A group of infertility patients were evaluated by an endometrial biopsy, timed with a basal body temperature chart, serum luteinizing hormone radioimmunassay to pinpoint ovulation, and daily serum progesterone values during a control and a treatment cycle. Progesterone in the suppository or intramuscular form and 17-hydroxyprogesterone caproate* were administered during the luteal phase to a group of volunteer patients with normal corpus luteum function to determine if these compounds would depress serum progesterone levels as do certain progestational agents. There was no apparent inhibition of corpus luteum function as no decrease in progesterone production occurred. Despite the additive effect of progesterone administration demonstrated by elevated serum levels, endometrial biopsies remained in phase when dated from the estimated day of ovulation.

Luteal phase defect (LPD) accounts for a significant proportion of reproductive disorders, however its etiology is still debated. A prospective study was performed on 37 ovulatory women to determine whether LPD can occur in cycles characterized by completely normal folliculogenesis. Criteria for normal a gradual rise of serum estradiol, a luteinizing hormone (LH) surge, the presence of a dominant follicle that disappeared, an increase of serum progesterone, and normal serum levels of prolactin, testosterone, dehydroepiandrosterone sulfate, follicle-stimulating hormone, and LH. Thirty of 37 women fulfilled the above mentioned strict criteria and underwent endometrial biopsy in the late luteal phase. Seven of 30 (23%) demonstrated a delay in endometrial development and all had normal hormonal and ultrasonographic parameters of folliculogenesis and ovulation. Women with delayed endometrial development demonstrated slightly longer follicular phases (17.0 +/- 1.1 versus 14.5 +/- 0.3 days). Perfectly normal follicular and periovulatory events may be followed by deficient luteal phases.

The authors have further analyzed women diagnosed as having luteal phase insufficiency in hope of determining the value of specific screening tests as well as determining the degree of heterogeneity of pathophysiologic mechanisms involved in the disorder. Twelve women with the disorder were identified, 6 with two consecutive midluteal serum progesterone (P) levels less than 10 ng/ml (group 1) and 6 with two consecutive late luteal phase endometrial biopsies out of phase (group 2); 4 infertile women with normal serum P and late luteal biopsies also were studied (group 3). All underwent serum sampling for P and luteinizing hormone (LH) at 20-minute intervals for 24 hours, beginning at 9:00 A.M. of day 7 post-LH surge. No significant differences were noted among the three groups for LH area under the curve, pulse frequency, or pulse amplitude. Furthermore, no differences were ascertained for P area under the curve. However, individuals were identified who had one or more hormonal abnormalities but no abnormal biopsy, as well as patients with normal hormonal profiles but having abnormal endometrial development. Receiver Operating Characteristic curves demonstrated that pooled morning serum P levels provided optimal predictive ability of biopsy results. The authors conclude that luteal phase insufficiency is a heterogeneous disorder, and that neither endometrial biopsy nor serum hormonal analysis obviates the need for the other.

Plasma progesterone concentrations drawn at the time of endometrial biopsy in 26 infertility patients with histologically documented luteal phase inadequacy were compared with those of 26 infertility patients with normal biopsies. Although as a group the former patients had lower progesterone values and shorter cycles, there was considerable overlap. Therefore, although plasma progesterone determinations and temperature charts are useful in the detection of ovulation and in the interpretation of the biopsy results, a properly obtained endometrial biopsy is essential for the diagnosis of luteal phase inadequacy.
EndometriosisAMH and Ovarian ReserveSurgical Staging and TypologyAnti-Müllerian Hormone
Endometriosis is a chronic, gynecologic condition in which tissue similar to the lining of the uterus implants throughout the body. Women with endometriosis have a higher prevalence of infertility and a greater risk of early natural menopause compared to those without endometriosis. This study aimed to evaluate preoperative serum AMH levels among women with and without incident endometriosis and to assess whether levels differ by surgical staging and typology. The ENDO (Endometriosis: Natural History, Diagnosis, and Outcomes) study was conducted between 2007 and 2009. The ENDO study consisted of an operative and population cohort (n=600). Only those in the ENDO operative cohort from the Utah site were used for this analysis, and included women aged 18 to 44 years who were scheduled for gynecologic surgery, irrespective of clinical indication (n=476). AMH levels were measured from stored serum collected before surgery using a quantitative enzyme-linked immunosorbent assay. After excluding participants with missing outcome data (n=51), unilateral oophorectomy (n=8), or those within the population cohort (n=69), 348 participants remained for the analysis. Surgically confirmed endometriosis diagnosis, staging (American Society for Reproductive Medicine I-IV), and typology (superficial, deep, ovarian) were ascertained by the operative report. Outliers for AMH (>14.0 ng/mL) were excluded from the analyses and AMH values were log-transformed. Multivariable linear regression models adjusted for age (squared and continuous), body mass index, serum cotinine levels, and exogenous hormonal contraceptive use were conducted. Percentage differences in AMH were calculated as (exp[β]-1)×100, and 95% confidence intervals were reported. Compared with no endometriosis, incident endometriosis diagnosis was associated with lower AMH levels (-19.8%; 95% confidence interval, -37.0 to 1.0); however, this association was not statistically significant. Stage III to IV disease was associated with 40.1% lower AMH levels (95% confidence interval, -58.9 to -12.7). Ovarian endometriomas were most strongly associated with lower AMH levels (-54.3%; 95% confidence interval, -69.4 to -31.8), with a more pronounced association among those with infertility (-72.6%; 95% confidence interval, -85.4 to -48.5). Deep (-24.1%; 95% confidence interval, -48.2 to 11.0) and superficial (-15.5%; 95% confidence interval, -34.6 to 9.3) endometriosis also showed a trend toward lower AMH levels, but these findings were not statistically significant. Compared with a postoperative diagnosis of a normal pelvis, incident endometriosis was associated with 26.8% lower AMH levels (95% confidence interval, -44.6 to -3.4). Stage III to IV disease was associated with 47.8% lower AMH levels (95% confidence interval, -65.8 to -23.2), and all subtypes of endometriosis were statistically significantly associated with lower levels of AMH compared with a postoperative diagnosis of a normal pelvis (ovarian: -60.8%; 95% confidence interval, -74.4 to -39.9; -34.3%; 95% confidence interval, -56.2 to -1.4; -24.8%; 95% confidence interval, -43.9 to -0.8). Ovarian and moderate to severe (stage III-IV) endometriosis were associated with markedly lower AMH levels compared with no endometriosis. Compared with a postoperative diagnosis of a normal pelvis, incident endometriosis and moderate to severe stages (stage III-IV) were associated with statistically significantly lower AMH levels. Additionally, typology (deep, ovarian, or superficial) was associated with statistically significantly lower AMH levels. However, this association was likely driven by the presence of ovarian endometriomas across all subtypes. These findings are consistent with previous studies and demonstrate that endometriosis lesions themselves, independent of surgical intervention, influence AMH levels.
