NCT07224438

Kisspeptin Administration Subcutaneously to Patients With Hypothalamic Amenorrhea

The goal of this study is to see whether kisspeptin, a naturally occurring hormone, can stimulate the release of other reproductive hormones in women with hypothalamic amenorrhea (HA). The investigators are also examining whether kisspeptin can help women release eggs from their ovaries. Kisspeptin will be administered subcutaneously (SC) for two weeks in a pulsatile fashion. Ultrasound monitoring of ovarian follicular growth and frequent blood sampling (every 10 minutes for up to two hours) will be performed to assess the physiologic response to kisspeptin over time.

Kisspeptin Administration Subcutaneously to Patients With IHH

The goal of this study is to see whether kisspeptin, a naturally occurring hormone, can stimulate the release of other reproductive hormones in men and women with idiopathic hypogonadotropic hypogonadism (IHH). The investigators are also examining whether kisspeptin can help women release eggs from their ovaries. Kisspeptin will be administered SC for two weeks in a pulsatile fashion. Ultrasound monitoring of ovarian follicular growth (for women) and frequent blood sampling (every 10 minutes for up to 70 minutes) will be performed to assess the physiologic response to kisspeptin over time.

Assessment of Endometrial Thickness Among Adolescent and Young Adult Patients on Estrogen Replacement Therapy Using Daily Oral Micronized Progesterone Versus the Etonogestrel Implant.

The goal of this observational study is to compare endometrial stripe thickness in adolescent and young adult (AYA) patients with a uterus on estrogen replacement therapy using oral progesterone versus the etonogstrel implant for endometrial protection. The main questions it aims to answer are: Aim 1: Characterize the mean endometrial thickness in AYA on estrogen hormone replacement therapy before initiation of progesterone therapy Aim 2: Characterize the mean changes and variability in endometrial thickness in AYA treated for 6 months with either the etonogestrel implant or continuous oral progesterone Aim 3: Assess satisfaction, side effects, bleeding patterns, any progesterone modifications, and adherence in AYA treated for 6 months with either etonogestrel implant or continuous progesterone Participants will be asked to: * Get two pelvic ultrasounds * Fill out two surveys * Continue their current hormone replacement therapy * Initiate one of two progesterone therapies (prometrium 100mg daily or Nexplanon) Researchers will compare the change in endometrial thickness after 6 months of progesterone use to see if there is a significant difference in the mean change between the prometrium and Nexplanon groups.

Growing up With the Young Endocrine Support System (YESS!)

Transition from paediatric to adult endocrinology is a challenge for adolescents, families and doctors. Up to 25% of young adults with chronic endocrine disorders are lost to follow-up ('drop-out') once the young adult moves out of paediatric care. Non-attendance and sub-optimal medical self-management can lead to serious and expensive medical complications. In a pilot study, adolescents suggested the use of e-technology to become more involved in the transition process. The investigators have designed and developed the YESS! game, a tool to help improve medical self-management in adolescents with chronic endocrine disorders. The hypothesis is that adolescents playing the YESS! game will show a larger increase in self-management score during the first year of transition and will have a lower drop-out rate at the adult endocrine outpatient clinic (OPC), compared to adolescents who do not play the game.
