Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study compared the therapeutic effect of 4- and 6-week TTG application before controlled ovarian hyperstimulation (COH) in POR.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Testosterone gel 4 weeks

Patients with low ovarian reserve received 4-week TTG application before controlled ovarian hyperstimulation.

Group Type EXPERIMENTAL

Testosterone gel

Intervention Type DRUG

Apply 12.5mg testosterone gel to the abdomen and rub on with one finger, once a day, in the morning, then allow sites to dry and cover with clothing. Continue the treatment for 4 or 6 weeks until next IVF treatment.

Testosterone gel 6 weeks

Patients with low ovarian reserve received 6-week TTG application before controlled ovarian hyperstimulation.

Group Type EXPERIMENTAL

Testosterone gel

Intervention Type DRUG

Apply 12.5mg testosterone gel to the abdomen and rub on with one finger, once a day, in the morning, then allow sites to dry and cover with clothing. Continue the treatment for 4 or 6 weeks until next IVF treatment.

Control group

Patients with low ovarian reserve received no medication before controlled ovarian hyperstimulation.

Group Type NO_INTERVENTION
