 32 studies. In cohort studies, strong associations were found for a history of complicated appendicitis (OR 7.2, 95% CI 2.2-22.8), pelvic surgery (OR 3.6, 95% CI 1.4-9.0) and pelvic inflammatory disease (PID) (OR 3.2, 95% CI 1.6-6.6), and in case-control studies, for a history of complicated appendicitis (OR 3.3, 95% CI 1.8-6.3), PID (OR 5.5, 95% CI 2.7-11.0), ectopic pregnancy (OR 16.0, 95% CI 12.5-20.4), endometriosis (OR 5.9, 95% CI 3.2-10.8) and sexually transmitted disease (OR 11.9, 95% CI 4.3-33.3).

AUTHOR'S CONCLUSIONS

Subfertile women reporting a history of PID, complicated appendicitis, pelvic surgery, ectopic pregnancy and endometriosis are at increased risk of having tuboperitoneal pathology. In these women, diagnostic laparoscopy should be offered early in the fertility work-up.

[A study comparing previous induced abortion rates in populations of newly delivered women and infertile women]

OBJECTIVE

For years, induced abortions (IA) have been deemed responsible for altered fertility. The implication of various mechanisms including tubal infertility, intra-uterine adhesions, spontaneous abortion, ectopic pregnancy, cervical incompetence, shortened gestations, and any psychological trouble leading to anovulation has been raised. Though many authors find no evidence of an increased risk on fertility for women, whose IA is not complicated by infection, it might sometimes be insinuated that infertility is the consequence of previous abortion. Thus, we compared the rate of patients with any prior IA in a population of newly delivered women and in women ongoing IVF.

PATIENTS AND METHODS

A retrospective study was conducted at Sèvres hospital, comparing two populations of women, newly delivered women (n=1738) between January 1st and December 31st 2005, and women ongoing IVF at the same period (n=430). We reported the number of previous medical or surgical induced abortions and compared it in both groups. Another analysis compared these rates, among two subgroups of women with one or more prior pregnancy (secondary infertility (n=148), and secondary gestation (n=1088).

RESULTS

The rate of prior IA was not different in the two populations. In the IVF group, 13% (n=56) had undergone one or more IA, versus 16.7% (n=291) in the newly delivered group (P=0.06). Among women with previous pregnancy, 37.8% (56) women of the IVF group had undergone one or more previous IA, versus 26.7% (291) of the newly delivered women (P=0.007).

DISCUSSION AND CONCLUSION

As expected by literature data on IA and fertility, rates of prior induced abortions were not different in the population of fertile women versus infertile. However, women with one or more previous pregnancy are more likely to have undergone previous IA in the IVF group than in the newly delivered group, possibly due to a bias of age. More data are requested to eliminate linkage between IA and infertility.

Modifiable risk factors for impaired fertility in women: What nurse practitioners need to know

PURPOSE

To provide an overview of impaired fertility in childbearing-aged women, to review the current research on modifiable lifestyle risk factors implicated in its development, and to suggest strategies for nurse practitioners (NPs) to assist women in behavioral changes that will allow them to protect their fertility.

DATA SOURCES

Original research articles and comprehensive review articles identified through Medline, CINAHL, and OVID databases.

CONCLUSIONS

Research has shown that advancing age, a history of a sexually transmitted infection and/or pelvic inflammatory disease, extremes of body weight, and tobacco and caffeine use are potentially modifiable risk factors in the development of impaired fertility.

IMPLICATIONS FOR PRACTICE

NPs must be aware of the link between these behaviors and the development of impaired fertility in order to assist women in preserving their fertility. Individual counseling, education, and community-wide education strategies are discussed.
