Abstract
PURPOSE OF REVIEW The use of progestins as pituitary suppressors has increased progressively, along with more detailed indications for their use, thereby consolidating an alternative approach to the personalization of ovarian stimulation. RECENT FINDINGS Based on the ability of progesterone to inhibit ovulation, progestins have been used in ovarian stimulation (OS) follicular protocols to prevent a luteinizing hormone surge in patients undergoing in vitro fertilization (IVF), as an alternative to gonadotropin-releasing hormone (GnRH) analogue administration. This review explores the different types of progestogen protocols and their efficacy depending on the type of population or reproductive procedure in which they are administered and in comparison with that of GnRH analogues. Their effect on oocytes and embryos and their safety and cost-effectiveness are also analyzed. SUMMARY Progestins have proven their effectiveness as a gonadotropin adjuvant in terms of ovarian response, reproductive outcome, and safety. In addition, they offer the convenience of oral administration and a lower cost than GnRH analogues. Whereas oocytes or embryos should be vitrified as it displaces the receptive period with the consequent asynchrony between embryo and endometrium. The evidence endorses progestins as a more friendly approach to OS, especially when frozen-thawed embryo transfer is planned.

Progestin primed ovarian stimulation using dydrogesterone from day 7 of the cycle onwards in oocyte donation cycles: a longitudinal study. Reprod Biomed Online 2024; 48:103732. [PMID: 38458058 DOI: 10.1016/j.rbmo.2023.103732] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 10/15/2023] [Accepted: 11/17/2023] [Indexed: 03/10/2024]
Abstract
RESEARCH QUESTION Does a progestin-primed ovarian stimulation (PPOS) protocol with dydrogesterone from cycle day 7 yield similar outcomes compared with a gonadotrophin-releasing hormone (GnRH) antagonist protocol in the same oocyte donors? DESIGN This retrospective longitudinal study included 128 cycles from 64 oocyte donors. All oocyte donors had the same type of gonadotrophin and daily dose in both stimulation cycles. The primary outcome was the number of cumulus-oocyte complexes (COC) retrieved. RESULTS The number of COC retrieved (mean ± SD 19.7 ± 10.8 versus 19.2 ± 8.3; P = 0.5) and the number of metaphase II oocytes (15.5 ± 8.4 versus 16.2 ± 7.0; P = 0.19) were similar for the PPOS and GnRH antagonist protocols, respectively. The duration of stimulation (10.5 ± 1.5 days versus 10.8 ± 1.5 days; P = 0.14) and consumption of gonadotrophins (2271.9 ± 429.7 IU versus 2321.5 ± 403.4 IU; P = 0.2) were also comparable, without any cases of premature ovulation. Nevertheless, there was a significant difference in the total cost of medication per cycle: €898.3 ± 169.9 for the PPOS protocol versus €1196.4 ± 207.5 (P < 0.001) for the GnRH antagonist protocol. CONCLUSION The number of oocytes retrieved and number of metaphase II oocytes were comparable in both stimulation protocols, with the advantage of significant cost reduction in favour of the PPOS protocol compared with the GnRH antagonist protocol. No cases of premature ovulation were observed, even when progestin was started later in the stimulation.

Ata B, Kalafat E. Progestin-primed ovarian stimulation: for whom, when and how? Reprod Biomed Online 2024; 48:103639. [PMID: 38159467 DOI: 10.1016/j.rbmo.2023.103639] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Revised: 10/10/2023] [Accepted: 10/18/2023] [Indexed: 01/03/2024]
Abstract
Progestin-primed ovarian stimulation (PPOS) is being increasingly used for ovarian stimulation in assisted reproductive technology. Different progestins have been used with similar success. The available studies suggest a similar response to ovarian stimulation with gonadotrophin-releasing hormone (GnRH) analogues. Any differences in the duration of stimulation or gonadotrophin consumption are minor and clinically insignificant. PPOS has the advantage of oral administration and lower medication costs than GnRH analogues. As such it is clearly more cost-effective for fertility preservation and planned freeze-all cycles, but when fresh embryo transfer is intended PPOS can be less cost-effective depending on the local direct and indirect costs of the additional initial frozen embryo transfer cycle. Oocytes collected in PPOS cycles have similar developmental potential, including blastocyst euploidy rates. Frozen embryo transfer outcomes of PPOS and GnRH analogue cycles seem to be similar in terms of both ongoing pregnancy/live birth rates and obstetric and perinatal outcomes. While some studies have reported lower cumulative live birth rates with PPOS, they have methodological issues, including arbitrary definitions of the cumulative live birth rate. PPOS has been used in all patient types (except progesterone receptor-positive breast cancer patients) with consistent results and seems a patient friendly and cost-effective choice if a fresh embryo transfer is not intended.

Reprod Biomed Online 2024; 48:103626. [PMID: 38160486 DOI: 10.1016/j.rbmo.2023.103626] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Revised: 10/12/2023] [Accepted: 10/16/2023] [Indexed: 01/03/2024]
Abstract
RESEARCH QUESTION Does the trigger to oocyte retrieval interval (TORI) affect oocyte maturation rates differently in progestin-primed ovarian stimulation (PPOS) and gonadotrophin-releasing hormone (GnRH) antagonist cycles? DESIGN This was a retrospective cohort study. The interaction between the stimulation protocol and TORI was assessed in a linear mixed effects multivariable regression analysis with oocyte maturation rate as the dependent variable, and stimulation protocol (GnRH antagonist or PPOS), age (continuous), gonadotrophin type (FSH or human menopausal gonadotrophin), trigger (human chorionic gonadotrophin [HCG] or GnRH agonist), TORI (continuous) and days of stimulation (continuous) as the independent variables. Oocyte maturation rate was defined as number of metaphase II oocytes/number of cumulus-oocyte complexes retrieved. The maturation rate was calculated per cycle and treated as a continuous variable. RESULTS A total of 473 GnRH antagonist and 205 PPOS cycles (121 conventional PPOS and 84 flexible PPOS) were analysed. The median (quartiles) female age was 36 (32-40) years. Of these cycles, 493 were triggered with HCG and 185 with a GnRH agonist. The TORI ranged between 33.6 and 39.1 h, with a median (quartiles) of 36.2 (36-36.4) hours. Maturation rates were similar between fixed PPOS, flexible PPOS and antagonist cycles (median 80%, 75% and 75%, respectively, P = 0.15). There was no significant interaction between the stimulation protocols and TORI for oocyte maturation. CONCLUSIONS PPOS cycles do not seem to require a longer TORI than GnRH antagonist cycles.

Abstract
Objective To explore the cycle characteristics and pregnancy outcomes of progestin-primed ovarian stimulation (PPOS) using fixed versus degressive doses of medroxyprogesterone acetate (MPA) in conjunction with letrozole (LE) in infertile women by propensity score matching (PSM) analysis. Design A retrospective cohort study. Setting Tertiary-care academic medical center. Population A total of 3173 infertile women undergoing their first in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) treatment within the period from January 2017 to December 2020. Methods A total of 1068 and 783 patients who underwent a fixed dose of MPA combined with LE and a degressive dose of MPA combined with LE protocols, respectively, were enrolled in this study. The freeze-all approach and later frozen-thawed embryo transfer (FET) were performed in both groups. Propensity score matching (1:1) was performed. Main outcome measures The primary outcomes were the dosage of MPA and the incidence of premature luteinizing hormone (LH) surges. The secondary outcomes were the number of oocytes retrieved, the cumulative live birth rate (CLBR) and the fetal malformation rate. Results We created a perfect match of 478 patients in each group. The dosage of MPA, the LH serum level on the eighth day of stimulation, progesterone (P) level and LH level on the hCG trigger day were significantly higher in the LE + fixed MPA group than in the LE + degressive MPA group (52.1 ± 13.1 mg vs. 44.9 ± 12.5 mg; 5.0 ± 2.7 IU/L vs. 3.7 ± 1.7 IU/L; 0.9 ± 0.5 ng/ml vs. 0.8 ± 0.5 ng/ml; 3.3 ± 2.4 IU/L vs. 2.8 ± 1.9 IU/L; P < 0.01). The duration of Gn, the number of follicles with diameter more than 16 mm on trigger day, the estradiol (E2) level on the hCG trigger day were lower in the LE + fixed MPA group than in the LE + degressive MPA group (9.7 ± 1.7 days vs. 10.3 ± 1.5 days; 5.6 ± 3.0 vs. 6.3 ± 3.0; 1752.5 ± 1120.8 pg/ml vs. 1997.2 ± 1108.5 pg/ml; P < 0.001). No significant difference was found in the incidence of premature LH surge, the number of oocytes retrieved, the number of top-quality embryos, clinical pregnancy rate (CPR), CLBR or fetal malformation rate between the two groups. Conclusion The combination of a degressive MPA dose with LE proved effective in reducing the total MPA dosage with comparable premature LH surge and pregnancy outcomes in women undergoing the PPOS protocol.

Abstract
INTRODUCTION Despite the many unknowns about its exact mechanism, progesterone and progestins are being successfully used to prevent luteinizing hormone (LH) surge during ovarian stimulation for assisted reproductive technology (ART). We will review progestin primed ovarian stimulation (PPOS) protocols in comparison with gonadotropin releasing hormone (GnRH) analogues and each other. EVIDENCE ACQUISITION MEDLINE via PubMed; Cochrane Central Register of Controlled Trials (CENTRAL); Scopus; Web of Science were screened with keywords related to assisted reproductive technology, ovarian stimulation progesterone, GnRH analogue and progesterone in several combinations. Search period was from the date of inception of each database until 20 May 2022. EVIDENCE SYNTHESIS Live birth or ongoing pregnancy rate per embryo transfer (ET) was similar in PPOS and GnRH antagonist cycles (RR=1.16, 95% CI: 0.93-1.44). Clinical pregnancy rate per ET was likewise similar (RR=1.12, 95% CI: 0.92-1.37). Miscarriage rate per pregnancy was similar with PPOS and GnRH antagonists in autologous cycles (RR=1.01, 95% CI: 0.65-1.55). Pooled analyses showed similar live birth rate between progestins and short GnRH agonist protocols (RR=1.01, 95% CI: 0.49-2.09), however, clinical pregnancy rates per ET were significantly higher with progestins (RR=1.31, 95% CI: 1.06-1.62). Miscarriage rate per pregnancy was similar with progestins (RR=0.82, 95% CI: 0.55-1.21). CONCLUSIONS Progestins seem to be an efficient option for pituitary suppression during ovarian suppression, providing similar outcomes for stimulation and pregnancy. They can be especially beneficial for women for whom fresh ET is not considered.

Abstract
RESEARCH QUESTION To compare the cumulative live birth rate (CLBR) per oocyte retrieval cycle of a conventional progestin-primed ovarian stimulation (cPPOS) regimen with a flexible progestin-primed ovarian stimulation (fPPOS) regimen in poor ovarian response patients, according to POSEIDON criteria. DESIGN Poor ovarian response women, according to POSEIDON criteria, who underwent the first PPOS protocol for in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) between January 2018 and December 2020 were included. The fPPOS group involved 113 participants, and the cPPOS group included 1119 participants. In the cPPOS group, medroxyprogesterone acetate (MPA) (10 mg/d) was administrated on the gonadotropin injection the same day as gonadotropin injections in the cPPOS group, while MPA was started either on the day when the leading follicle with mean diameter > 12mm was present and/or serum E2 was >300 pg/mL in the fPPOS protocol group. The primary outcome was CLBR. RESULTS The fPPOS protocol had higher CLBR per oocyte retrieval cycle compared to the cPPOS group, even without a statistically significant difference (29.6% vs. 24.9%, p = 0.365). The fPPOS group had fewer numbers of retrieved oocytes (2.87 ± 2.03 vs. 3.76 ± 2.32, p < 0.001) but a higher MII oocyte rate (89.8% vs. 84.7%, p = 0.016). In addition, the number of available embryos in the two groups was comparable (1.37 ± 1.24 vs. 1.63 ± 1.38, p = 0.095). There were five women in the fPPOS group, and 86 women in the cPPOS group had a premature LH surge (4.2% vs. 6.8%, p = 0.261). In the fPPOS group, there was one instance of premature ovulation, while in the cPPOS group, there were six occurrences of premature ovulation (0.8 vs. 0.5%, p = 1.000). CONCLUSION(S) The novel fPPOS protocol appears to achieve higher CLBR even without significant differences and with MPA consumption compared with cPPOS protocol in low-prognosis patients.

Abstract
PURPOSE Flexible progestin-primed ovarian stimulation (PPOS) protocol is demonstrated to be effective in suppressing premature luteinization in few studies. We aimed to compare fixed and flexible PPOS protocols in preventing premature luteinization in patients with diminished ovarian reserve. METHODS This retrospective cohort study included patients with a diminished ovarian reserve who were administered PPOS protocols for pituitary suppression during ovarian stimulation in a tertiary center in between January 2019 and June 2022. At fixed protocol, 20 mg/day dydrogesterone was started in cycle day two or three along with gonadotropins and continued until trigger day. In contrast, at flexible protocol, 20 mg/day dydrogesterone was commenced when the leading follicle reached 12 mm or serum estradiol (E2) level was > 200 pg/mL. RESULTS A total of 125 patients, of whom 83 were administered fixed PPOS protocol and 42 were administered flexible PPOS protocol, were included in the analysis. Both groups had similar baseline characteristics and cycle parameters, including total days of gonadotropin administration and total gonadotropin dose (p > 0.05). Premature luteinization occurred at 7.2% and 11.9% of patients in fixed and flexible PPOS protocols, respectively (p = 0.505). Retrieved oocytes numbers, metaphase II oocyte numbers, and 2PN numbers were also similar (p > 0.05). Clinical pregnancy rates per transfer were 52.5% in fixed and 36.4% in flexible protocols (p = 0.499). CONCLUSION Both fixed and flexible PPOS protocols had statistically similar outcomes in preventing premature luteinization and other cycle parameters. The flexible PPOS protocol seems to be as effective as the fixed PPOS protocol for patients with diminished ovarian reserve; however, further prospective studies should be conducted to validate the results of our research.
