Why you chose this article and/or how it relates to the clinical issue of interest (include a brief explanation of the ethics of research related to your clinical issue of interest)  


This article examines the genesis of decline of fertility in Europe dating back 18th century. It creates a critical picture of the changes in fertility over centuries.

This article by Garcia and colleagues gives the readers an understanding of how infertility in women came about including the factors that promoted changes in fertility. This book gives a critical perspective of how age affected fertility. Over the past half century there has been a trend towards delayed motherhood. Women who pursue fertility at an advanced age are increasingly common. Family planning and sexual education have traditionally focused on contraception and prevention of sexually transmitted diseases. A focus should now also be placed on fertility awareness and fertility preservation.
Brief description of the aims of the research of each peer-reviewed article Fertility Project. The Project, begun in 1963, was a response to the realization that one of the great social revolutions of the last century, the remarkable decline in marital fertility in Europe, was still poorly understood. The objective of this research was to find out how knowledge of infertility by women help them to make decisions The objective of this work is to examine why women postpone birth or why woman remaining involuntarily childless as well as an increase in pregnancy complications in those that do achieve pregnancy at advanced maternal age. This manuscript aims to give an update on the existing evidence around elective oocyte cryopreservation, also highlighting the need for fertility education and evidence-based, individualized counseling.
Brief description of the research methodology used Be sure to identify if the methodology used was qualitative, quantitative, or a mixed-methods approach. Be specific.  


This project was a quasi-experiment. The methodology used is mixed methods

randomized controlled trials (RCT)-Qualitative research Analysis of existing literature. A thorough electronic search was performed from the start of databases to March 2020 aiming to summarize the existing evidence around elective egg freezing, the logic behind its use, patient counselling and education, success rates and risks involved, regulation, cost-effectiveness, current status and future perspectives.
A brief description of the strengths of each of the research methodologies used, including reliability and validity of how the methodology was applied in each of the peer-reviewed articles you selected.  

This project is valid because it investigators should ensure careful study planning and adequate quality control and implementation strategies-including adequate recruitment strategies, data collection, data analysis, and sample size.

The study draws from peer-reviewed articles that have been reviewed by experts The study draws from peer-reviewed articles that have been reviewed by experts External validity can be increased by using broad inclusion criteria that result in a study population that more closely resembles real-life patients, and, in the case of clinical trials, by choosing interventions that are feasible to apply
