Background: Gestational trophoblastic disease (GTD) is a heterogeneous group of diseases characterized by excessive proliferating trophoblastic tissue. The prevalence of GTD has a varied geographical distribution. However, its frequency following intracytoplasmic sperm injection (ICSI) cycles has not yet been reported. This study aimed to estimate GTD frequency and prevalence after ICSI cycles.
Materials And Methods: This retrospective cross-sectional study included all patients diagnosed with GTD subsequent to ICSI and segmental embryo transfer procedure during 2011-2019 at Royan Institute. GTD diagnosis was established for patients who met all three criteria: beta-human chorionic gonadotropin (β-hCG) levels greater than 100,000 mIU/mL, vesicular ultrasonographic pattern, and presence of pathologic features of hydatidiform mole. Although we assessed the GTD frequency in all ICSI cycles, GTD cases were only observed following fresh embryo transfer ICSI procedures.
Results: We evaluated 25,667 fresh embryo transfer ICSI procedures out of 41,540 ICSI cycles. This study identified a total of 10 GTDs confirmed by all criteria which were mentioned previously. Of these 10 GTDs, nine cases had hydatidiform mole, and one had gestational trophoblastic neoplasia. The frequency of GTD was calculated 10 cases in 41,540 (0.240 per 1000) ICSI procedures and 10 in 25,667 (0.389 per 1000) fresh embryo transfers following ICSI cycles. Also, we detected 10 GTD cases in 8,196 (1.220 per 1000) clinical pregnancies.
Conclusion: We discuss that the possibility of GTD after ICSI procedure is not as low as expected. Thus, the previous theses are insufficient to explain all aspects of molar pregnancy, and more research is required.

Hox genes have been investigated in various Arthropod species, resulting in the identification of ten Hox genes, organized in a colinear arrangement within the genome. Among arthropods, crustaceans exhibit a remarkable diversity of body shapes, which are associated with a variety of egg types, embryonic development patterns, and importantly, with the modulation of Hox genes to specify the identity of body segments along the antero-posterior axis of the embryo. Although there are more than 52,000 species of crustaceans described, their genomic resources are relatively limited, making it challenging to employ several molecular tools for studying embryonic development.

Research Question: What number of retrieved oocytes is associated with the optimum chance of achieving a live birth for women undergoing ovarian stimulation with individualized follitropin delta?
Design: An individual patient data meta-analysis was performed on 1772 patients from five randomized controlled trials using individualized follitropin delta for ovarian stimulation with fixed daily dosing based on serum anti-Müllerian hormone (AMH) level and body weight. Live birth rate (LBR) and ovarian hyperstimulation syndrome (OHSS) were evaluated in relation to the number of oocytes retrieved. Predicted LBR was obtained using a logistic regression analysis with fractional polynomials.

Study Question: Is there a difference in the cumulative live birth rate (CLBR) after fresh testicular sperm aspiration (TESA) compared with the use of either pre-frozen sperm or oocyte freezing for couples experiencing ejaculation failure on the day of oocyte retrieval?
Summary Answer: After adjusting for confounding factors, the use of pre-frozen sperm or the freezing and thawing of oocytes appeared to be as effective as TESA in achieving CLBRs for couples experiencing temporary ejaculation failure.
What Is Known Already: Male patients may be concerned about experiencing temporary ejaculation failure on the day of their partner's oocyte retrieval, in which case they may choose surgical sperm retrieval, oocyte freezing on the day, or have their sperm frozen in advance. However, the clinical efficacy of these three options has not yet been evaluated.

Purpose: To compare the efficacy of modified natural cycle (mNC) preparation versus hormone replacement therapy (HRT) for endometrial preparation in recipients of donated oocytes, specifically focusing on pregnancy rates in women of advanced maternal age.
Methods: Retrospective multicenter analysis conducted between 2021 and 2024. It includes 220 cycles of fresh single blastocyst transfers resulting from oocyte donation.

Background: Techniques for sperm cryopreservation have exhibited their potential in male fertility preservation. The use of frozen-thawed sperm in fertilization (IVF) cycles is widespread today. However, many studies reported that cryopreservation might have adverse effects on sperm DNA integrity, motility, and fertilization, probably due to cold shock, intra- and extracellular ice crystals, and excess reactive oxygen species (ROS).
