Dydrogesterone as an oral alternative to vaginal progesterone for IVF luteal phase support: A systematic review and individual participant data meta-analysis.

The aim of this systematic review and meta-analysis was to conduct a comprehensive assessment of the evidence on the efficacy and safety of oral dydrogesterone versus micronized vaginal progesterone (MVP) for luteal phase support. Embase and MEDLINE were searched for studies that evaluated the effect of luteal phase support with daily administration of oral dydrogesterone (20 to 40 mg) versus MVP capsules (600 to 800 mg) or gel (90 mg) on pregnancy or live birth rates in women undergoing fresh-cycle IVF (protocol registered at PROSPERO [CRD42018105949]). Individual participant data (IPD) were extracted for the primary analysis where available and aggregate data were extracted for the secondary analysis.

A Phase III randomized controlled trial of oral dydrogesterone versus intravaginal progesterone gel for luteal phase support in fertilization (Lotus II): results from the Chinese mainland subpopulation.

Lotus II, a randomized, open-label, multicenter, international study compared the efficacy and safety of oral dydrogesterone versus micronized vaginal progesterone (MVP) gel for luteal support in IVF. A prespecified subgroup analysis was performed on 239 Chinese mainland subjects from the overall study population ( = 1034), who were randomized to oral dydrogesterone 30 mg or 8% MVP gel 90 mg daily from the day of oocyte retrieval until 12 weeks of gestation. The aim was to demonstrate non-inferiority of oral dydrogesterone to MVP gel, assessed by the presence of a fetal heartbeat at 12 weeks of gestation.

Dydrogesterone: pharmacological profile and mechanism of action as luteal phase support in assisted reproduction.

The pharmacological and physiological profiles of progestogens used for luteal phase support during assisted reproductive technology are likely to be important in guiding clinical choice towards the most appropriate treatment option. Various micronized progesterone formulations with differing pharmacological profiles have been investigated for several purposes. Dydrogesterone, a stereoisomer of progesterone, is available in an oral form with high oral bioavailability; it has been used to treat a variety of conditions related to progesterone deficiency since the 1960s and has recently been approved for luteal phase support as part of an assisted reproductive technology treatment.

Oral dydrogesterone versus intravaginal micronized progesterone gel for luteal phase support in IVF: a randomized clinical trial.

Study Question: Is oral dydrogesterone 30 mg daily non-inferior to 8% micronized vaginal progesterone (MVP) gel 90 mg daily for luteal phase support in IVF?

Summary Answer: Oral dydrogesterone demonstrated non-inferiority to MVP gel for the presence of fetal heartbeats at 12 weeks of gestation (non-inferiority margin 10%).

What Is Known Already: The standard of care for luteal phase support in IVF is the use of MVP; however, it is associated with vaginal irritation, discharge and poor patient compliance. Oral dydrogesterone may replace MVP as the standard of care if it is found to be efficacious with an acceptable safety profile.

Dydrogesterone use in early pregnancy.

Successful oocyte implantation and a favorable pregnancy outcome rely on optimal progesterone levels. Therefore, progesterone deficiencies associated with infertility and miscarriage have commonly been treated with progestogens that mimic the activity of progesterone. Among those is dydrogesterone, an oral retrosteroid with a structure closely related to that of progesterone yet with a greater bioavailability and higher selectivity for the progesterone receptor.

Dydrogesterone treatment for menstrual-cycle regularization in routine clinical practice: a multicenter observational study.

Dydrogesterone is an oral retroprogesterone widely used to treat progesterone deficiencies, including irregular menstrual cycles (MCs). This prospective, non-interventional, single-arm, post-marketing, observational study evaluated the effects of dydrogesterone on MC regularization. Women aged 18-40 years who had been prescribed dydrogesterone to treat irregular MCs due to progesterone deficiency were enrolled across 64 centers in Russia, Ukraine, Kazakhstan and Uzbekistan.

A 6-month observational study of energy, sexual desire, and body proportions in hypogonadal men treated with a testosterone 1% gel.

Aims And Methods: This was a 6-month, open label, multinational, observational study in hypogonadal men treated with daily titrated dose of 50, 75, or 100 mg 1% testosterone gel (AndroGel®) in community practice. Primary outcome was effect of treatment on hypogonadal symptoms and quality of life as assessed by Aging Males' Symptoms (AMS) scale. Secondary objectives included erectile dysfunction (International Index of Erectile Function [IIEF]), fatigue (Multidimensional Fatigue Inventory [MFI]), and surrogates for body composition (waist circumference, body mass index [BMI]).

Oral estradiol and dydrogesterone combination therapy in postmenopausal women: review of efficacy and safety.

HRT is known to be effective for the relief of menopausal symptoms and prevention of osteoporosis. HRT should be tailored to the woman, enhancing the beneficial effects of the treatment while minimizing the risks. It is difficult to evaluate data on particular preparations of HRT and the different dosages in isolation.

Rationale, design and methods of the ESPRIT study: Energy, Sexual desire and body PropoRtions wIth AndroGel, Testosterone 1% gel therapy, in hypogonadal men.

Hypogonadism is associated with a range of disease states that have significant effects on morbidity and mortality, and also affect quality of life. The ESPRIT study (Energy, Sexual desire and body PropoRtions wIth AndroGel, Testosterone 1% gel therapy) is a 6-month, multinational, open label, observational study in hypogonadal men being treated with transdermal AndroGel in usual daily clinical practice; 1,700-2,400 patients will be enrolled in Canada, Germany, Central and Eastern Europe, Russia and the Middle East. The main objective will be to evaluate the effect of AndroGel on symptoms of hypogonadism and quality of life as assessed by the Aging Males' Symptoms scale.
