However, not all patients diagnosed with PHP properly respond to ovulation induction. Thus, a poor response may indicate decreased ovarian reserve or reflect a deficiency in other key components of ovarian function. Here we presented a rare case of a 24-year-old woman diagnosed with PHP and poor response to previous gonadotropin therapy. In our protocol the patient received first growth hormone (GH) replacement for 5 months before starting gonadotropins. When the serum IGF-I (insulin grow factor-I) level normalized, she started ovulation induction with 225 IU/day of human menopausal gonadotropin (hMG). After the ninth day of the cycle, ultrasounds were performed every 2 days to control follicular growth. The puncture of the follicles was performed on the twentieth day of the cycle and a surprising number of 13 oocytes were collected. The oocytes were fertilized by the classical IVF method, resulting in 11 D3 embryos, of which 2 were freshly transferred. Beta hCG hormone levels were determined, and a single fetus pregnancy was confirmed. The birth was by cesarean section at 38 weeks of gestation.

This evaluation includes blastomere number, size, fragmentation, multinucleation, blastocyst (BL) expansion, and the inner-cell mass and trophectoderm appearance. However, this method requires removing embryos from the incubator, exposing them to non-physiological conditions such as fluctuations in pH, temperature, gases concentrations, as well as significant inter-observer variability. Continuous embryo culture using time-lapse monitoring (TLM) has revolutionized embryo evaluation by allowing continuous, real-time tracking of embryo development from fertilisation to blastocyst formation. This reduces the need to remove embryos from the incubator and helps maintain stable culture conditions. The monitoring system typically includes a standard incubator with an integrated microscope coupled to a digital camera, capturing images at regular intervals that are processed into a video for analysis. Despite its advantages, accurately predicting implantation rates in humans remains challenging. Recently, artificial intelligence (AI) has emerged as promising tool to objectively evaluate human embryos. AI can analyse large datasets, including embryological, clinical, and genetic information, and assist in individualizing treatment protocols. Integrating AI with TLM could improve embryo selection and enhance overall success rates.
