The most rigorous study to date, published in Nature Communications (2026) and led by Dexeus Mujer, shows that transdermal testosterone <strong>does not improve pregnancy rates<\/strong> in women with low ovarian reserve. The results were 15.7% versus 14.9%, with no significant difference.<\/p>\n<h3 class=\"subtitulo-h3\" style=\"color: #333;\">What is low ovarian reserve?<\/h3>\n<p><strong>Low ovarian reserve<\/strong> indicates that the number of eggs available in the ovaries is lower than expected for the woman\u2019s age. It can affect the response to ovarian stimulation and the chances of pregnancy through IVF. It is diagnosed using AMH testing and antral follicle count.<\/p>\n<h3 class=\"subtitulo-h3\" style=\"color: #333;\">Can I get pregnant with low ovarian reserve?<\/h3>\n<p><strong>Yes<\/strong>. Having low ovarian reserve does not prevent pregnancy, but it requires a <strong>personalised strategy<\/strong>. At Dexeus Mujer, we assess each case individually to determine the best treatment: IVF using your own eggs, oocyte banking or egg donation.<\/p>\n<h3 class=\"subtitulo-h3\" style=\"color: #333;\">Should I use testosterone before my IVF?<\/h3>\n<p>According to current scientific evidence, <strong>there is no justification<\/strong> for the routine use of transdermal testosterone before IVF in women with diminished ovarian reserve. Its use merely delays the start of treatment by 9 weeks without providing any benefits.<\/p>\n<h3 class=\"subtitulo-h3\" style=\"color: #333;\">What does it mean for a study to be triple-blind?<\/h3>\n<p>A <strong>triple-blind<\/strong> design means that neither the patients, nor the doctors treating them, nor the researchers analysing the results know who is receiving the active treatment and who is receiving the placebo. This design is the most rigorous in clinical research because it <strong>eliminates conscious and unconscious<\/strong> biases that could affect the results. It is the gold standard for establishing causal relationships with a high degree of certainty.<\/p>\n<h3 class=\"subtitulo-h3\" style=\"color: #333;\">Are there effective alternatives for women with low ovarian reserve?<\/h3>\n<p>Yes.
