Vaccine
Androvax, also known as androstenedione:human serum albumin conjugate, is an
immunogen and
vaccine against
androstenedione that is used in
veterinary medicine to increase the
ovulation rate and number of
lambs born to
ewes.
[1]
[2]
[3] It is a
conjugate of
androstenedione and
human serum albumin.
[1]
[3] The drug is marketed in
New Zealand.
[1]
[3]
Androvax produces
immunity against androstenedione, and the generation of
antibodies against androstenedione decreases circulating levels of androstenedione.
[1] In addition, since androstenedione is the major
precursor of
estrogens, estrogen levels are decreased as well.
[1] This is thought to result in reduced
negative feedback on the
hypothalamic-pituitary-gonadal axis and increased
gonadotropin
secretion, which in turn improves
fertility and
fecundity.
