Story
Pregnancy Desire and Pregnancy Attempt: Why Words Matter in Reproductive Research -- A Nationwide cross-sectional Cohort Study
Key takeaway
A study found a gap between pregnancy desire and actual attempts among young women, with and without breast cancer history. This highlights the need to consider the nuances of reproductive decision-making for diverse populations.
Quick Explainer
This nationwide study examined the disconnect between women's self-reported desire for pregnancy and their actual attempts to conceive. The researchers quantified this "pregnancy desire-attempt gap", finding it was more common among breast cancer survivors compared to the general population. Several factors appeared to contribute to this gap, including younger age, lack of prior births, being single, and ongoing hormonal therapy. These findings suggest the gap arises from a complex interplay of medical barriers and psychosocial determinants, rather than solely treatment-related effects. Addressing this gap could inform more tailored reproductive counseling and support for cancer survivors and others seeking to start families.

Technical Deep Dive: Pregnancy Desire vs. Pregnancy Attempt in Breast Cancer Survivors
Overview
This nationwide cross-sectional cohort study in France examined the gap between self-reported pregnancy desire and actual pregnancy attempts among women, both with and without a history of breast cancer. The researchers aimed to quantify this "pregnancy desire-attempt gap" and identify demographic, clinical, and treatment-related factors associated with it.
Problem & Context
Reproductive concerns are important for young breast cancer survivors, as the disease and its treatments can impact fertility. However, there is limited data on how this translates to real-world pregnancy planning behaviors. Understanding the factors underlying the gap between desires and attempts could inform supportive care for these women.
Methodology
- The study was conducted as part of the FEERIC cohort study in France.
- Participants were women aged 18-43, both with and without a history of breast cancer.
- Pregnancy desire was assessed by self-report ("Do you currently desire a pregnancy?").
- Pregnancy attempt was defined as engaging in unprotected intercourse with the intention to conceive.
- The "pregnancy desire-attempt gap" was defined as expressing a desire for pregnancy without actively trying to conceive.
- Logistic regression was used to evaluate demographic, clinical, and treatment-related factors associated with this gap.
Results
- Of 4,351 participants (517 breast cancer survivors, 3,834 controls):
- 735 (16.9%) reported a pregnancy desire
- 54% of those with a desire were actively attempting pregnancy
- 46% with a desire were not attempting pregnancy (the "gap")
- The desire-attempt gap was significantly more frequent among breast cancer survivors (OR=1.62, 95%CI[1.15–2.30]).
- In the breast cancer survivor group, the desire-attempt gap was associated with:
- Younger age (<30 years)
- Nulliparity (no prior births)
- Being single
- Ongoing endocrine therapy
- Prior chemotherapy or trastuzumab treatment were not associated with the gap.
Interpretation
This study quantifies a substantial disconnect between pregnancy desires and pregnancy planning behaviors, particularly among breast cancer survivors. Several demographic and treatment-related factors appear to contribute to this gap, suggesting both medical barriers and psychosocial determinants are involved.
Limitations & Uncertainties
- Self-reported measures of pregnancy desire and attempt may not fully capture complex reproductive intentions and behaviors.
- The study population was limited to French women, so results may not generalize to other regions or healthcare systems.
- The cross-sectional design cannot establish causal relationships between factors and the desire-attempt gap.
What Comes Next
The authors highlight the need for further research to explore the underlying reasons for the gap between pregnancy desire and pregnancy attempts, for both breast cancer survivors and the general population. Addressing this gap could inform more tailored reproductive counseling and support.
