Detailed Description
Studies in primates showed that treatment with testosterone increased the number of growing follicles, lead to proliferation of granulosa and theca cells, while finally reduced the apoptosis of granulosa cells (Vendola et al., 1999; Weil et al., 1999). These studies further suggest that androgens may have a specific action in pre-antral and small antral follicles, prior to serving as substrate for estradiol synthesis in larger follicles and in this regard influence the responsiveness of the ovaries to gonadotropins and amplify the effects of FSH on the ovary.
Despite the available evidence, only 3 small RCTs evaluated the effect of transdermal testosterone on infertile patients with poor ovarian response to stimulation. A pooled analysis of these studies demonstrated a benefit in clinical and ongoing pregnancy rates for testosterone pre-treated patients (González-Comadran et al., 2012). However, two of these trials were considerably small, whereas all of them restricted testosterone administration between 5 and 21 days prior ovarian stimulation. Evidence from basic research and early trials suggest that androgens should be administered for at least 2 months before initiation of ovarian stimulation (Casson PR, 2000), in order affect preantral follicles and equip them with more FSH receptors in an attempt to have a larger cohort of follicles surviving to the recruitable antral stage.
Taking into account the promising results from recently conducted small RCTS, the investigators decided to perform a double blind placebo controlled randomized controlled trial, with adequate sample size, in order to test the effect of administration of transdermal testosterone in poor ovarian responders fulfilling the Bologna criteria, for 2 months prior ovarian stimulation in a long agonist protocol. The daily dose of transdermal testosterone gel (TTG) will be 0.55gr (5.5mg testosterone/day). The specific dose was selected based on previous pharmacokinetic studies in women according to which daily application of 5 mg of transdermal testosterone cream (Fooladi, 2014) or TTG (Singh et al. 2006, Nathorst-Böös et al., 2005) is likely to restore fT levels to the premenopausal reference range. Although no side effects had been described after pre-treatment with higher doses of 12.5mg TTG for 21 days in a previous randomized controlled trial (Kim et al., 2011), it is likely that higher doses will result in supraphysiological TT and fT levels. Therefore the dose of 0.55gr TTG (5.5mg testosterone/day) has been selected for the T-TRANSPORT trial since this will restore TT and fT levels to levels above and within the upper normal reference range.

Intervention / Treatment |
---|---|
Experimental: Transdermal testosterone gel
Patients will receive once daily application of 0.55 gr TTG (Testosterone gel 1%; Laboratories Besins International,Paris,France) with a 5.5 mg/d nominal delivery rate of testosterone starting from day 1 or 2 of the following menstrual cycle, for approximately 65 days. Pituitary down-regulation will be induced by daily injections of 0.1mg triptorelin started on day 21 of the next cycle following enrollment in the study, up to and including the day of hCG administration. After 2 weeks of down-regulation, daily SC injections of HP-hMG (Menopur®) (300 IU/day) will be administered up to the day of hCG administration. Ovulation triggering will be induced with 250μg rhCG (Ovidrelle®) followed by oocyte pick-up ~36 hours later and ICSI. A maximum of 2 embryos, following each center's national criteria of single embryo transfer, will be transferred 3 days later. Luteal phase support with be performed with progesterone tablets ( Utrogestan®) (200mg x3, intravaginally). |
Patients will receive once daily application of 0.55 gr testosterone gel-TTG (GROUP A) (Testosterone gel 1%; Laboratories Besins International, Paris, France) with a 5.5 mg/d nominal delivery rate of testosterone starting from day 1 or 2 of the following menstrual cycle, for approximately 65 days. The application will be administered in the morning by the patient onto clean dry healthy skin over external surface of the thighs. The gel will be simply spread on the skin gently as a thin layer. TTG will start on the day of enrollment and will continue until patients' menstruation (28-30 days). Daily administration of TTG or placebo will continue for 35 days (21days until the initial of downregulation with triptorelin and for 14 more days until the initiation of ovarian stimulation with HP-hMG). Ovarian stimulation will commence the day after last testosterone gel application. (GROUP A)
