It’s the phenomenon taking social media by storm: women who previously struggled with infertility are reporting unexpected pregnancies after taking GLP-1 receptor agonists (GLP-1RAs) like Ozempic, Wegovy, or Mounjaro. This “Ozempic Baby Boom” has left many patients with questions.
“As the Medical Director at Laurel Fertility Care, I want to clarify the mechanisms behind this, dispel myths, and help you align these medications with your family-building goals using the latest clinical evidence,” said Dr. Smikle.
Why is this happening? Two key factors
The rise in unexpected pregnancies is likely due to a combination of two distinct factors: metabolic restoration and medication interference.
1. Restored ovulation through metabolic health
For many women, the path to pregnancy is blocked by conditions related to metabolic health, particularly obesity and Polycystic Ovary Syndrome (PCOS). GLP-1RAs improve reproductive outcomes primarily through weight loss and enhanced insulin sensitivity.
- Hormonal regulation: These agents have been shown to reduce androgen levels and improve menstrual regularity, particularly in women with obesity and/or PCOS.
- The “reset”: As metabolic health improves, women who were previously anovulatory (not releasing eggs) may experience a spontaneous restoration of ovulation and conception rates.
- Endometrial health: Some studies also suggest these medications may offer immunological and vascular benefits that enhance endometrial receptivity and implantation.
2. GLP-1s may interfere with oral contraception
This is a critical point often overlooked. GLP-1RAs work by slowing down digestion, known as delayed gastric emptying. This directly impacts how your body absorbs oral medications.
- Reduced absorption: The “slowing” effect means your body may not effectively absorb oral contraceptives, leading to reduced efficacy.
- High-risk scenario: This interaction is most relevant for oral birth control pills. For patients using these pills while on GLP-1 therapy, the risk of unintended pregnancy increases significantly.

A critical warning: These are not fertility drugs
While the restoration of ovulation is a positive outcome for general health, it is crucial to understand that GLP-1 agonists may be contraindicated during pregnancy.
Current safety data indicates:
- Lack of human data: There is currently a lack of robust human safety data for use during pregnancy.
- Animal studies: Animal studies, using higher doses of the medications than are currently prescribed, have demonstrated fetal toxicity, early pregnancy loss, and fetal abnormalities, particularly when associated with significant maternal weight loss.
- Contraindications: These medications should not be used during pregnancy or breastfeeding due to these potential risks.
Your game plan: Preconception optimization
The most effective way to use GLP-1RAs is for preconception optimization—using them to improve your metabolic health before attempting to conceive.
If you are NOT planning a pregnancy:
- Prioritize contraception: Given the absorption issues with oral pills caused by delayed gastric emptying, oral contraception alone may not be reliable.
- Switch methods: Speak to your provider about non-oral, long-acting reversible contraceptives (LARCs) such as an IUD, implant, or injection, which are not affected by digestion.
If you ARE planning a pregnancy:
- The washout period: Current guidelines recommend discontinuing GLP-1RAs prior to conception. You need a “washout period” of at least 2 – 4 weeks to ensure the drug is out of your system before fetal exposure occurs.
- Transition care: We may need to transition you to alternatives for glycemic management, such as metformin, which has an established safety profile for the preconception period.
- Monitor for rebound: Discontinuation can lead to rebound weight gain or hyperglycemia, so close monitoring during this transition is essential.
We are here to guide you
Navigating new medications alongside your reproductive goals can be complex. While GLP-1RAs offer significant benefits for women with obesity-related infertility or PCOS, they require careful management to ensure safety.
If you are currently taking a GLP-1 agonist and have questions, contact the team at Laurel Fertility Care. We can help you create a timeline to safely discontinue the medication and optimize your fertility journey.
