Objective: The objective of the study was to determine the efficacy of a novel "stair-step" clomiphene protocol in women with polycystic ovarian syndrome (PCOS) who do not respond to 50 mg clomiphene.
Study Design: This was a retrospective analysis at an academic fertility center. The stair-step protocol is performed as follows: 50 mg clomiphene for 5 days, ultrasonography on days 11-14. If unresponsive, immediately begin 100 mg clomiphene for 5 days and repeat ultrasound in 1 week. If still unresponsive, begin 150 mg clomiphene for 5 days and repeat the ultrasound in 1 week. Stair-step cycles were compared with published historical clomiphene outcomes for women who were nonresponsive.
Results: The time to ovulation was 32-53 days less with the stair-step protocol compared with a traditional regimen. The dose-dependent ovulation rate was 64% at 100 mg with the stair-step protocol compared with 22% with a traditional regimen.
Conclusion: It is not necessary to induce menses before increasing clomiphene doses in nonresponsive PCOS patients.

Splenic injury is a potentially fatal injury if left undetected or untreated. Although most splenic injuries result from a traumatic event, it is important to consider if one's history (past or present) increases their risk for splenic injury (i.e.

Polycystic ovary syndrome (PCOS) is characterized by menstrual irregularities, high androgen levels, and ovarian cysts. Clomiphene citrate (Clomid) and letrozole have both been investigated as ovulation induction therapies for PCOS. This interventional study aimed to compare the efficacy and safety of a stairstep practice of letrozole versus clomiphene citrate in women with PCOS.

On day 0 of years 1 and 2, 64 Brangus crossbred heifers per year were stratified by initial body weight (BW) and age (mean = 257 ± 20 kg and 271 ± 22 d) and allocated into 16 bahiagrass (Paspalum notatum) pastures (4 heifers per pasture per yr). Treatments were randomly allotted to pastures in a 2 × 2 factorial arrangement of treatments (4 pastures per treatment per yr). Treatments consisted of concentrate dry matter (DM) supplementation at 1.

Background: Various strategies have been proposed for polycystic ovary syndrome (PCOS) treatment.
Objective: To investigate and compare the number and size of ovarian follicles, endometrial thickness, and ovulation rate by traditional protocol (TP) and stair-step protocol (SSP).
Materials And Methods: Sixty infertile PCOS women were allocated into two groups (SSP = 30 and control TP = 30) between May and October 2019 in the Besat Hospital, Sanandaj, Iran.

Purpose: We sought to compare the efficacy of the letrozole (LTZ) stair-step protocol with clomiphene citrate (CC) stair-step protocol in the management of 150 mg dose of CC-resistant polycystic ovary syndrome (PCOS) patients.
Methods: We retrospectively compared a total of 61 patients diagnosed as being resistant to the traditional CC protocol who were subsequently managed using the LTZ stair-step protocol with CC-resistant 56 patients who were treated with CC stair-step protocol. The number of follicles ≥18 mm, endometrial thickness, time to ovulation, clinical pregnancy rates, multiple pregnancy rates, spontaneous abortion rates, live birth rates, and systemic side effects in patients were evaluated.
