Posology and Method of Administration
Treatment should only commence after expert assessment.
In the Female
Induction of ovulation: 10000 units midcycle if plasma oestrogen levels are favourable following follicular stimulation.
In the Male
Delayed puberty: Dose should be titrated against plasma testosterone, starting with 500 units twice weekly. Treatment should be continued for 4 6 weeks.
Undescended testes: Treatment should begin before puberty, the optimum age range being 7 10 years. 500 units three times weekly is a suitable starting dose. This may be increased to 4000 units if necessary. Treatment should continue for 6 10 weeks.
In males over 17 years of age a commencing dose of 1000 units twice weekly can be given. Treatment should be continued for one or two months after testicular descent.
Oligospermia: Dose should be titrated against seminal analysis starting with 500 units two or three times weekly. Treatment should be continued for 16 weeks.
Choragon is given by intramuscular injection.
hCG should not be given to patients with disorders that might be exacerbated by androgen release.
Special Warnings and Precautions for Use
hCG should be given with care to patients in whom fluid retention might be a hazard, as in asthma, epilepsy, migraine or cardiac or renal disorders.
Allergic reactions may occur and patients thought to be susceptible should be given skin tests before treatment.
hCG preparations should only be used under the supervision of a specialist having available adequate facilities for appropriate laboratory monitoring.
In the female Use in induction of ovulation may result in ovarian enlargement or cysts, acute abdominal pain, superovulation or multiple pregnancies, particularly if endocrine monitoring is inadequate.
In the male Treatment for undescended testes may produce precocious puberty; use should cease immediately. Gynaecomastia has been reported. A growth spurt may also be associated with use and this should be kept in mind particularly where epiphyseal growth is still potentially active.
