However, a 2014 review concluded the following on the topic of progesterone for enhancing breast development in transgender women:
Our knowledge concerning the natural history and effects of different cross-sex hormone therapies on breast development in [transgender] women is extremely sparse and based on low quality of evidence. Current evidence does not provide evidence that progestogens enhance breast development in [transgender] women. Neither do they prove the absence of such an effect. This prevents us from drawing any firm conclusion at this moment and demonstrates the need for further research to clarify these important clinical questions. Data on menstruating women shows there is no correlation between water retention, and levels of progesterone or estrogen. Despite this, some theorise progesterone might cause temporary breast enlargement due to local fluid retention, and may thus give a misleading appearance of breast growth. Aside from a hypothetical involvement in breast development, progestogens are not otherwise known to be involved in physical feminization.In some cases, transgender women use progesterone to alleviate symptoms of estrogen withdrawal. Estrogen must be withdrawn from transgender womens hormonal regime before they undergo sex reassignment surgery. Pregnancy support
Vaginally dosed progesterone is being investigated as potentially beneficial in preventing preterm birth in women at risk for preterm birth. The initial study by Fonseca suggested that vaginal progesterone could prevent preterm birth in women with a history of preterm birth. According to a recent study, women with a short cervix that received hormonal treatment with a progesterone gel had their risk of prematurely giving birth reduced.
Fluconazole, amphotericin B, and other antifungals may also be used. Treatment normally continues for two weeks after resolution of signs and symptoms and Candida yeasts can no longer can be cultured from blood samples. Some forms of invasive candidiasis, such as infections in the bones, joints, heart, or central nervous system, usually need to be treated for a longer period. Retrospective observational studies suggest that prompt presumptive antifungal therapy (based on symptoms or biomarkers) is effective and can reduce mortality. Epidemiology
Invasive candidiasis is estimated to affect more than 250,000 people and cause more than 50,000 deaths worldwide every year. The CDC estimates that approximately 46,000 cases of healthcare-associated invasive candidiasis occur each year in the US. The estimated mortality attributable to fungemia is 19-40%. However, because the majority of people who develop invasive candidiasis are already sick, it can be difficult to determine if the cause of death is directly attributable to the fungal infection. Fungemia is one of the most common bloodstream infections in the United States. In general, observed incidence rates have been stable or trending higher but declining rates have been achieved with improvements in hygiene and disease management.Deep-seated infections in bones, muscles, joints, eyes, or central nervous system can arise from a bloodstream infection or direct inoculation of Candida may occur, for example, during intestinal surgery.The distribution of Candida species causing invasive candidiasis has changed over the past decades. C. albicans had been the dominant pathogen but now accounts for just half of the isolates.
