Progesterone plays a key role in implantation. Several studies reported that lower luteal progesterone levels might be related to decreased chances of pregnancy. This systematic review was conducted using appropriate key words, on MEDLINE, EMBASE, and the Cochrane Library, from 1990 up to March 2021 to assess if luteal serum progesterone levels are associated with ongoing pregnancy (OP) and live birth (LB) rates (primary outcomes) and miscarriage rate (secondary outcome), according to the number of corpora lutea (CLs). Overall 2,632 non-duplicate records were identified, of which 32 relevant studies were available for quantitative analysis. In artificial cycles with no CL, OP and LB rates were significantly decreased when the luteal progesterone level falls below a certain threshold (risk ratio [RR] 0.72; 95% confidence interval [CI] 0.62-0.84 and 0.73; 95% CI 0.59-0.90, respectively), while the miscarriage rate was increased (RR 1.48; 95% CI 1.17-1.86). In stimulated cycles with several CLs, the mean luteal progesterone level in the no OP and no LB groups was significantly lower than in the OP and LB groups [difference in means 68.8 (95% CI 45.6-92.0) and 272.4 (95% CI 10.8-533.9), ng/ml, respectively]. Monitoring luteal serum progesterone levels could help in individualizing progesterone administration to enhance OP and LB rates, especially in cycles without corpus luteum.

Although adequate luteal hormone production is essential for establishing pregnancy, luteal phase deficiency (LPD) is poorly characterized among eumenorrheic women. We assessed the prevalence and overlap of two established LPD diagnostic criteria: short luteal phase duration less than10 days (clinical LPD) and suboptimal luteal progesterone of 5 ng/mL or less (biochemical LPD) and their relationship with reproductive hormone concentrations.
Design, Setting, and We conducted a prospective study in western New York (2005-2007) following 259 women, aged 18-44 years, for up to two menstrual cycles. Among ovulatory cycles with recorded cycle lengths (n = 463), there were 41 cycles (8.9%) with clinical LPD, 39 cycles (8.4%) with biochemical LPD, and 20 cycles (4.3%) meeting both criteria. Recurrent clinical and biochemical LPD was observed in eight (3.4%) and five (2.1%) women, respectively. Clinical and biochemical LPD were each associated with lower follicular estradiol (both P ≤ .001) and luteal estradiol (P = .03 and P = .02, respectively) after adjusting for age, race, and percentage body fat. Clinical, but not biochemical, LPD was associated with lower LH and FSH across all phases of the cycle (P ≤ .001). Clinical and biochemical LPD were evident among regularly menstruating women. Estradiol was lower in LPD cycles under either criterion, but LH and FSH were lower only in association with shortened luteal phase (ie, clinical LPD), indicating that clinical and biochemical LPD may reflect different underlying mechanisms. Identifying ovulation in combination with a well-timed luteal progesterone measurement may serve as a cost-effective and specific tool for LPD assessment by clinicians and researchers.
To evaluate the luteal phase in women with rigorously defined unexplained infertility. Prospective study. National Center for Infertility Research at Michigan. PATIENT(S): Evaluation of 1,885 women with infertility identified 12 women who met the rigorously defined criteria for unexplained infertility: [1] infertility of > or = 24 months duration, with no male factor, anatomic-functional disorders of the reproductive tract, or immunologic infertility; [2] normal body mass index (BMI); [3] ovulatory cycles ranging from 26 to 32 days; [4] normal luteal phase determined by endometrial biopsy; and [5] normal baseline hormonal profile. Controls (n = 12) were healthy, parous women with normal ovulatory cycles, normal hormonal screen, and were matched for age and BMI to patients. MAIN OUTCOME MEASURE(S): Pattern of follicular growth rate and luteal phase hormonal profile. RESULT(S): Women with unexplained infertility did not differ in menstrual cycle characteristics, follicular growth rate or mean preovulatory follicle diameter, or endometrial biopsy dating. The mean levels of P tended to be lower in the unexplained infertility group throughout the luteal phase, but only the midluteal interval reached statistical significance. Luteal phase mean integrated P or urinary PDG levels of unexplained infertility women did not differ from those of fertile controls. The ratio of integrated E2:P also was significantly greater in women with unexplained infertility than in fertile controls. CONCLUSION(S): Women with rigorously defined unexplained infertility have subtle hormonal anomalies during the luteal phase when compared with fertile controls.
To correlate luteal estradiol (E2) levels with pregnancy outcome, 36 consecutive conceptions resulting from gamete intrafallopian transfer in gonadotropin releasing hormone agonist/human menopausal gonadotropin (GnRH-a/hMG) cycles were analyzed. GnRH-a was initiated during the preceding luteal phase. HMG was adjusted individually. Human chorionic gonadotropin (hCG), 5,000 IU, was administered when E2 was > 500 pg/mL and the leading follicle > 17 mm (day 0). The luteal phase was supported by (1) hCG, 1,500 IU in three doses from day 5 and (2) progesterone (P) from day 7. E2 and P levels were analyzed in three groups of normally progressing pregnancy (NPP), abortion (AB) and preclinical abortion (PAB). No significant differences in mean E2 levels were seen between the groups from day 0 through day 5 after hCG. Midluteal E2 levels were significantly different between the groups (P < .05). Late luteal E2 values were significantly higher for NPP than for either AB or PAB (P < .05). There were no significant differences in luteal P values between the NPP, AB and PAB groups. Decreased luteal E2 appears to be associated with early pregnancy wastage; this may be due to inadequate endometrial support.
To assess the sensitivity and specificity of common clinical tests used for the diagnosis of luteal phase defect (LPD). The sensitivity and specificity of these tests for predicting low integrated P levels over the luteal phase were calculated. Outpatient reproductive endocrinology and infertility clinic at a university medical center. Fifty-eight strictly defined normal women were used to determine normal integrated luteal phase P levels. The study population was a separate 34 women who either were normal (n = 15) or were being evaluated for infertility or recurrent abortion (n = 19). These 34 study subjects all had the following tests performed in the same menstrual cycle: daily reproductive hormone levels, daily assessment of preovulatory follicle size, late luteal endometrial biopsies, and BBT charts. Basal body temperature, maximum preovulatory follicle size, dated endometrial biopsies, and serum P levels (single and multiple) were used in an attempt to predict which patients had low integrated P levels. Unacceptably low sensitivity and/or specificity levels were found for the following tests: appearance of BBT charts, luteal phase length, and preovulatory follicle diameter. Timed endometrial biopsy was found to have marginally acceptable sensitivity and specificity levels whether dated by next menstrual period or midcycle events. The best test for the prediction of low integrated P was a single serum P level from the midluteal phase that was < 10 ng/mL (31.8 nmol/L) or a sum of three random serum P measurements that was < 30 ng/mL (95.4 nmol/L) (also obtained in the midluteal phase). Luteal phase defect is a relatively uncommon but important cause of infertility and/or habitual abortion. The recommended test for the determination of LPD is a midluteal phase single serum P level < 10 ng/mL or the sum of three serum P levels that is < 30 ng/mL. The endometrial biopsy is a second line test that is only recommended when LPD needs to be evaluated in a treated cycle (ovulation induction or supplemental P).
