OBJECTIVE: The optimal gestational duration for twin gestations is unknown. Epidemiologic studies show that the lowest perinatal mortality rate for twins is at 37-38 weeks, but these studies lack information on pregnancy complications and neonatal morbidities. This study evaluates pregnancy characteristics and perinatal outcomes of twins in order to assess ...

Endocrine data and characteristics of nonconceptive ovarian cycling and pregnancy are limited within the genus Callithrix to the common marmoset (C. jacchus) and Wied's black tufted-ear marmoset (C. kuhlii). This article presents patterns of urinary pregnanediol-3-glucuronide (PdG) excretion, as determined by enzyme immunoassay, throughout the course of ovarian cycling and ...

Heterotopic pregnancy describes the relatively rare coexistence of one or more intrauterine gestations and one or more extrauterine (ectopic) gestations. We describe a unique clinical case involving successful treatment of an ovarian heterotopic pregnancy through gestational sac aspiration and injection of hyperosmolar glucose. A 31-year-old woman presented with an ovarian ...

It is generally accepted that progesterone (P4) is a key regulator of reproductive function in mammals. In cattle, the primary focus of P4's actions has been uterine receptivity and maintenance of pregnancy. Studies in mammalian laboratory species and ovarian derived cell lines also highlight their role in ovarian function. Extensive ...

The modern domestic sow exhibits a period of impaired reproductive performance known as seasonal infertility during the late summer and early autumn months. A reduction in farrowing rate due to pregnancy loss is the most economically significant manifestation of this phenomenon. Presently, little is known of the aetiology of seasonal ...

Mammals such as cattle, swine, sheep and humans are born with a highly variable number of ovarian follicles and oocytes in the ovaries that dwindle during ageing and are never replenished. This variation in the ovarian reserve is reflected in the numbers of antral follicles in the ovaries at all ...

Monozygotic multiple pregnancies are three times more common after assisted reproduction (with or without IVF) than after spontaneous conception (1.2% versus 0.4%). These pregnancies are associated with multiple maternal and fetal risks. This article is a description of nine cases of monozygotic pregnancies following IVF at the OVO Clinic (Montreal) ...

A 30-years-old Taiwanese female in her second pregnancy spontaneously conceived a monochorionic twin pregnancy. A routine ultrasound at 27 weeks of gestation revealed a selective intrauterine growth restriction (sIUGR) fetus and an appropriate gestational age (AGA) fetus. The AGA fetus was found to have a fetal intra-abdominal umbilical vein (FIUV) ...

Despite the fact that ovarian stimulation is controlled, it is not always predictable. Because the day of human chorionic gonadotrophin (hCG) injection depends mainly on the patient's ovarian response to gonadotrophins, the day of oocyte retrieval cannot be determined in advance. As a result, oocyte retrievals are often scheduled to ...

Trisomy is the most common type of chromosome abnormality, affecting 4% of clinically recognised pregnancies, of which, trisomies 16, 21 and 22 are the most prevalent. It has been suggested that a large proportion of maternally derived trisomic pregnancies, specifically trisomy 21, are the result of low-level ovarian mosaicism. In ...

The total number of ovarian follicles ≥3mm in diameter (antral follicle count, AFC) during follicular waves varies among cattle of similar age, but AFC is highly repeatable within individuals. We hypothesized that lower AFC could be associated with reduced fertility in cattle. The AFC was assessed by ultrasonography for 2 ...

Luteinizing hormone (LH) is believed to play a role in follicle maturation during the natural cycle. However, the need for co-treatment with recombinant LH (rLH) for controlled ovarian stimulation is controversial. The primary objective of our study was to determine if pregnancy rates are improved when rLH is used in ...

Ovarian stimulation and intrauterine insemination (OS/IUI), a mainstay of current infertility therapy and a common antecedent to IVF, is a significant driver of the multiple births epidemic. Redress of this challenge, now marking its quarter centennial, will require a rethinking of current practice patterns. Herein we explore prospects for prevention, ...

Superovulation procedures and assisted reproductive technologies (ART) have provided the means for significant improvement in infertility care. Although generally safe, these procedures are associated with complications that, albeit rare, can have significant morbidity. Complications from superovulation include ovarian hyperstimulation syndrome, thromboembolism, and adnexal torsion. Complications from oocyte retrieval include infection, ...

Infertility is a major problem in Nigeria, which has caused many couples to be burdened with physical, psychological and social issues. IVF (In-vitro fertilization) has played a major role in reducing the burden among infertile couples. However, despite the role of IVF in solving infertility in Nigeria, it is important ...

With the availability of and improvements in in vitro fertilization (IVF), the role of reproductive surgery has been questioned. Yet, the scope of reproductive surgery today is much larger than in the past. Hysteroscopic correction of intrauterine disease is an important endoscopic procedure in women with infertility. Evidence suggests that correction ...

Much effort has been focused on improving assisted reproductive technology procedures in humans and nonhuman primates (NHPs). However, the pregnancy rate after embryo transfer (ET) has not been satisfactory, indicating that some barriers still need to be overcome in this important procedure. One of the key factors is embryo–uterine synchronicity, ...
