As indicated above, ACTH is a cleavage product of the pro-hormone, proopiomelanocortin (POMC), which also produces other hormones including α-MSH that stimulates the production of melanin . A family of related receptors mediates the actions of these hormones, the MCR, or melanocortin receptor family. These are mainly not associated with the pituitary - adrenal axis. MC2R is the ACTH receptor . While it has a crucial function in regulating the adrenal, it is also expressed elsewhere in the body, specifically in the osteoblast , which is responsible for making new bone, a continual and highly regulated process in the bodies of air-breathing vertebrates.  The functional expression of MC2R on the osteoblast was discovered by Isales et alia in 2005.  Since that time, it has been demonstrated that the response of bone forming cells to ACTH includes production of VEGF , as it does in the adrenal. This response might be important in maintaining osteoblast survival under some conditions.  If this is physiologically important, it probably functions in conditions with short-period or intermittent ACTH signaling, since with continual exposure of osteoblasts to ACTH, the effect was lost in a few hours.
Secondly, I wouldn’t be concerned whether or not you’re shedding. Some people shed a little bit, and some people don’t — but shedding is definitely NOT always a good sign (as you know). Some shedding is normal because of the nature of the massages. However, some people also shed because they create too much friction on the scalp skin, or they don’t allow for enough recovery time in between sessions. That’s not the good type of shed. So, don’t worry about not shedding 🙂 Regrowth is possible with or without the type of shedding you’re looking for.
Currently various reproductive options are available to families. The preconception options include MicroSort which is a technology that can separate sperm containing X chromosomes allowing for an increase in chances of having a female. The second reproductive option is preimplantation genetic diagnosis (PGD), which is a technique that can allow the cells of a fertilized egg to be tested to determine if it contains a change in the DMD gene and then implant those eggs which do not. The post conception options include Chorionic Villus Sampling (CVS) and amniocentesis which analyze sampled cells derived from the developing fetus.
