G.S.
Hello S.,
Every baby girl is born with a fixed number of the eggs (about 2 millions) - all the eggs she will ever have. The number decreases rapidly to about 400,000 in girls just before puberty and later in life it keeps decreasing (only healthy eggs can be selected for fertilization).
So it can be that your friend does not have many healthy eggs left.
But you are right - the situation at the clinic she is attending looks strange. She definitely should consult in other places with other doctors.
Good luck to her!
