Prolactin is synthesized by Lactotrophs
which initiates milk production together with other mammary gland hormones.
Prolactin which was secreted by the adenohypophysis,
and is made up of 199 amino acids.
Prolactin variation in levels has many effects,
which its levels in the laboratory can esily be detected.
Vital reproduction and lactation can be affected
in newborn babies, males as well as females.
During pregnancy, prolactin levels rise
as the mother's love for the baby never dies.
rising estrogen promotes prolactin release,
causing further mammary glands maturity,
preparing them for lactation for the baby.
After childbirth, prolactin levels fall
but this is normal stimulation for all.
Sucking by the baby on the nipple promotes further prolactin release,
and maintaining the ability to lactate eventually ceases within one or two weeks.
High prolactin levels tend to suppress the ovulatory cycle
by inhibiting both FSH and GnRH.
Too much prolactin can cause galactorrhea
and disturbances in the ovulatory cycle and are often the result of a prolactinoma,
which is a non-cancerous swelling in the pituitary gland.

ReplyDeletei hope i'm good as you.
i like it, hehe
Good poem because it concentrated on yout topic. Just some corrections for typos and errors, see me.
ReplyDeletesuperb poem. you incorporated all the necessary information about your topic into your poem. good job.
ReplyDeleteAnn alexys,
ReplyDeleteI think you are a poet in the making.
lines like this:
During pregnancy, prolactin levels rise
as the mother's love for the baby never dies.
and this
After childbirth, prolactin levels fall
but this is normal stimulation for all.
show that you are trying to make the words rhyme, which is great. Maybe if you can make them uniform. From start to finish.
BTW, you are right in making examples like that because you can't always make your scientific source agree with you, so you can site examples out of your context. That makes the poem more interesting and more enjoyable to read.

"Sucking by the baby on the nipple promotes further prolactin release,
ReplyDeleteand maintaining the ability to lactate eventually ceases within one or two weeks."
I assume you mean that "absent sucking by the baby, the ability to lactate ceases within one or two weeks"? A nursing mother can nurse almost indefinitely, right?
Also, what is the role of oxytocin in lactation? I thought that was what triggered release of prolactin?
Is it true than men can lactate (either as a result of disease or hormonal imbalance, or on purpose in order to breastfeed a child - say, when the mother has died)?
Very interesting post. Thanks for sharing it! It is always a joy to learn something that I didn't know. I have you to thank for teaching me something new, and I appreciate it very much. :-)
