Disclai
GnRH Agonists - Lupron, taken as an
injection just below the skin and Synarel, a nasal spray, allow the
body to produce a greater number of high quality eggs during the
treatment cycle. They also prevent the midcycle hormonal surge that can
result in the cancellation of a cycle.
Antagonists - Antagon and Cetrotide
are antagonists of gonadotropin releasing hormone (GnRH) and are used
to prevent premature ovulation. These medications are given by
injection and the duration of treatment is usually three or four days.
Gonadotropins - Gonadotropins are
taken as subcutaneous injections that provide stimulation to the
follicles that contain the eggs during the stimulation phase. Gonal F,
Bravelle, Follistim, Pergonal and Repronex are the most commonly used
gonadotropins.
hCG - hCGs are taken as an
intramuscular injection and are used to induce the final maturational
changes in the eggs and prepare them for retrieval. The most commonly
prescribed hCGs are Pregnyl, Profasi and Novarel.
Medrol - Medrol is a steroid
hormone given daily, typically for a period of four days during the
cycle, to assist pre-embryo implantation.
Doxycycline - Doxycycline, an
antibiotic administered in pill form, is given to the male partner
during the wife's stimulation cycle to reduce the low levels of
bacteria that may be found in the semen and which may compromise the
performance of the sperm during an IVF cycle. It is also given to the
female partner to reduce the risk of infection following aspiration of
the follicles at the time of egg retrieval.
Progesterone - Natural
Progesterone may be taken as a daily intramuscular injection beginning
two days after egg retrieval and continuing until the placenta is
making adequate amounts of Progesterone. Progesterone can also be given
in the form of a vaginal gel or vaginal suppositories or pills
(Prometrium).
