What women want? A scoping survey on women's knowledge, attitudes and behaviours towards ovarian reserve testing and egg freezing.

We aimed to investigate women's knowledge, attitudes and behaviours towards ovarian reserve testing and egg freezing for non-medical reasons in the general population. This was a cross-sectional survey study of 663 women aged 18-44 years which assessed female perception of ovarian reserve testing and oocyte cryopreservation. An online forum was used to deliver the survey through the use of two social media sites. Participants were recruited through the technique of "snowballing", whereby existing study subjects recruited others from among their acquaintances. The data collected was analyzed using SPSS to explore descriptive statistics and frequencies relating to the participants' knowledge, attitudes and behaviour towards the practices of ovarian reserve testing and oocyte cryopreservation. Categorical variables were analyzed using Chi-squared; a p-value of <0.05 was considered significant. A majority (60%) of women surveyed had knowledge of ovarian reserve testing. 64.8% would be interested in having testing performed. Younger women (<30 years of age) were more interested in checking their ovarian reserve (75.8% vs. 59.1%, p<0.0001). Single women were also more likely to be interested, (73.6% v's 62.1%, p=0.022). 89.7% of women surveyed were aware of oocyte cryopreservation. 72.2% agreed that they would consider freezing their eggs to preserve fertility. There was no significant difference in the numbers of single women compared to women in a relationship who would consider egg freezing to preserve fertility (75.7% v's 71.2%, p=0.347, or in younger (<30years) compared to older women, (74.7% v's 71.1%, p=0.387). A majority (62.1%) of study participants believed that it is a woman's right to postpone pregnancy for social reasons and to freeze her eggs, with no significant difference in options noted between younger and older women. Knowledge of ovarian reserve testing and oocyte cryopreservation for non-medical reasons were higher than in previous studies, possibly reflecting increasing awareness of these issues among the general public. Additionally, we demonstrated that the women, in our study, were very open to the use of these modern technologies in an attempt to avoid unintended childlessness.

Childless women's beliefs and knowledge about oocyte freezing for social and medical reasons.

What factors inform a woman's decision-making about oocyte freezing to preserve fertility for social and medical reasons? Women lacked knowledge about the costs and viability of oocyte freezing as a fertility preservation option for social and medical reasons, and identified health consequences, costs, and viability as being particularly influential in their decision-making. Having only recently become a viable fertility preservation option, relatively little is known about childless women's beliefs or knowledge about oocyte freezing for social or medical reasons. A cross sectional study of 500 childless women was conducted in August, 2015. A total of 500 childless, presumed fertile, women from 18 to 38 years of age completed an online, self-report questionnaire assessing beliefs and knowledge about oocyte freezing to preserve fertility for social or medical reasons. Financial costs (85.6%), health risks to themselves (86.4%) or their offspring (87.8%), and success rates (82%) were the primary factors that women felt would influence their decision to freeze their oocytes. Partner's feelings (88.6%), prognosis for a full recovery (85.4%), and concerns about the health effects of the hormones or oocyte retrieval procedure (85.4%) were identified as being particularly important when considering oocyte freezing for medical reasons. Consistent with their perceptions of having little or no knowledge about oocyte freezing, there was an overall correct response rate of 33% to the 12 knowledge questions. The online format and use of a survey company to recruit participants may have increased the risk of self-selection bias and limit the generalizability of these findings. The findings may also be limited by the fact that the participants were not facing cancer treatments, and the younger participants were not nearing the end of their reproductive lifespan, and therefore would not have had reason to learn about, or consider, fertility preservation for medical or social reasons. Given the worldwide trend towards delaying childbearing and the increasing availability of oocyte freezing as an option to preserve women's fertility, it is likely these results could be extended to wider North American, European, and Australasian populations of English speaking childless women. No specific funding. No competing interests.

Medical and social egg freezing: internet-based survey of knowledge and attitudes among women in Denmark and the UK.

Until recently, limited options for preserving fertility in order to delay childbearing were available. Although egg freezing and successful thawing is now possible, it remains unclear to what extent women are aware of the availability of this technique, their attitudes towards its use, or the circumstances under which this technique may be considered. An online cross-sectional survey was designed to investigate knowledge and attitudes of women in Denmark and the UK on egg freezing and their potential intentions regarding the procedure. Data was collected from September 2012 to September 2013 and the responses of 973 women were analyzed. In total, 83% of women reported having heard of egg freezing, and nearly all considered it acceptable for medical indications, whilst 89% considered it acceptable for social reasons. Overall, 19% expressed active interest in the procedure, and 27% expressed possible interest. Key factors found to positively influence attitudes to accepting the procedure were reassurance that it would not affect future fertility and greater than 50% chance of achieving a live birth. Characteristics significantly associated with intention to freeze eggs were being single, age under 35 years, childlessness, and a history of infertility. In this group, risk and cost were less important considerations. This study indicates that there is widespread awareness and support of the availability of eggs freezing for reproductive planning. Reassurance regarding its efficacy appears more important than its potential adverse effects on their health or that of future children, or the costs of the procedure.
