OBJECTIVE To report a live birth after transfer of cryopreserved pronuclear embryos in cryostorage for almost 20 years. DESIGN Case report. SETTING Academic IVF center. PATIENT(S) A 42-year-old female patient with low ovarian reserve receiving donated embryos. These embryos were the result of an anonymous donation from an infertile couple who had conceived during her IVF treatment. INTE...

The objective was to understand how two forms of folate-binding protein interact to accomplish folate transport during pregnancy in swine. Specific folate binding was measured in uterine flushings during the estrous cycle and early pregnancy and in allantoic fluid (secreted form) and placental membranes (membrane form) throughout later pregnancy. In addition, the localization of the secreted fo...

PURPOSE Ovarian and uterine carcinomas manifest several differentiation patterns resembling those seen in nonneoplastic epithelia of the gynecologic tract. Specific oncogene and tumor suppressor gene defects have been associated with particular differentiation patterns in carcinomas arising in either the uterus or ovary. For instance, ovarian and uterine carcinomas with endometrioid differentia...

BACKGROUND Uterine blood flow is an important factor in uterine viability, but the number of blood vessels required to maintain viability is uncertain. In this study, indocyanine green (ICG) fluorescence imaging was used to examine uterine hemodynamics and vessels associated with uterine blood flow in cynomolgus macaque. METHODS The uterus of a female cynomolgus macaque was cut from the vagin...

BACKGROUND Uterine Tumors Resembling Ovarian Sex Cord Tumors (UTROSCT) are rare tumors of low malignancy. In the past, these tumors were mainly treated by hysterectomy. More recently, some authors have proposed conservative surgical management for women wishing to preserve fertility. This article is the first to report on organ-preserving treatment in the case of recurrence or disease persisten...

Background: Uterine factor infertility (UFI) refers to the refractory causes of female infertility stemming from the anatomical or physiological inability of a uterus to sustain gestation. Today, uterine factor infertility affects 3-5% of the population. Traditionally, although surrogacy and adoption have been the only viable options for females affected by this condition, the uterine transplan...

Information on whether a woman had ever had any children was recorded for all deaths registered to ever-married women in England and Wales between 1938 and 1960. Analysis of the relation between parity and cause of death for 1.2 million women aged 45-74 years revealed that parous women had lower mortality from breast, ovarian, and endometrial cancer than did nulliparous women but a higher morta...

BACKGROUND The effect of fibroids that do not distort the endometrial cavity on pregnancy rate (PR) and implantation rate (IR) is controversial. Use of oocyte donor-derived embryos offers an ideal patient population to study the effect of fibroids in patients utilizing assisted reproductive technologies (ARTs). METHODS We conducted a retrospective cohort study of patients undergoing oocyte do...

Background: Heterotopic pregnancy is a very rare event in natural cycle. Its incidence rising mostly due to induction of ovulation or Assisted Reproductive Technique. Most ectopic heterotopic pregnancies are localized the fallopian tubes. The occurrence molar tubal coexisting with intrauterine uncommon and consequently not often considered diagnostic possibility. Case Report: We report case 25-...

Background and Objective Administration of growth hormone (GH) during ovarian stimulation has been shown to improve success rates of in vitro fertilization. GH beneficial effect on oocyte quality is shown in several studies, but GH effect on uterine receptivity is not clear. To assess it, we studied whether GH administration can improve the chance of pregnancy and birth in women who experienced...
