Clinical Trial Summary
This study compared the therapeutic effect of 4- and 6-week TTG application before controlled
ovarian hyperstimulation (COH) in POR.
Description:
This randomized control trial (RCT) was conducted between January 2018 and September 2019 at
the National Center for Reproductive Medicine, Hanoi, Vietnam. The eligibility of a total of
165 women with POR, undergoing IVF treatment, to be enrolled in the study was assessed.
Inclusion criteria included patients who met at least two of the following criteria: (i)
having one previous IVF/ intracytoplasmic sperm injection (ICSI) cycle with ≤ 3 oocytes
recruited; (ii) AFC ≤ 5-7; and (iii) anti-Mullerian hormone (AMH) ≤ 0.5 - 1.1 ng/mL were
enrolled. Exclusion criteria included donated gamete IVF cycles, thyroid disease, liver and
kidney dysfunction, and abnormal genitalia. After screening, eligible patients were randomly
allocated into two TTG intervention groups (4-week and 6-week groups) and one control group
through a manual lottery. Allocation concealment was by sequentially numbered, opaque, sealed
envelopes. All participants were blinded to group assignment, but researchers were not
blinded.
Serum testosterone are measured before treatment. Durations of androgen supplement are 4 or
6-weeks. After completing the pretreatment, patients are asked to come back when they have
menses to begin IVF treatment. Serum testosterone is measured again after the pretreatment in
both groups. Patients will be interviewed for side effects and compliance of treatment.
After treatment, patients in both group undergo IVF treatment. IVF treatment will then be
performed for all patients, according to the current hospital treatment protocols.
Patients will be followed up at least until 12th week of gestation, if they have positive
pregnancy test after embryo transfer.
Data were analyzed using STATA software version 14.0 (Stata Corporation, College Station, TX,
USA). Data were analyzed on an intention-to-treat basis. Proportions, means, and standard
deviations (SDs) were examined and presented for selected baseline variables by treatment
group. Comparisons of baseline characteristics and outcomes by treatment group were performed
with the use of ANOVA for continuous variables and a chi-square test for proportions. A
Bonferroni correction was used for multiple testing, in which the resulting P-value was
multiplied by the number of tests that measured similar constructs. Multivariable logistic
regressions were used to quantify the effects of the treatment group, adjusted for all
potential confounders including maternal age, body mass index (BMI), infertility duration,
primary or secondary infertility, and history of IVF treatment. All statistical tests were
two-sided, and P values < 0.05 were considered statistically significant.
