Characterizing the influence of vitamin D levels on IVF outcomes.
Vitamin D deficiency is associated with lower pregnancy rates in non-Hispanic whites, but not in Asians, possibly due to their lower IVF success rates, suggesting its effect may be mediated through the endometrium. Expand
Influence of vitamin D levels on in vitro fertilization outcomes in donor-recipient cycles.
Nonreplete vitamin D status [25(OH)D<30 ng/mL] was associated with lower pregnancy rates in recipients of egg donation, and data suggest that the effects of vitamin D may be mediated through the endometrium. Expand

Estrogen and P are the only hormones necessary to prepare the endometrium for implantation and their value is unproven. Expand
Pharmacokinetics and endometrial tissue levels of progesterone after administration by intramuscular and vaginal routes: a comparative study.
Vaginal micronized P enhances P delivery to the uterus compared with a standard IM regimen and results in a synchronous secretory endometrial histology in agonadal women preparing for embryo donation. Expand
Premature luteinization as detected by elevated serum progesterone is associated with a higher pregnancy rate in donor oocyte in-vitro fertilization.
It is concluded that premature luteinization as based on elevated serum progesterone concentration is a common occurrence in oocyte donors, reflects healthy follicular development, and is associated with increased pregnancy rates. Expand
Ovarian androgen production in postmenopausal women.
The postmenopausal ovary is hormonally active, contributing significantly to the circulating pool of T, and this contribution appears to persist in women as long as 10 yr beyond the menopause. Expand
Pregnancy in the sixth decade of life: obstetric outcomes in women of advanced reproductive age.
Appropriately screened women aged 50 years or older can successfully conceive via oocyte donation and experience similar pregnancy rates, multiple gestation rates, and spontaneous abortion rates as younger recipients. Expand
Antiphospholipid antibodies and in vitro fertilization success: a meta-analysis.
The measurement of antiphospholipid antibodies is not warranted in patients undergoing IVF, and there was no significant association between antiph phosphate abnormalities and either clinical pregnancy or live birth in IVF patients. Expand
Resolution of Hormonal Markers of Ectopic Gestation: A Randomized Trial Comparing Single‐Dose Intramuscular Methotrexate With Salpingostomy
Serum progesterone levels of less than 1.5 ng/mL are a good predictor of ectopic pregnancy resolution regardless of treatment, and because its return to normal values occurs more rapidly than that of hCG levels, serum progester one may be a better marker for predicting successful treatment. Expand
Oocyte donation to women of advanced reproductive age: pregnancy results and obstetrical outcomes in patients 45 years and older.
It is concluded that oocyte donation to women of advanced reproductive age is highly successful in establishing pregnancy, however, despite careful antenatal screening, obstetrical complications are common and often secondary to multiple gestation. Expand
