LACTATION

With lactation, elevated prolactin levels with exclusive breastfeeding inhibit
pulsatile secretion of GnRH from the hypothalamus. Effectiveness is dependent
on the frequency (at least every 4-6 hours day and night) and intensity (infant
suckling rather than pumping) of milk removal.

Advantages: enhanced    maternal/infant health, bonding,    and nutrition;  readily

available   and inexpensive;    needs   no  supplies;   free    of  systemic    side    effects;

acceptable  to  all religious   groups

Disadvantages:  high    failure rate    if  not exclusively breastfeeding;  only

reliable    for up  to  six months, no  protection  against STDs
