#203 : Amazing Low-Cost IVF/ICSI Induction Protocols in Developing Countries

Fertility & Reproduction, 2023
Background and Aims: Basically, main cost of IVF is expensive use of gonadotrophins along with agonist or antagonist which are aimed mainly to avoid premature LH surge. Since LH surge is preceded by estrogen surge and inflammatory reaction, so all theory

GnRH antagonist-induced inhibition of the premature LH surge increases pregnancy rates in IUI-stimulated cycles. A prospective randomized trial [PDF]

Human Reproduction, 2006
Our prospective randomized controlled trial was designed to assess whether the use of GnRH antagonists can improve the success rate of controlled ovarian stimulation (COS)/intrauterine insemination (IUI) treatments, via inhibition of the premature LH rise.A total of 104 patients were randomly divided, using a randomization list, into two groups: in ...

The Comparison of Fixed and Flexible Progestin Primed Ovarian Stimulation on Mature Oocyte Yield in Women at Risk of Premature Ovarian Insufficiency

Frontiers in Endocrinology, 2022
While gonadotrophin releasing hormone (GnRH) antagonists have been the standard of pituitary suppression during ovarian stimulation for ART, progestin primed ovarian stimulation (PPOS) has emerged as an alternative.

Comparative efficacy and safety of cetrorelix with or without mid-cycle recombinant LH and leuprolide acetate for inhibition of premature LH surges in assisted reproduction

Reproductive BioMedicine Online, 2004
An open label, randomized, multi-centre study was performed to compare cetrorelix and leuprolide acetate for prevention of premature LH surge and to assess whether patients treated with cetrorelix benefit from addition of recombinant human (r-h)LH. Normo-ovulatory women (n = 74) undergoing ovarian stimulation prior to intracytoplasmic sperm injection ...

Clomiphene citrate in LH surge suppression for women undergoing ICSI

Middle East Fertility Society Journal, 2018
Objective: To evaluate the effect of adding clomiphene citrate (CC) in the mid-to-late follicular phase as an adjuvant to gonadotropins to suppress luteinizing hormone (LH) surge in women undergoing intracytoplasmic sperm injection (ICSI).

HDAC3 maintains oocyte meiosis arrest by repressing amphiregulin expression before the LH surge. [PDF]

, 2019
It is known that granulosa cells (GCs) mediate gonadotropin-induced oocyte meiosis resumption by releasing EGF-like factors in mammals, however, the detailed molecular mechanisms remain unclear.

Exogenous progesterone for LH surge prevention is redundant in ovarian stimulation protocols

, 2021
During ovarian stimulation for IVF–embryo transfer treatment, a premature LH surge may lead to progesterone elevation that disrupts endometrial maturation and affects the probability of pregnancy following fresh embryo transfer.
