✨ Progesterone ✨
Often overlooked, but absolutely essential. Progesterone is the hormone that supports implantation and early pregnancy.
👩🏽⚕️ Whether you’re trying to conceive naturally or going through IVF, it plays a vital role in preparing the body for pregnancy.
It is produced by the corpus luteum (remnant from ovulation) in the first trimester, and eventually the placenta takes over progesterone production until labour or birth!
Here’s what it does:
🌱 Thickens and stabilises the uterine lining
🛡️ Supports implantation of the embryo
🤰 Maintains pregnancy, not only prevents miscarriage in the first trimester but also has crucial roles in the 2nd and 3rd trimester.
In IVF and fertility treatment, we often prescribe extra progesterone, because sometimes, your body needs a little extra support.
Types of progesterone include:
💉 Subcutaneous (under the skin) progesterone injections have replaced Intramuscular progesterone, with significantly less side effects.
🧴 Vaginal pessaries or gels
💊 Oral tablets (less common for IVF)
The type and dose depends on your cycle, your reproductive history, underlying conditions such as endometriosis or PCOS. There’s no one-size-fits-all and that’s where personalised care comes in.
