For IVF Protocols But rest assured, the vial contains enough leuprolide acetate to take 20 units for 14 days. Some IVF protocols start with 20 units and then decrease to 10 units once stimulation begins, while others start at 10 units and decrease to five units when stimulation begins.

Leuprolide is a gonadotrophin-releasing hormone (GnRH) agonist. It reduces the amount of hormone that stimulates ovulation. This helps to control your ovulatory cycle and prevent premature ovulation, so that your doctor can have predictable access to your eggs for IVF.

The LH surge will adequately induce maturation of the eggs for IVF. However, it is cleared from the body relatively quickly which results in elimination of the long term stimulation of the ovaries that occurs with an hCG trigger shot that lingers in the body for 10 days.

Lupron is an injectable fertility drug that is in the category of GnRH agonists used in an IVF protocol. GnRH agonists shut off your body’s normal process of hormone and egg development. As part of the Down Regulation protocol, it’s used to prevent premature ovulation during the ovarian stimulation process.

Conclusions: Leuprolide acetate similar to other GnRH agonists can improve implantation rates following IVF-ET when injected once in mid-luteal phase. The beneficial effect may be on GnRH receptors in the endometrium rather than the embryo (which had been hypothesized to direct increased placental production of hCG).

When you first begin treatment with Lupron, the estrogen levels in your body increase for 1 or 2 weeks. Some women experience a worsening of their symptoms during this time. After a few weeks, your estrogen levels will decrease, stopping ovulation and your period.

Lupron will not trigger egg maturation if used earlier since it would prevent the artificially timed production of a LH surge, which is required for the eggs to mature. Hence, Lupron can effectively trigger maturation only if the antagonist is used earlier during the IVF stimulation.

Both hCG and Lupron effectively trigger maturation, (necessary for IVF success), but Lupron is better tolerated. Although both hcg and Lupron trigger egg maturation prior to egg retrieval, Lupron can only be effective if the antagonist is used earlier during the IVF stimulation.

Lupron suppression is most commonly used during frozen embryo transfer cycles and egg donation cycles, when it is important to prevent the woman from ovulating. In the past, the drug was frequently used for ovulation suppression in fresh IVF cycles, but drugs like Cetrotide or Ganirelix are better for that purpose.

Ovulation cannot occur naturally while on Lupron because LH, which triggers ovulation, is suppressed. This prevents a premature surge of the LH before the retrieval, which could cause loss of the cycle. Once the eggs are mature, an injection of Human chorionic gonadotropin (hCG) or LH is given to stimulate ovulation.

Lupron is also used in I.V.F. cycles to improve the number and quality of eggs available for fertilization and in Egg Donation I.V.F. and Frozen Embryo Transfer to prepare the uterine lining (endometrium) for embryo transfer.

One of those is called Lupron (leuprolide acetate), a synthetic gonadotropin-releasing hormone that is often prescribed for endometriosis, as well as in vitro fertilization (IVF) cycles. It works to lower estrogen levels by regulating the body’s production of follicle stimulating hormone (FSH) and lutenizing hormone (LH).

Leuprolide acetate, sold under the brand name Lupron Depot, is taken via injections, usually starting in the cycle before IVF treatment begins. When used for IVF, Lupron may be given as one injection or daily injections.

Lupron, a GnRH agonist, is one of the best known and most hated of IVF treatment injectable fertility drugs. This is primarily because of the unpleasant side effects: mood swings, headaches, and hot flashes. GnRH agonists like Lupron are primarily used for the treatment of endometriosis and fibroids .

Estradiol in IVF supports natural estrogen needs, thickening the uterine lining so that it is prepared for implantation. It also helps the placenta to function, boosts blood flow to the uterus and prepares the body to breastfeed after birth.
