Usage Examples

• Adjective:

Advanced Usage

• Progestational agent: A substance, such as a synthetic hormone, that produces effects similar to those of progesterone.

• Progestational phase: Another term for the luteal phase of the menstrual cycle, which follows ovulation and is dominated by progesterone.

Variants and Related Words

• Progesterone (n): The primary natural steroid hormone that has progestational effects, produced by the corpus luteum and placenta.

Synonyms

Notes on Different Meanings

The term "progestational" is highly specific to reproductive endocrinology and medicine. Its two core meanings are intrinsically linked: 1. The first meaning describes the biological purpose (preparing for gestation). 2. The second meaning describes the primary mechanism (via progesterone activity). In most contexts, these meanings overlap.

Adjective

1. preceding and favoring gestation; of or relating to physiological changes associated with ovulation and formation of the corpus luteum
2. of or relating to progesterone (or to a drug with effects like those of progesterone)
