Male infertility:
Spermatogenesis is
stimulated with hCG (1,000 to 2,000 IU hCG 2-3 times per week)
then LG IVF-M™ (Menotropins) (75 IU or 150 IU) is administered 2-3 times per
week. This treatment should be continued for at least 3 months
before any improvement in spermatogenesis can be expected.
Current clinical experience indicates that treatment for at
least 18 months may be necessary to achieve spermatogenesis.
Females with anovulation (including PCOD):
The objective of treatment with LG IVF-M™ (Menotropins) is to develop a
single mature Graafian follicle from which the ovum will be released
after the administration of hCG. LG IVF-M™ (Menotropins) may be given as a course
of daily injections. In menstruating patients treatment should
be started within the first seven days of the menstrual cycle.
The treatment should be adjusted to the individual
patient's response as assessed by measuring follicle size by
ultrasound and/or oestrogen secretion. A commonly used regimen
commences at 75-150IU of LG IVF-M™ (Menotropins) and is increased according
to the patient's response. The maximum daily dose is usually
not higher than 225IU. If a patient fails to adequately respond
after 4 weeks of treatment, the cycle should be abandoned and
the patient should recommence at a higher initial dose than
in the previous cycle.
When an ideal response is obtained a single injection
of 5,000IU-10,000IU of hCG should be administered 24-48hrs
after the last LG IVF-M™ (Menotropins) injection. The patient should be recommended
to have coitus on the hCG injection day and the following day.
Alternatively intrauterine insemination (IUI) may be performed.
In the event of an excessive response treatment
should be suspended and hCG withheld (see warnings). Treatment
should recommence in the next cycle at a lower dose than in
the previous cycle.
Females undergoing controlled ovarian stimulation
for multiple follicular development prior to invitro fertilisation
or other assisted reproductive technologies.
A commonly used protocol for superovulation involves the
administration of 150-225IU of LG IVF-M™ (Menotropins) daily commencing on days
2 or 3 of the cycle and continued until sufficient follicular
development has been achieved as assessed by monitoring of serum
oestrogen concentrations and/or ultrasound examination with the
dose adjusted according to the patient's response but usually
not higher than 450IU daily. Adequate follicular development
is usually achieved by the tenth day of treatment (range 5-20
days).
A single injection of 5,000IU-10,000IU of hCG
should be administered 24-48 hours after the last LG IVF-M™ (Menotropins)
injection to induce follicular maturation.
Pituitary down-regulation in order to supress
the endogenous LH surge and to control tonic levels of LH is
now commonly achieved by administration of a gonadotrophin
releasing hormone (GnRH) agonist. In a commonly used protocol
the administration of LG IVF-M™ (Menotropins) is started approximately two
weeks after the start of agonist treatment, both being continued
until adequate follicular development has been achieved. For
example, following two weeks of pituitary down-regulation with
an agonist, 150-225IU of LG IVF-M™ (Menotropins) are administered for seven
days; the dose is then adjusted according to the patient's
ovarian response.
Experience with ART indicates that in general
the treatment success rate remains stable during the first
four attempts and gradually declines thereafter.
Females with anovulation resulting from severe
LH and FSH deficiency.
In these women (hypogonadotrophic hypogonadism) the objective
of LG IVF-M™ (Menotropins) treatment is to develop a single mature Graafian
follicle from which the oocyte will be released following the
administration of hCG. As these women are amenorrhoeic and
have low endogenous oestrogen secretion treatment may commence
at any time.
The treatment should be adjusted to the individual
patient's response as assessed by measuring follicle size by
ultrasound and/or oestrogen secretion. A commonly used regimen
commences at 75-150IU of LG IVF-M™ (Menotropins) and is increased according
to the patient's response. Should an increased dose of LG IVF-M™ (Menotropins)
be deemed appropriate, dose adaptation should preferably be
made after 7-14 day intervals and preferably by 75IU increments.
It may be acceptable to extend the duration of stimulation
in any one cycle up to 5 weeks.
When an ideal response is obtained a single injection
of 5,000IU-10,000IU of hCG should be administered 24-48hrs
after the last LG IVF-M™ (Menotropins) injection. The patient should be recommended
to have coitus on the hCG injection day and the following day.
Alternatively intrauterine insemination (IUI) may be performed.
Luteal phase support may be considered since
lack of substances with luteotrphic activity (LH/hCG) after
ovulation may lead to a premature loss of the corpus luteum.
In the event of an excessive response treatment
should be suspended and hCG withheld (see warnings). Treatment
should recommence in the next cycle at a lower dose than in
the previous cycle.
Before starting treatment, the couple's infertility
should be assessed as appropriate and putative contraindications
for pregnancy evaluated. In particular, patients should be evaluated
for hypothyroidism, adrenocortical deficiency hyperprolactinemia
and pituitary or hypothalamic tumours, and appropriate specific
treatment given.
Patients undergoing stimulation of follicular
growth whether in the frame of a treatment for anovulatory infertility
or ART procedures, may experience ovarian enlargement or develop
hyperstimulation. Adherence to recommended LG IVF-M™ (Menotropins) dosage and
regimen of administration, and careful monitoring of therapy
will minimize the incidence of such events.
Accurate interpretation of the indices of follicular
development and maturation require a physician who is experienced
in the interpretation of such data
Elevated endogenous FSH levels are indicative
of primary testicular failure. Such patients are unresponsive
to LG IVF-M™ (Menotropins)/hCG therapy Semen analysis is recommended 4-6 months
after the beginning of treatment in assessing the response.
