There is some conflict of opinion and statistical data as regards the connection between women suffering from Polycystic Ovarian Syndrome (PCOS) and their ability to breastfeed.
While some women with PCOS seem to be able to produce quite enough milk for their child, others seem to produce too little to sustain an infant, others actually seem to produce an overabundance of milk for the requirements.
The reason that milk production could be inhibited due to the presence of PCOS, is due to the fact that estrogen levels may be elevated, which can result in less milk being produced.
Also if a woman has had PCOS for a long time, it could be that the mammary gland development was negatively impacted which in turn enables inadequate milk production.
Low or inadequate milk production does not have to be a cause for any major concern, because even if a woman is not able to produce all the milk that her infant requires, she may still be able to produce enough to provide the baby with a lot of the many benefits of breastfeeding, such as building immunity and increasing bonding. The shortfall can be made up using formula.
