“…In 1997, Hwang et al (32) reported the birth of a healthy baby by caesarean delivery after oocyte retrieval, in vitro maturation, and intracytoplasmic sperm injection (ICSI) in a donation program. High conception rates after forced intercourse and heteropaternal superfecundation or superfetation could be explained by a stress-induced LH surge that may occur at any point of the menstrual cycle and even during periods of amenorrhea related to pregnancy and lactation (33)(34)(35).…”

“…A thorough review conducted by Pape et al in 2008 identified fewer than 10 reported cases. 1 Subsequent reports have been published, including a case in 2010 by Lantieri et al, 4 another in 2019 by Ito et al, 5 and three in 2021: one by Alten et al, 6 one by Windaro et al, 7 and the latest by Segal et al 2 Of these reports, three cases, ours being the fourth, report superfetation resulting in HP. 4,5,7 Superfetation is an uncommon occurrence due to the usual suppression of follicular development, halting of ovulation, and subsequently amenorrhea during pregnancy.…”

“…When superfetation occurs intrauterine atop an existing intrauterine pregnancy, it can result in diamniotic dizygotic twins with notably different gestational ages. 1,2,6,[9][10][11][12][13] The diagnosis of superfetation, in this case, can be suspected by observing discordance in growth during pregnancy by serial ultrasound scans and excluding usual causes of intrauterine growth retardation, such as chronic vascular or renal diseases, severe anemia, etc. Postdelivery, examining the placenta and cords for abnormalities assessing newborns in the neonatal intensive care unit (NICU), or utilizing X-rays to determine bone age, can further support the diagnosis.…”

Key Clinical MessageTo raise awareness about the increasing incidence of superfetation and heterotopic pregnancy in patients with ovarian induction, their insidious symptoms of abdominal pain, anemia, and hemodynamic instability in early pregnancy, and the usefulness of transvaginal ultrasound (TVUS) and quantitative beta human chorionic gonadotrophin (b‐hCG) for diagnosis.AbstractSuperfetation, occurrence of ovulation, fertilization, and implantation during an ongoing pregnancy and heterotopic pregnancy (HP) simultaneous presence of intrauterine and extrauterine pregnancies are infrequent phenomena. We report a case where both coexisted, challenges in diagnosis and management and association with the widespread use of assisted reproductive technologies (ARTs). A 32‐year‐old woman, who previously underwent ovulation induction therapy, presented with abdominal pain at 8 weeks pregnancy according to her last menstrual period. The patient had high quantitative serum beta‐human chorionic gonadotropin (b‐hCG) (30,883 mIU/mL). She was vitally stable and not anemic. Transvaginal ultrasound (TVUS) revealed two pregnancies at different gestational ages: an intrauterine pregnancy at 5 weeks and 3 days, and a right intact tubal ectopic pregnancy at 10 weeks and 5 days. Superfetation resulting in HP was then diagnosed. Subsequently, the patient underwent right laparoscopic salpingectomy. The intrauterine pregnancy progressed normally, resulting in delivery of a healthy full‐term neonate via Cesarean section at 38 weeks. Superfetation is typically rare from suppression of follicular development and ovulation during pregnancy. Various theories have been proposed to explain its etiology, including polyovulation, delayed blastocyst implantation, and abnormal estrogen and b‐hCG surges. In superfetation, an embryo resulting from a previous conception coexists with another embryo, either intrauterine, resulting in diamniotic dizygotic twins with significantly different gestational ages, or extrauterine resulting in HP. Despite being particularly challenging to diagnose because its presenting symptoms can overlap with those of other more common clinical conditions in early pregnancy, HP is increasingly seen with ARTs. In addition, the treatment of HP is versatile, ranging from expectant management to laparoscopic surgery. High level of suspicion for HP and superfetation is crucial in patients who, after ART, present with abdominal pain, hemodynamic instability, or anemia. Additionally, patients planning to undergo subsequent ART cycles should be thoroughly screened with b‐hCG and TVUS to exclude an ongoing intrauterine or extrauterine pregnancy.

“…This reproductive strategy has been documented in many taxa, including angiosperm plants (Kennedy 1978), viviparous fishes (Scrimshaw 1944;Reznick et al 2007) and in at least ten different orders of mammals (Roellig et al 2011), including humans (Pape et al 2008;Lantieri et al 2010). In altricial birds, clutch overlap represents a similar phenomenon because the parents provide care to distinct sets of offspring in different stages of development (Burley 1980).…”

Superfoetation is the ability of females to simultaneously bear multiple broods of embryos at different developmental stages. Most studies on the phylogenetic distribution of superfoetation and on the factors that potentially promote superfoetation ignore variation within species. Here, we studied 11 populations of two species of viviparous fishes of the family Poeciliidae (Poeciliopsis gracilis and Poeciliopsis infans) and document wide variation in superfoetation and in three related life history traits: brood size, individual embryo mass and total reproductive allotment. We found significant differences in the average number of simultaneous broods among populations of P. gracilis but not among populations of P. infans. In addition, we found even greater variation between months within populations for both species, although no specific pattern of temporal variation was evident. Instead of the expected consistency of seasonal differences in superfoetation across populations, we found that large variation among months within seasons and the amount and direction of this monthly variation differed widely between populations. Our results emphasize the importance of including intraspecific variation in superfoetation and other life history traits in studies that aimed at finding general explanations of life history trait evolution.
