Semen Analysis and in vitro Fertilization [PDF]

Archives of Andrology, 1985
Thirty-seven patients underwent ultrasonographic, clinical, and hormonal monitoring of superovulated cycles in order to time HCG administration in an attempt to schedule the laparoscopy at the optimal time for oocyte recovery. Superovulation was induced by Clomiphene in patients under the age of 35, with both ovaries; Clomiphene and HMG were ...

Algorithms for Predicting the Probability of Azoospermia from Follicle Stimulating Hormone: Design and Multi-Institutional External Validation

The World Journal of Men's Health, 2022
Purpose: To predict the probability of azoospermia without a semen analysis in men presenting with infertility by developing an azoospermia prediction model. Materials and Methods: Two predictive algorithms were generated, one with follicle stimulating

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

Molecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Translating whole‐genome doubling into precision medicine in cancer

Molecular Oncology, EarlyView.
Whole‐genome doubling creates a WGD‐positive tumor state characterized by persistent chromosomal instability, karyotypic diversification, and cellular stress. These same biological pressures drive aggressive tumor evolution while exposing therapeutic vulnerabilities, providing a rationale for WGD‐informed precision medicine. Whole‐genome doubling (WGD)

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer

Molecular Oncology, EarlyView.
Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

Does sperm DNA fragmentation correlate with semen parameters?

Reproductive Medicine and Biology, 2019
Purpose This study aimed to investigate the association between sperm quality assessed by routine semen analysis and sperm DNA integrity assay. Methods In our cross‐sectional study, a total of 318 men from the infertile couples were enrolled from ...

Comparison of pre-operative and post-operative (varicocelectomy) sperm parameters in patients suffering varicocle with and without reflux in Doppler ultrasonography

Journal of Family Medicine and Primary Care, 2019
Background: Varicocele can cause progressive testicular damage and infertility. Severe retrograde blood flow to the internal spermatic vein has been suggested as a risk factor for infertility or progressive/stable varicocele. We have aimed to Compared th

Spatial biology in cancer epigenetics

Molecular Oncology, EarlyView.
Spatial epigenomics combines molecular profiling with tissue architecture to reveal how gene regulation is organized within intact tissues. In cancer, these technologies uncover the mechanisms driving tumor heterogeneity and microenvironmental interactions, opening new opportunities for biomarker discovery and precision medicine.
