Résumé
After the birth of a child, resuming sexuality can be a time of apprehension for many women. Lack of libido, vaginal dryness or dyspareunia during intercourse. More and more women are experimenting with breastfeeding after the birth of their child, as recommended by the WHO since 2001. The impact of breastfeeding on sexuality is still a controversial subject. Our aim is to compare the sexual function of breastfeeding and non-breastfeeding women in the postpartum period. Method: this literature review was carried out using the "Pubmed", "Science Direct" and "Google Scholar" databases. Only studies conducted between 1993 and 2023 and written in English or French were selected. A total of 18 articles were selected and analyzed. Results: we found a decrease in sexual function in breastfeeding women compared with formula feeding. The areas most affected were sexual desire and lubrication. For sexual satisfaction and orgasm, however, the results were more contradictory. Discussion: breastfeeding does indeed appear to reduce women's sexual function in the postpartum period, particularly desire and lubrication. Further studies, taking into account factors such as parity and the presence of ante-partum sexual dysfunctions, would seem pertinent. Studies with a higher level of evidence would also be needed to confirm these results. Finally, it would seem vital to better inform and warn women on this subject, as more and more women are breastfeeding, so the midwife has a vital role to play in the postpartum period.
