Assessing both partners
Investigation should reflect the circumstances of the couple. Menstrual history, medical conditions, medicines and appropriate tests guide treatment. Assessing the male partner also matters.
Treatment and the role of weight loss
Depending on the cause, medication, surgery or assisted reproduction may be considered. Weight management may help health and ovulation but does not guarantee a live birth. Delaying treatment solely for weight loss must be weighed against age and fertility circumstances.
Frequently asked questions
Is sleeve gastrectomy a definitive infertility treatment?
No. Bariatric surgery is chosen for its own indications and does not replace specialist fertility assessment.
Can people with obesity have IVF?
Suitability and safety depend on individual circumstances and the treatment centre’s assessment, not a BMI number alone.
Should I wait until I lose weight to seek help?
No. Fertility consultation and weight management can start together so valuable treatment time is not lost.
