Effect of Short Agonist Stop (SAS) Protocol in a Patient Having an Allergic Reaction From Conventional Ovarian Stimulating Hormone.

ABSTRACT

The case study examined a 32-year-old female and her 35-year-old partner who had experienced infertility attributed to the wife's irregular ovulation. Despite the male partner demonstrating normal reproductive parameters, he had a medical history involving hypertension. The woman also had a history of hypertension and chikungunya, which was accompanied by fever and joint pain in 2019. Due to the woman's allergic reaction to traditional ovulation stimulatory medications, the approach to assisted reproductive technologies (ART) had shifted towards employing the short agonist stop (SAS) regimen. Controlled ovarian stimulation had been achieved by administering recombinant follicular hormone, gonadotropin-releasing hormone (GnRH), and estrogen. The SAS protocol had been introduced to counter premature ovulation and synchronize follicular development. Following two successful ovum pickup procedures resulting in the retrieval of six embryos, the initial frozen embryo transfer took place in April 2022. Daily progesterone supplementation had been administered to sustain the patient's luteal phase. A subsequent human chorionic gonadotropin (ß-hCG) test performed on the 14th day post-embryo transfer confirmed a positive pregnancy diagnosis, with a measured outcome of 2026 mIU/mL. This case highlighted the potential impact of medication allergies on fertility outcomes and underscored the unique approach of the SAS protocol in managing allergic responses during in vitro fertilization (IVF) procedures. Despite the patient's history of allergic reactions to conventional ovulation stimulatory medications, the study concluded that the implementation of the brief agonist stop strategy had resulted in a successful clinical pregnancy.
