Fertility preservation in men with hypogonadotropic hypogonadism secondary to germinoma: two cases of gonadotropin replacement therapy before induction of anticancer chemotherapy.
Article in International cancer conference journal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Hypogonadotropic hypogonadism can be caused by brain tumors. For a malignancy such as a germ cell tumor, chemotherapy combined with radiation is administered. In patients who wish for children, the inability to undergo sperm cryopreservation before treatment because of impaired spermatogenesis and/or ejaculation dysfunction can be problematic. We herein present two cases involving a 26-year-old man and a 30-year-old man with hypogonadotropic hypogonadism due to an intracranial germinoma and both wished to have children. Gonadotropin replacement therapy prior to anticancer chemotherapy resulted in subsequent spontaneous pregnancy or assisted reproductive therapy. Subsequent treatment of the tumor resulted in no recurrence for 9 and 2 years, respectively. Close consultation with an oncologist is mandatory in such cases. Depending on the tumor prognosis, however, it may be possible to delay tumor treatment and prioritize fertility because there is a possibility of impaired spermatogenesis due to additional chemotherapy.
