In 1960, it was estimated that 20 million Accepted 10-11-2020 pregnancies were exposed to Dydrogesterone in utero. LOTUS I and LOTUS II two major multicenter Available online 13-03-2021 Phase III studies were conducted on patients who were planning to undergo In Vitro Fertilization (IVF) with or without Intracytoplasmic Sperm Injection (ICSI). The result of both studies shows that Dydrogesterone was non-inferior to micronized vaginal progesterone, which was the presence of fetal heartbeats at 12 weeks Keywords: of gestation. Progesterone which can be administered either by oral preparation, vaginal administration LPD along with optimal use of estrogen and Gonadotropin-Releasing Hormon (GnRH) agonist drugs is used in LOTUS the treatment of LPD. Studies have suggested the use of Dydrogesterone in fresh IVF cycles and Luteal Progesterone Phase Support (LPS) is continued till 10–12 weeks. -
The Progestogen Only Pill
The Progestogen Only Pill Mini-pill or POP A service provided by page 2 of 8 How does the progestogen only pill (POP) work? The progestogen only pill mainly works by thickening the mucus you produce from your cervix. This makes it more difficult for sperm to get to the egg. It can also sometimes stop your ovaries from producing an egg (ovulation). How effective is the pill? The effectiveness of the pill depends on the woman taking it. At best it is over 98% effective (when no pills are missed). However failure rates can be much higher (9-15%) if women do not remember to take their pill properly. Missed pills can lead to pregnancy. Advantages of the POP • It doesn’t interfere with sex. • You can use it whilst you are breastfeeding. • It is useful if you cannot take oestrogen (the hormone contained in the combined oral contraceptive) • Can be used at any age even if you smoke and are over 35 years of age. • It may help with premenstrual symptoms and painful periods. page 3 of 8 Disadvantages of the POP • You have to remember to take your pill at the same time every day. • Your periods may become irregular or even stop altogether on the POP, this is not dangerous but if you miss a period you need to check that you are not pregnant by coming to clinic for a pregnancy test. • You may get some temporary side effects, such as spotty skin, breast tenderness and mood changes, though these should stop within a few months. -
Differential Effects of Hormones on Cellular Metabolism in Keratoconus
www.nature.com/scientificreports OPEN Differential Effects of Hormones on Cellular Metabolism in Keratoconus In Vitro Received: 27 October 2016 Tina B McKay1, Jesper Hjortdal2, Henrik Sejersen2 & Dimitrios Karamichos1,3 Accepted: 18 January 2017 Keratoconus (KC) is a corneal thinning disease with an onset commonly immediately post-puberty Published: 17 February 2017 and stabilization by 40 to 50 years of age. The role of hormones in regulating corneal tissue structure in homeostatic and pathological conditions is unknown. Our group recently linked altered hormone levels to KC. Our current study sought to investigate and delineate the effects of exogenous hormones, such as androgen, luteotropin, and estrogen, on corneal stroma bioenergetics. We utilized our established 3D in vitro model to characterize the effects of DHEA, prolactin, 17β-estradiol on insulin- growth factor-1 and -2 (IGF-1, -2) signaling and metabolic function in primary corneal fibroblasts from healthy controls (HCFs) and KC patients (HKCs). Our data showed that exogenous DHEA significantly downregulated IGF-1 and its receptor in both HCFs and HKCs with HKCs showing consistently lower basal pentose phosphate flux. Prolactin caused no significant change in IGF-1 levels and an increase in IGF-2 in HKCs correlating with an increase in ATP and NADH levels. 17β-estradiol led to a significant upregulation in pentose phosphate flux and glycolytic intermediates in HCFs. Our results identified hormone-specific responses regulated in HKCs compared to HCFs revealing a novel role for hormones on bioenergetics in KC. Sex hormones play a functional role in regulating growth and reproduction, systemic metabolism, and cellular differentiation and functionality1–3. -
