hi found you this on wikipedia in humans induced lactation and relactation have been observed frequently in primitive cultures and demonstrated with varying success in adoptive mothers. it appears plausible that the possibility of induction of lactation in women (or females of other species) who are not biological mothers does confer an evolutionary advantage especially in groups with high maternal mortality and tight social bonds. the phenomenon has been also observed in most primates in some lemurs and in dwarf mongooses. lactation can be induced in humans by a combination of physical and psychological stimulation by drugs or by a combination of those methods. some couples may stimulate lactation outside of pregnancy for sexual purposes. now what is above may sound a bit odd now read this bit below the stimulation need not be intentional epidermal touching such as with finger tips tongue or lips. mental stimulation with normal brushing of nipples against the inside of brassiers can induce lactation. of course it may be embarrasing but you should not be scared. if it really bothers you try avoiding sexual thoughts or remove focus on some one you find attractive. wear a bra one size larger etc. have also found you this. lactating is linked to the hormone named "prolactin". only when that hormone is very high you can lactate. in a normal situation that hormone is high during last months of pregnancy and after the child is born. and continues to be high for the duration of breast feeding. if the prolactin is high without pregnancy/child breast feeding it means that your hormonal system is out of balanced in a big way! simple blood tests with your md (full hormonal pannel blood tests) will you closer to a diagnosis. the causes of your hormonal being out of balance can be multiple and it is true (somebody mentioned) that pituitary tumor is one of them also hypothyroidism is another one. in my practice i see a lot of women that have adrenal fatigue (do not ask you md about it because they do not study in school such thing only alternative practitioners) and/or hypothyroidism. the most common cause is long term stress. untreated it will eventually get to sterility and very early menopause. if you are talking about a pituitary tumor there is medication and holistic (natural) way of treating it before surgery. in fact for all hormonal imbalances there are alternative natural ways of balancing. this last part come from steady health. see so it could be you just out of balance with your hormones. interesting and do hope it helps you. good luck
i've been lactating for over 2 years and have never been pregnant. i started randomly lactating around 2 years ago. the best answer i got at the time from my primary care doctor was that a prescription medicine i was on at the time (either geodon or trazadone) was causing this. i've been prescription drug free for over a year and the lactation is still happening. also i started taking both meds roughly 1. 5 years prior to lactating. i've never been pregnant ever. any thoughts on why this is still happening how to make it stop and side effects from this?
